Hey guys, i've had my P38 for quite a while now. It has the original speakers (no Harman&Kardon) and it has an aftermarket head unit. Now i want to replace the speakers because they really have seen better times. Anyways i am wondering if it is even necessary for me to get a new amplifier or if the amplifiers that are installed at each door are good enough for the new speakers. If i should install a new one, has anyone of you guys figured out a good place to put it?
