i have 2 cvrs 15s being pushed by zx750 amp.

i planning on getter 4 5by7s with a mtx thunder 4 chnael amp.

should i get a capatier?
 
if your headlights dim when the bass hits then a cap will help out. it stores energy much like a battery does and when it sees a voltage spike say when a bass note hits, it releases that energy to help keep the line voltage up. it has a much faster recovery rate than a battery does. a good rule of thumb is.... for every 1000 watts = 1 farad of capacity. check out my profile and my source
 
Yes it will help the batter life and alt from dieing sooner than you would like them to.
get the bigger the better...

i have 2 amps and (the Cap) 5 farait running my system with a optima battery and a 150amp alt ... so with your system i would get no questions.
 
NEVER listen to someone that can't spell Farad...

A capacitor is only good so far as the audio system isn't trying to pull too much from the electrical system. A cap doesn't provide more power, it's designed to 'stiffen' the voltage to the amp, nothing else. If the current isn't there, a cap won't help.

If your total system power is 1200 watts RMS or more, you will need to:

1. Upgrade the alternator to a high output alternator
2. Upgrade to a yellow top battery
3. Upgrade the "Big 3" - that is to replace (or add to) the power wire between the battery and alternator, the ground from the battery to the chassis and the ground strap from the engine/tranny to the chassis with at least 2 AWG wire.

Failure to do this will result in the early death of the alternator as it will eventually fail.

Here is a guide that will calculate what size alternator and power wires you need http://www.box.net/shared/uchv4dbk88

You will need Microsoft Excel. If you don't have Excel, use this link http://www.box.net/shared/nkkw1dhk4g

A second battery is never a good idea as it's an added strain on the alternator to charge two batteries AND supply power for the car. The ONLY time a second battery is useful is if the audio system is to be used with the car off.
