I'm interested in seeing how many amps and batteries everyone is running with. Not only that, but the approx. # of total RMS watts your pushing. <BR> <BR>I'm pushing approx 1000watts using 2 amps and 2 batteries. I'm adding a 3rd amp that will add an additional 1000watts. wondering if i should get a 3rd marine battery or not. (i'm sure ppl will start sayin i should get a kinetik power cell or something like that instead of another battery).

trickyboarder08 03-31-2008 12:06 PM

I am running 1100 watts RMS using 2 batteries. One cranking battery and one dedicated to the music. <BR> <BR>Do you have a cranking batter plus 2 batteries, or one cranking and one for the amps. If you only have one for the amps. IMO I would get another if you decide to add that 1000watt RMS amp.

05mobiuslsv 03-31-2008 12:08 PM

Steve I'm running 2500 watts rms and have 5 optima batteries, one is a reserve starting. Only put this many in because we like to chill alot, or tie up at the beach. If you don't listen to the stereo alot with the boat off you'd be ok with 3. I recomend having a reserve starting battery just in case anytime you run a larger stereo system.

sidekicknicholas 03-31-2008 12:09 PM

I've got <BR>AMPS = 1000watts -- 660watts <BR>1 Battery

denverd1 03-31-2008 12:10 PM

1800 watts. 3 amps. 4 batts. 2 - 12vt and 2 6vt for acccessories. <BR> <BR>If you don't plan to chill and listen, you could prolly just add the amp.

bkoz 03-31-2008 12:26 PM

Why not just run 2 really good batteries and wire the power for your amps through the "both" or "all" post on your switch? That way you can run the stereo off either battery and just switch back and forth? I ran 3 amps with 2 batteries in my last boat like that and it worked great, plan on doing the same in this one. Also I run the remote wire from each of my amps through its own switch so I can turn my amps on/off when I need to.

dabell 03-31-2008 12:35 PM

3 Arc Audio amps <BR>1 - KS1000.1 <BR>2 - KS300.4 <BR> <BR>4 interstate batteries <BR>1 - starting <BR>3 - stereo <BR> <BR>That is what Lightning Accessories suggested and seems to be a good setup so far.

acurtis_ttu 03-31-2008 12:40 PM

I have 4 amps ( 3 alpine pdx, 1 mmats) 2700 RMS. I have one starting, 2 6v t-105's ( golf cart). 90 amp alt. I can definately tell the effeciency of the alpine amps over my previous setup justy by watching the voltmeter while the boat is running.

suprasteve 03-31-2008 12:55 PM

<b>Adam</b> thats another concern i'm starting to think of is the alternator. What is the factory alternator rated for? <BR> <BR><b>Byron</b> thats kind of what i do now, but i'm having a feeling that the new zx1000.1 might suck alot more juice. I want to make sure i'm giving the amp ample battery juice so that thing can make my sub put ripples in the glass(water)!!!!

05mobiuslsv 03-31-2008 12:58 PM

Steve if you have the indmar 340 you will have the 90 amp alternator, if you have the 325 it will be the 70 amp alternator. The 90 amp alternator puts out 40 amps at idle.

chpthril 03-31-2008 1:41 PM

2 Amps and 2 dedicated deep cycles. Watts RMS = 970.

fitzh2o 03-31-2008 1:43 PM

This is a really good subject-got a 2000 watt amp for christmas from my bro, been working on getting parts together to do it right and theft proof(proof probably is not the correct word- maybe deterent is better)with tamper-proof fasteners and hidden install but am concerned about too much battery weight on one side washing my wake-love to see some pictures of everybody's set-up!

sailing216 03-31-2008 2:10 PM

Good topic. 2 Amps at 1650 watts and right now only one battery. I'm going to go to 2 batteries shortly. My question is it OK to have 2 different batteries? Regular marine for cranking, and optima for the stereo and should the cranking battery need help. What color Optima should I get?

05mobiuslsv 03-31-2008 2:16 PM

It's ok to have 2 different batteries if you don't ever combine them. Get the blue top, yellow top will work fine to just won't have the top screw terminals.

bkoz 03-31-2008 2:17 PM

Its ok to have two different kinds of batteries but from what I understand you just dont want to wire them together or run them on a switch at the same time, im sure someone will clarify. <BR> <BR>If I were to add a third battery how would I do it and still use my switch?

bkoz 03-31-2008 2:18 PM

See told ya someone would clarify!!!!

