I need a good amp that will do 700w @ 2ohm or somewhere around that. The more power the better in case of future upgrades. Budget is around $150. I know I wont get anything top of the line for that. I just want a decent amp.
Not sure about your price range. You might be hard pressed to find an amp that will actually produce 700 rms at 2 ohm for $150. A good amp to maybe consider is the Kicker 750.1, even though it will be more than $150.
very tight budget. the audioque AQ1200D will give you a clean 600 watts @ 2 ohms and 1200 @ 1 ohm you won't hear the difference between 600 and 700 watts. You'd have to double the power to even get +3dB difference. Double the volume would be ten (10) times the power from the amplifier.
