I'm looking for a good head unit and or a nice 500 watt amp that will knock my car. I dont know much about car audio, or exactly what im looking for. I have a few things things that i could trade, and i could throw in a couple of $'s if needed. But currently unemployed, so i cant pay 2 much extra. I have 2 10" jensen speakers in a dual sealed box, and i also have a dual 12" box. the speakers are in great shape, and havent been used for more than a month. Boxes are both sealed and are carpeted. Please help me out. I have a crapy a$$ car ( 89 mercury topaz //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif ) and i at least want to have a knock in it. Right now i have a factory head unit, an 1/2 blown power acoustic amp, and a 12" RF XLC. It has a little knock right now, but i want something that you can hear outside the car, as well as inside the car!! You can reach me on aim at redxtc420
