I have used MA audio subwoofers now for a while and they have done nothing but please me. I had one MA Audio HK15X2 hooked up to a rockford P550.2 for a while and it was loud!

I thought I would kick it up a notch and now I am going to put another hk15x2 in, and I just got a MA Audio HK802SX 4400W RMS 2 Channel amp.

I have a high output alternator(about 160amps) and a redtop in my 96 Toyota v6 Camry and the big 3 upgraded with 4 gauge.

I need some advice on how many wires to run, how many extra batterys I will need, and anthing I might need to know about running such a big amp.

I wouldn't worry about it. It isn't 4400 watts. Don't argue - IT ISN'T! If you get an honest 1200 out of it, I'd be really surprised.

That being said, 1200/.6=2000 2000/14.4=139A 139A can be safely carried by a single #4, fused for 150A (NO BIGGER).

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

I would use larger wire for the Big3. 4g can only carry up to 150a, and your alt is 160a. Now, I know the alt won't always be putting out that much (if at all), but it's best to go larger!

MA and Audiobahn both use "RMS".

Rediculously Meaningless Spec.
