ok so im planning on buying a 1991 cadillac fleetwood next month, but i wanted to buy the sound system for it this week. im not too informed on the "tech" stuff so i wanted to ask people that know. i DO know that i want to get 3 15" L7's, but i need help on picking out the amp for them. what would give me the best performance.also what speakers should i get for my mids and highs. one of my friends said it would be pounding so hard that its best to just get subs and lots of tweeters but i dont know. i want to enjoy everything not just the bass in music. thanks very much in advance ittl help alot 
by the way, is there anything i can do to take that rattle ill have from my truck to cease?
