800 watt RMS amp at 4ohms? +Rep

Anyone know of an amplifier that puts out 800 watt RMS (or close to) at 4 ohms?

Thanks! And +Rep will be given to answers!

define NEED. are you doing comp, or do you just want good bass?

if you already have an amp, i would hook that up first, and once you have everything sorted out, see if you want/need more. i think you'll be ok as long as you know the limits of the system and don't clip it and push it harder when it distorts.

i'll let someone with a deeper knowledge of car-specific applications get in here, my knowledge of amp/speaker combos is more on the PA/live sound side and probably does not apply here.

I wont be doing competitions, but I do want some good bass. I already have the amp, but I just dont have those subs. I would like to get them tho. With the amp that I have, I could probably turn the gain up more tho. And since they can handle 800 watts RMS I should be fine... right?

As long as you don't max out the gain on your amp and make it clip you should be fine. As soon as you hear clipping, back it off a bit, otherwise you run the risk of overheating your subs and burning them out.

You don't need 800WRMS to get good bass. I'm pushing less than half that and I'm satisfied, even with the wrong box for my Inifinity Kappa. This is just all my opinion, though.

Actually you shouldnt have to change the gains at all if they are already set correctly regardless of what subs you are running....gain is not used to adjust power output its there to match your voltage up with the rca outputs

Yes. 800 Watts RMS can be extremely loud especially in a focus. You need to look at amps very closely. There are multipul classes. Most amps are class AB. This means they don't actually produce the power they say they do. A 400 watt RMS class AB amp with the proper wiring only produces about 200-250 watts RMS. You want a Class D amplifier. They are more expensive but much much much more efficient. A 400 watt class D will produce between 350-400 watts with the proper wiring.

Don't by from Ebay because you won't have a warrenty and you never know exactly what you are getting.

The enclosure also makes a huge difference. A sealed is more quiet but often more clean. A properly tuned ported box can sound great and be very loud with minimal wattage.

Get something class D from a reputable dealer like crutchfield and install it with the proper wiring and you will have more than enough bass to make you happy.
