Thank you very much for all the help but in the end i didnt really need a pre amp, i needed more of a source of power for another amp i had. I used an old power source from a desktop computer lol.
I have a 2 channel 1300 watt amp pushing 2 D9 vegas for the front I have an additional amp pushing back speakers. What do I use as a pre amp to achieve at least 5.1 surround
