Advantage disadvantage of using a battery
I've seen set ups with batteries sitting in the back... is that to power the amp instead of using your regular battery?

RE: Advantage disadvantage of using a battery
Sometimes people put the battery in the back to move the weight distribution towards the rear of the vehicle. I guess you could use a battery in the rear to power an amp too, but you'll have to run wires from the alternator to the battery in the rear which would be just as much hassle as running wires from the battery in the enigine compartment to the amp in the rear. Unless you're looking to improve the handling of your truck I don't really see any reason to move the battery to the back.

If you've got hydraulics you'll need a bunch of batteries and there's storage space in the rear for all those batteries, I guess that's another reason for putting batteries in the rear. Keep in mind you'll need a larger alternator if you plan on having more than one battery in the truck, or you'll have to plug the auxiliary batteries into a charger when you get home every night.

RE: Advantage disadvantage of using a battery
Well thanks. I got another question... say I have 2 1200 watt subs and a 1600 watt amp... Would I need a new alternator thats cranks out more than my 105 amps?

My dad's benz has the battery in the back, just because it's a huge battery and there's not much room in the engine compartment for it, and also for weight distribution.

RE: Advantage disadvantage of using a battery
Your car will run with those amps on a 105 amp alt. but you will have a voltage drop and every light will dim when subs hit. You could look to get a stinger, or ohio generator alt. but look to spend around $400-$500. Or look at doing the big three..

also many people will have multiple batteries and alts. in a setup so they will give more power and be able to run there car without light dimming. Its more power out of another battery then using a cap.

RE: Advantage disadvantage of using a battery
You could also just run a capacitor on your system, that is the easiest and cheapest solution to your problem, it levels out the electric charge and doesnt drain your battery nearly as much, would make your system much better. For that much wattage, you will need a good 1.5 or 2 Farad Capacitor, but sure beats more batteries or a $500 alternator.

RE: Advantage disadvantage of using a battery
Thanks alot everyone for your help. I like the capacitor idea. I'm just nervous because one thing that happened to me was I let my brother use a couple of my older 12's with an mtx amp when he went up north... Well he came back and I put em back in and somthing wasn't right... My ground wire melted some of the plastic that is was touching on the bolt it was grounded on. I couldn't figure out why... I looked at the main power wire and he blew my fuse and put a straight 4g peice of wire in between it so it had constant power... And I don't know if this is why but after that my alternator fried(I don't think that was it but hey... it worked fine before) and my battery was dead, just not pretty. Well I took the subs out and haven't put em in yet. But thanks for all your help.

RE: Advantage disadvantage of using a battery
capacitors are rated in RMS power, so if your amp is say 1000 Watts RMS, then you need a 1 Farad capacitor, 2000 Watts RMS is a 2 Farad. A 1.5 Farad capacitor should be more than enough if your amp is 1600 Max, 800 RMS I'm assuming.
