Car amplifier at home (diy)

i've got a small project going on at home for hooking up my car amplifier and subwoofers in my room. i'd like to ask for a bit of help in making sure my circuit will be okay and a bit of help in making sure i get the right power to the system. what power source in my at home area would you recommend, and can you check to see i've got the correct equipment?
for the power source i was thinking of an `adc convert 3000 watts`, thoughts?
this is what i'm using:
(1) x2 subwoofers xfire xfr 12" (*specs below)
(2) x1 amplifier 2400w memphis srx 1200d.1
(3) x1 ren20kit 4 guage

I can't help with recommendations but I'm sure glad I'm not you neighbor!

What is a "adc convert 3000 watts" and asking what is available in your home area means nothing to a World Wide forum. We have no idea which stores or suppliers are in your locality or indeed where you actually are.


Brian.

On the other forum I said that the 12" woofer has a resonant frequency too high to be a sub-woofer and the amplifier has an output of maybe 300W into each speaker's two paralleled coils.
The ebay no-name-brand speaker and amplifier junk are missing many detailed spec's which are probably exaggerated.
I agree that you need that extreme amount of power because in your car it deafened you.
