Pioneer SA-1480 diagram

I have an old Pioneer SA1480 that does 130W per channel. Only does 2 channels.  Built 1987-88 era. Very little info on it out there. Has a built in 7 band equalizer.

I’m thinking of bridging the channels to drive a 15″ subwoofer  for my home system. 280W may do it. But I’d rather get 1000W, if possible.

If you need the schematics there are here.

    I had a similar dilemma with a project I was doing several years ago. Why not opt for a dual voice coil woofer? No mod’s would be needed for the amp and you’d have lots of power! Just a thought.
