Depends what amp you are running now. I have 1 set of the T165 comp left and I'm giving them round 100 watts each side

Had them on a PPI PC450 and they did great. T165's sound good at 75 watts

I can't tell you there would not be an audible difference, but you have a good amp now. If your music collection has been hand picked for excellent dynamic range, which most people don't do, then maybe you would hear a difference if you doubled or tripled the power. That extra power is for transient peaks. Pop music has no peaks, it's all loud, so the extra power would go to waste.

Are you only using that amp to run one set of components (Rockford fosgate T165s)? If so, why don't you bridge the amp and you will get 150 rms x2 and you can keep the gains down. The extra distotion from bridgng will not be audible at all

I was thinking of just putting rears in the other 2 CH would I be better bridging them and would that hurt the speakers at all and how would I do that
