I don't think I would buy them for .01c... Who wants to spend money on taillights that look cool to people eating your exhaust. Just my opinion...I know this is off topic but....
SVTweeter...I have 3 10's on an original punch 100...I do have goodies like audiocontrol x-over, stinger 2 awg, optima red top, but don't you think your 4 15's should pump out more then 148db?...I know 148 is ALOT but I am pushing low 146's with minimal tuning and crappy MTX subs (i did the install and everything myself, including box building).. Did you install and tune yourself? Did you test with bck seats up or down?
