Which amp?!?! Rev 8's
 
Hey guys, I have been a lurker for quite a while and have never needed to post anything that I couldn't find out by just searching... Well I have been searching, reading, searching for over a week now, and I figured I'd finally just ask for some help.

I just got a new pair of Rev 8's thanks to the great fella's at Wet Sounds (Tim and Robert). I had a pair of Pro80's that were powered by a Cadence TXA-3004 bridged for 300x2 @4ohms, but after about 4years it has died on me...

I need something to power the Rev's but I really don't want to spend over $200 on another amp.

I currently have the 5 channel Fusion marine amp which are powering 4 polk in boats and an Exile 12. I wouldn't mind getting another Fusion, Cadence, or really anything that is decently cheap and can still throw 300+ RMS at these guys.

I have looked at the Cadence D100.4 or fxa-4100.
I also like the Fusion CA-DA41400 which says it can do 440x2 @4ohms.
Last but not least, the Exile SM400.4 400x2 @4ohms. (leaning towards this one atm)

I know this topic has been brought up several times, but I would really appreciate some opinions before I pull the trigger.

You need to go by the amp's RMS output and not the unrealistic peak output. I would also suggest a Class-D or G/H as opposed to the less efficient Class-a/b. The consume less battery Ah then an A/B amp producing the same watts rms and are typically smaller. I can tell you with out a doubt, that one amp in your list does not even come close to producing that stated power. Not familiar with the specs on the first two.

I've got a pair of rev 8's powered by one of these http://pages.ebay.com/link/?nav=item...d=321122880676
They are clean, clear and loud.

Myles,
One pair of 8-inch HLCDs can be enough. But to reach their full potential you need the right power.
A common amplifier packaged with the Rev8s (one pair) is the JL Audio XD400/4 bridged. As independently tested it will deliver 2 X 200 watts RMS even with a 12.6 volt supply....which is far less than the 14.4 volt supply at which amplifiers are typically rated. The XD400/4 is actually 2 X 280 watts with a 14.4 volt supply. So it has the power even with a lower supply voltage, is a highly efficient fullrange Class D, and is exceptionally clean. Now, you can get all the same attributes in the Wetsounds line-up with a bridged Wetsounds HT-4. There's no need to look outside the of Wetsounds.
In reality, a couple of the other amplifiers mentioned are not even in the same ballpark, not to mention inefficient Class AB.

I am aware that I will need at least 300 watts RMS for each speaker and I would definitely prefer a class D amp to help out with power consumption.

That Precision Power P900.4 looks nice on paper and the price is right.... I like the Exile one but it is class a/b...
I also really like the Fusion CA-DA41400. It's a class D and puts out 440x2 RMS. It looks just like my 5 channel Fusion marine amp, and I'm really happy with it.

Thanks for chiming in David. I've already learned a lot from reading through your posts. Thanks for your contribution to this and all of the other forums!... My main concern other then making these bad boys scream is cost. I really can't afford to throw any more money at the boat this season, and by that I mean my wife wont let me :o

I know you get what you pay for, but I just can't afford the Wetsounds amps. Could I get away with a decent class D amp that is rated over 400w RMS and just except the fact that i'll probably only see about 80% or so of the RMS rating?? I just need to get through about 2 seasons and then I plan on upgrading the boat...

I am running a HT-4 on mine and they sound great. Almost too much, if their is such a thing!!

jonblarc7 07-25-2013 6:33 PM

I got the PPI 900.4 on a pair of Rev 10s it sounds real good.

stevev210 07-25-2013 6:33 PM

Not to hijack but what would be a good amp for 4 rev8s?

chpthril 07-25-2013 6:47 PM

Steve,

Out of the Wet Sounds stable, the Syn-2 is a solid choice. The SD-2 is a strong option and a pair of HT-4 is worth a look as well.

boardman74 07-25-2013 7:49 PM

Pair of HT-4's would do great. I have one set off a Ht-4 and at 300 each they really scream!! I kicked around alot of options and am very happy with my choice.

stevev210 07-25-2013 7:54 PM

I am currently running the syn2 and they sound great but sometimes wonder if I'm giving them adequate power. Do you think wetsounds is a bit conservative on numbers and there's more power then actually stated?

BradM07SS 07-26-2013 3:12 AM

I have the PPI 900.4 on my rev 10s and love it. Cheap small and powerful. It's takin many 6 hour blastings partying.

racer808 07-26-2013 4:53 AM

Precision power p900.4 as stated above is an awesome amp. I run the p900.4 to my pro 80s a p600.2 to my mb8s and the p900.5 to the interior and sub. My system is loud and clear. The amps are class d, very light, use little power

DQ 07-26-2013 6:43 AM

I have a Cadence ZRS9004 that is in great condition I will sell you. Let me know if you are interested. Will get you 250 to each speaker. I actually bought it from Wet Sounds a few years ago and it sounded awesome on my Pro80's. I have since upgraded my entire system and it is just sitting in the house. Was thinking of putting it in my truck but will give it up.

Brearly_Mason 07-26-2013 10:27 AM

What about the Alpine PDX 4.150. I have two of these and was hoping to run a pair of REV 8's on each amp. Will the Alpine PDX 4.150 give enough power for REV 8's?

DQ 07-26-2013 10:30 AM

It shows that the PDX 4.150 bridged into two channels will give you 300 watts to each speaker. That power would be great for them.

chpthril 07-26-2013 10:47 AM

Steve,

The Syn-2 for 2 pair is spot on RMS power, but yes, they will handle more. If you seek a seas-of-the-pants difference, you are going to have to significantly pump the RMS to each. A single SD-2 or a pair of GT-4's.

Im running 2 of these on 4 rev 8's and it is clean. sounds great

liquidr6s 07-26-2013 3:23 PM

Chris- You're running 2 of which amp?

DQ- Thanks for the offer but I think I want to throw more then 250 RMS at them.

I'm really liking the feedback I'm getting on the p900.4. I think that might be the winner as of now.

nitrousbird 07-26-2013 5:04 PM

I am running the Polk version of the PPI 900.4 (the Polk D4000.4). Great amp, go for it. You aren't going to find a better bang for buck amp than that PPI, period.