99xstar99 03-31-2008 2:21 PM

3 PDX amps....1600 watts <BR>1.1000 <BR>2 x 2.150's <BR> <BR>1 Kintetic 1800

denverd1 03-31-2008 2:40 PM

i will never pay for another optima battery. my .02. Too many other options these days. <BR> <BR>two types - but only charge one with alt. <BR> <BR>byron, depends on what the 3rd battery is for

acurtis_ttu 03-31-2008 2:42 PM

ideally you won't identical batteries ( same kind, brand, age) try and stay away from combining different kinds of batteries ( AGM, wet, gel) They all handle charges differently. It's just not ideal.

moomba55 03-31-2008 2:49 PM

So if you combine two different types of batteries and try to charge them both of the alternator what will happen? Problems resulting in the batteries or the alternator?

uofamox 03-31-2008 3:51 PM

3000 Watts RMS <BR>4 amps <BR>4 deep cycle batteries with total of 500 Amp Hours capacity <BR>1 starting/cranking battery <BR> <BR>I definitely agree you need to run the same types of batteries...wet cells and AGMs together most likely will cause issues or damage to batteries.

wake_upppp 03-31-2008 6:25 PM

1200 Watts RMS <BR>3 Amps <BR>2 Interstate Deep Cycle 850 cca's <BR>No Isolator or Perko, just a jump start box stashed under the seat that I've never had to use but other people on the lake sure have!

hatepain 03-31-2008 6:57 PM

2340 Watts with one cranking and 2 for the stereo but I'm looking at going to a 3rd for the stereo.

nvsairwarrior 03-31-2008 10:56 PM

Last year was the 3rd year running 4650 RMS watts with 4 Trojan T105 6V golf cart batteries. It's wired as 2 zones along with an on board charger (110VAC) that I always have pluged in if not out on the water. The batts are connected to a 2 zone Perko switch but I never select anything except "ALL" anymore. I did have a 130 amp alt (modified) but didn't hold up. Went back to the stock 60 amp and still have no problems while riding for 6-7 hours and or hanging at the beach with the system at some 1/2-3/4 volume for a couple of hours. For emergency I usually carry a portable 12V boost pack but have yet to need it. <BR>IMO the most important part of my power bank is the On board charger. It takes very good care of my batts despite frequent abuse.

acurtis_ttu 04-01-2008 5:52 AM

Duane, I exp the same thing. I have an onboard charger that stays plugged in while not ont eh water. My stock alt holds up fine. I've had issues with bigger modified alts int he past. <BR> <BR>Neal, The battery life will be shortened b/c the two diff. types of batteries charge at differnt rates, one battery will never get fully charged.

suprasteve 04-01-2008 8:27 AM

what size AWG wiring are you guys using to connect your batteries? I was thinking of using 4 AWG would be okay, but still pondering using 2 AWG. <BR> <BR>I'm going to run 2 AWG from the new (3rd battery) to the new zx1000.1 amp. <BR> <BR>Battery #2 and #3 will be on position #2 on the perko switch and then battery #1 will be on position #1. #1 will technically be my starting battery but i will prolly just leave the perko in the "all" position most of the time.

denverd1 04-01-2008 8:40 AM

Duane, I could not agree more. Plug in onboard charger (1 plug) and all 4 batteries are charged for next use. <BR> <BR>Neal, (to add to Adam's post) second, your alternator's will not last because it constantly sees two different charge levels and puts out different charge rates as needed. I'm also running a stock alt.

acurtis_ttu 04-01-2008 8:44 AM

Steve, there are charts online that will tell you AWG size needed by amps/cable length. One thing to note is that ther are alot of cable brands out there, some are not true 2/4 guage. I've seen cable labeled 2ga that when cut in half is probably 8 guage with a ton of insulation.

grant_west 04-01-2008 6:42 PM

This is a good question. IMO its one that has many diffrent answers. I will make up some examples <BR> <BR>A guy has a huge system with 2 Blue top's. And it works fine. He never plays it loud for very long just short blasts, and he dosen't have the bass up very loud or has no bass at all, or take in that he never plays the system for very long with the motor off. <BR> <BR>How many batterys you need can depend on #1 How long you like to play with the motor off, #2 What kind of music are you playing, Example a Hip hop song is gonna require more power than a rock song if you have a bunch of subs in your boat. Your power consumption is gonna be greater playing sertan types of music at diffrent level's and for what amount of time. My advice for people is have more battery power than you think your gonna need. Take you boat out a few times and keep track of your voltage you shouldnt dip below 12v if you are then you need some more power either a bigger alternator or more battery's or both.

Ben Kerran 04-01-2008 8:32 PM

I have always gotten by with just the one that came with the boat, but i don't like to play the stereo that loud.

bhutch 04-01-2008 8:43 PM

me too ben, also don't want all the extra weight in my boat<img src="http://www.wakeworld.com/MB/Discus/clipart/lol.gif" border=0>

deltariderscom 04-01-2008 8:57 PM

All I know is it is stupid loud when I am towing a rider and when I let off the throttle is gets quiet all by itself. The subs will knock your fillings out and there are 6 or 7 batteries to let it run a while.

uofamox 04-01-2008 8:58 PM

Yeah Ben's definition of not too loud is across the state of CA. I live two hours south and I think I can hear him from here.<img src="http://www.wakeworld.com/MB/Discus/clipart/rofl.gif" border=0> <BR> <BR>Ben, love the new profile pic. Where is that taken?

hatepain 04-01-2008 9:08 PM

By the picture it looks like 9 tens! Ok maybe not tens but pretty damn cute.

