OK, I do not know much about car stereo systems, although I do know what sounds good. Here's what I want: a moderately priced system that plays country, rock, and hip hop well, with a lot of adjustability. All my friends have either JL or Kicker L7 subs with an amp, but thats it. I want to replace all the speakers in the K5, add a few, and put in a nice headunit and amp. My question is, can some of you that have been around audio awhile help me out with what I should buy? I don't really trust the salesmen down at CustomSounds. I know I want to put my sub on the inside of the rear quarter panel, maybe have some 6X9s back there too, and replace the speakers up front. Here's what I want: 1.A higher-end headunit with good radio reception, (I use my iPod with iTrip alot, basically no CD's) and alot of radio and sound presets. 2. A nice 12 inch subwoofer, loud but clean. 3. A nice amplifier that can power the sub cleanly and easily. 4. Replacement speakers all around. Can yall tell me your recommendations for 1-4? Any help is appreciated, and keep in mind, I'm a high school kid, not an audiophile, so keep in mind what you wanted back when you were 16 . I was hoping to keep all the components cost to $1000 or under, is this possible? Thanks for all your help!
