I have an Eminence Lab 12. I heared that LME 49811 can deliver 500 watts rms when bridged. I think 400 watts is enough. also my experience in electronics is not so good. (hobby circuits, dancing lights, dimmer tc) this kind of amp is my first project...............plz help meeeeeeeee

Even tho this is for a Subwoofer it will also give very respectable results if used as a main amplifier. See http://sound.westhost.com/project68.htm .

Save yourself a lot of time and money: http://www.amazon.com/Sony-XMZZR3301-Cl ... B001RBUHWM

You'll need a hefty 12 volt power supply capable of 50 amps or so - I'd suggest using a car battery on a trickle charger if you don't listen long enough to run the battery down.

600 watts RMS (330 into 4 ohms) for $120 ain't bad. It's only good for subwoofers though due to the extremely limited bandwidth.

Just a suggestion for a quick and easy way to "mega bass" for $120 plus an old car battery and a cheap DIY trickle charger. Just watch out for hydrogen gas accumulation. You might want a sealed battery for indoor use.
