Hi Guys,

I'm a little new to the forum thing, but I'm definitely a big Toy enthusiast and will try to help how I can.

The factory speaker system in the 87-95 Runner's does incorporate an amp on each speaker housing. The amp can be used with an aftermarket stereo. You must be sure to hook up the amp turn on lead from your stereo (usually Blue/white) to the factory amp turn on lead. This is usually a solid white wire on the large plug at the radio location. If you are using an aftermarket wiring adapter harness, the power antenna wire will pin up with this wire. Otherwise, just tap onto it, and you should have sound. Be sure the rear speaker wires from the radio are connected to the correct rear speaker wires at the radio location (small plug).

Sorry for the long post, I hope this helps.

Darren
