I have 2 12" Pioneer TS-W308D4 and 2 12" kickers cvr could i have all 4 subs to a kac-9104d amp?? How?

wire both the pioneer's in parallel, and the kickers in parallel uming they are D4 as well. each pair will total 1 ohm. a 9104 does it's best at 2 ohms, so from there wire each set in series to bring the total up to 2 ohms. and there you have it. i dont really recommend using all 4 since the amp can't push that much power. its handles about 890 watts. your gonna hook like 1600 on it... the amp will run at it's max the whole time and overheat. i deal with these amps everyday at work.
