01 v8....Ok so I've been wanting to put in my subs but I've been procrastinating too much. I had to jump my buddies car the other day and realize I forgot my battery is in the f'ing trunk!! (I know I'm a genius ) lol...so correct me if I'm wrong all I need to do is run the power wire about 2 ft down to the battery and run the rca's up to the factory head unit. I've never ran subs off a factory unit but I believe I have to buy some kind of adapter? I also wanna put my 4 channel on the interior but I'm afraid I can't do that myself with the factory amps already there and what not. I got the alpine 6 disc system any advice is appreciated.
