If you're installing new speakers in a car to upgrade from stock, should you absolutely install a new amp? I installed a Kenwood head unit a while back with no problem, and I'm tired of the sound quality of my stock speakers (06 WRX) but I'm not sure whether I'm ready to start screwing with my battery cable.
Pic somewhat unrelated.
