First system needs a 4 channel amp, main points are size (small) and SQ, speakers will be Focal Is200's. Looking to spend about $250 on it.
Second system will be 2 JL W7's, don't know much about the setup as it is a friends car, he has a hifonics amp powering them right now, and in all truth it sounds like ****, he had a 15" L5 or L7 before. I believe he said it's a 1200 or 1500W amp, sorry I don't know the model. Price...I am not really sure, he told me he was pretty open.
