So at the moment i have two doors and two rear decks running off of a 1000c4 crescendo audio I also have two alpine type r's running off it. Yes i know lack of power, so for now i just got the doors and rears running off the head unit to give power to the subs. My question is that i wanted your opinion on these two amps MB Quart and this Audioque. which one would you guys choose? also I am running this system on a 2004 grand prix with a stock alternator (105 amps) do i need to upgrade this at all or should i be fine powering these two amps on stock electrics.
