Batteries and amplifier hook up help!
 

I just purchased a 2008 Bayler 195 F 19. I know my basics when it comes to hooking up sound systems and actually know quite a bit, but now with this boat, i want to be able to power the system while the boat is off and not drain my battery. I want to have the original four speakers that are in the boat still hooked up. I ordered the tower speakers, the Kicker speaker bar which has 4 kicker speakers on it. And also want to place two 12" subs on the boat as well. I will be running it all through a 2000 watt amp. What do i have to do, to be able to run this system, without being stranded at the sandbar with a dead battery!? I do know i might have to add a battery or two, so any help on wiring them together would be great!

Blue seas add a battery kit. and you're done. schematics come with it. basically has a relay that looks at the incoming voltage if it is around 14amps (meaning your alternator is on) then it charges both batteries. if it isnt it isolates your house/stereo load from your starter battery. ensuring you will always have a starter battery left to get you home. You can also combine the batteries. So say your starter battery goes out you can combine the batteries and use your house battery to start the boat.

That simple huh? Is this the right thing i am looking for?

Sorry i guess the add has expired or something, however i purchased it there was only two to select from so hopefully it works, thanks for the information! Is there anything else i should know when i start to hook this system up in my boat that anyone could fill me in with before i wire something wrong? haha
