Hey guys. So I have active speakers and I bypassed the one stock amp in the rear using this method.
Successful S13 rear factory amp bypass: Nissan Audio / Entertainment / Security: Nissan Forums / Infiniti Forums - NICOclub
Took out the whole crappy amp.
After I've done all that, the speakers make a noise whenever I turn the car off.
Here's a video of it.
