well i've pretty much narrowed my speaker problems down to the amp but now my problem is finding another one. so far my available options are 1) get a new radio, amp, and speakers while rewiring the car. 2) call around to all the junk yards and see if they have any nakamichi amps for the sc. or 3) pay lexus 1400 dollars for the amp. if you guys have any suggestions on which route to take please let me know, specifically on the first route which is what i'll probably have to take. what kind of after market audio parts have you used and had good success with? thanks for your help.
