How can you run two amplifiers off the same battery?

Question

i want one for the sub and one for the speakers....so how can i do it?

Answer 1

Listen to Jeremy. The crossover - if you use one ["should you accept this mission 007"] - needs to go before the amplifiers. Also check your levels. If you are going to drive two amps from one source, look things over. Your input impedance to the amps should be infinity. But if you run them from one output then the effective impedance will be halved. You should still be okay. I'm just thinking as I type. If you have a line out from your head unit, use that to drive both amplifiers. If you use speaker out, you'll easily overdrive the inputs to the two amplifiers. You can do it but you need to be careful. Check the maximum input level allowed for your amplifiers if you do that, and you don't want to exceed that (input level). You can email me if you get tangled up.

Answer 2

It's no different than running one amp. just run the power to it.

You can also use a crossover to send the lows to the sub amp and the mid/highs to the other.

Answer 3

you need a distrabution block, that turns your main power wire in to multiple power wires so you can hook up multiple amps. same for your ground. as far as rca's go you amp should have a line in and a line out. hook up you line in and then the line out into you other amps line in.
