Hi, I have a 400 watt pioneer amp that I use in my home thertre system. It is hooked up to a 12" sub, I used to have a shitty 400 watt PSU hooked up ot it which was barely sufficient. After having enough of not being able to turn it up too high I decided to get a new PSU. I went out and bought a 500 watt psu which gives above 380 watts on the 12volt rails. The existing one was giving about 300 watts ish. I was wondering if there was anyway that I could hook both psu's into the one amp. Keep in mind that I have cut all the yellow and black wires and hooked them into the positive and negative terminals of the amp.
