ok so im planing on installing my own system into my 99 grand prix, i have a box layout and i know which sub/amp im going to buy. I need help on a lot of things with this build like, will i need an alternator? will i need an extra battery? (only poweing 1 15in sub and 1 AQ1200d amp). Also im not too sure how i should set up the sub in my trunk, if u guys need pics plz tell me and i will get them for u. I also need to know what type of wire to buy for the AQ HDC3 15" copper coil series sub, and anything else u think i need to know about this, PLEASE tell me