Ben Kerran 04-02-2008 12:09 PM

Gary- That is great (fillings out)<img src="http://www.wakeworld.com/MB/Discus/clipart/biggrin.gif" border=0>. I gotta get one of those volume controls from HSE. Are they out to the public yet or only you VIP's? Looking forward to 5/10 <BR> <BR>Bill- Yeah all that extra weight would only make my wake bigger and I fall hard enough as it is<img src="http://www.wakeworld.com/MB/Discus/clipart/happy.gif" border=0> <BR> <BR>Mox- It's at Berryessa. Thank god for my younger brother and his girl. I'm old and married and the wife doesn't like when I pull them in like I used to<img src="http://www.wakeworld.com/MB/Discus/clipart/rofl.gif" border=0> <BR> <BR>Seriously though on the battery thing. I have 10 blue tops and I run somewhere between 3.5 and 4K watts RMS (assuming everything is on). Grant is totally correct in that it really depends on type of music and volume. I can go from full charge to consistently dipping below 11.8 volts in 3 hours with certain music/volume. Or I can play 8 hours without my voltmeter even moving, it just depends on how hard I am pushing it and what type current the sub amps are drawing. I also have an upgraded alternator, so it is fine when the boat is running, but I usually leave it off when tied up for swimming etc.

deltariderscom 04-02-2008 12:24 PM

Ben and Coops systems are probably two of the best sounding and loudest systems I have heard. I have not heard "G"'s but seeing all the perfection work he does I can only imagine that the sound is as good as the install if not better. <BR> <BR>Ben; <BR> <BR>The official release date for the HSE volume control is June (father’s day). Production is in full swing and there should be 500+ units available then with more on the way. They orders are coming in fast for them so if you’re truly interested get one on pre-order. I know Neptune’s is distributing them but I am not sure on who else. <BR>I am super stoked about this season it should be of the chain. You’re going to be at Spring Ride this year right??? I am hoping to get all the LED stuff installed before then. <BR>We have a few trips to Berryessa planned this year so I will let you know and we will have to hook up. <BR> <BR>Best feature I added to the system was being able to plug it into 110V. So when I am on the houseboat and we want tunes I can play all day and night and run off of the 110v from the houseboat. <BR> <BR>(Message edited by deltariderscom on April 02, 2008)

Ben Kerran 04-02-2008 12:37 PM

Gary-G's system sounds absolutely ridiculous and is one of the sickest installs I have ever seen. It is even sicker because he did it all himself (with some help from Clay). We moved out to Concord a while back, and I recently moved the boat over to Orwood, so I am in your neck of the woods (now if I can just stop getting lost on the damn Delta<img src="http://www.wakeworld.com/MB/Discus/clipart/happy.gif" border=0>) I will definitely be at Springride and all the DRA events this year. I am looking forward to seeing everyone.

grant_west 04-02-2008 1:58 PM

Gary: I would agree with you 100% both Ben's and Richard's systems sound awesome IMO because they have the Bass to back up a strong tower. Most of these people with a HCLD tower don't have the bass to balance the system out. Sure they get the sound to the rider but it sounds pretty sharp IMO. <BR>True story: Ben's boat was down at the water at Tulloch. He was playing his system and he's system was shakin stuff on the walls at my house. I was like WTF is that?????? Who's system is that? I gotta check this out. I headed down to the water and thats when I met Ben. <img src="http://www.wakeworld.com/MB/Discus/clipart/happy.gif" border=0> a great guy <BR>Richard never play's his boat. Its like he's embarrased you have to beg him to to turn it on. <BR>He's like the quite guy in the corner and then when you get him fired up LOOK OUT! I know last year everyone was trying "Not" to play music because of the Sound Off and the DU contest so we gotta work somthig out. If you havent heard a big well put together system then your in for a treat. <BR>Cant wait get your Batteries charged up.

grant_west 04-02-2008 2:00 PM

I wanna hear Hammond's Tomcat. That thing should bang.

hatepain 04-02-2008 2:22 PM

Yeah, i'm bettin' that Eargasm II should be renamed Earquake after looking at some of the product he's got in that bad boy. I looked into the RE separates he installed in it and they look phenominol not to mention the ridiculous tower set up he's gonna be running. I was surprised in his subwoofer choice but they must be pretty good if he picked em.

Ben Kerran 04-02-2008 2:35 PM

Oh yeah.....Eargasm 2 in Stealth Mode. I'm stoked to check it out
