Audio Systems: what amplifire do i need?, deep cycle battery, watts rms


Question
i have 4 15" 4 ohm ,solo baric pic holds 2000 watts the rms 1000  what kind of amplifire do i need to get the max out of them?

Answer
A mono amp that's 4000 watts RMS @ 1 ohm with the subs all wired parallel.

Side note:

Running that much power will require you to:

1. Upgrade the alternator to a high output alternator
2. Upgrade to a heavy duty deep cycle 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 0/1 AWG wire.

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

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.

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.
The alternator must have at least 20% more amperage power than the entire vehicle and sound system combined for a cap to be of benefit which is ironically the same requirements for an amp to be efficient.
