Ok here guys I really don't want to spend more than 150 shipped on an amp wether it can run at 1 ohm or 4 ohms bridged my subs are 350 watts rms a piece so i say give em 300 to 325 rms. So with that said I need an amp to do 650 or 700 watts rms at 4 ohms bridged or at one ohm mono. Ill got out and measure the room I have for the amp to be mounted.
