 How big of an Amp do I need?

So this question is for anyone who knows about car audio systems. The Subwoofer I'm getting is Dual Audio SBP10 which has 750w (375rms) 4 ohms. I'm sure it isn't the greatest one in the world, but it is coming with the box I want so I'll just use it until it blows. So as much as I appreciate all advice, I don't need any advice on the type of sub I'm getting please :) Anyways, I'm wondering how big of an amp I need to get. Like a one channel that does 375 rms, or 2 channel that does 175rms or something like that. Any help would be greatly appreciated! Thanks!

Any amp that puts out 400w at 4 ohm will do well look at a 2ch amp that will bridge to that it will most likely be the most cost effective

any amp will do whether it's a mono or 2 channel amp. Just look at the 4 ohm rating for the mono amp. For a 2 channel amp, look at the bridged rating. As for budget, you can go with a power acoustik or Hifonics HFI line. You should probably shoot for around 400-450 rms watts. Easier for an amp to produce adequate sound levels when you slightly go over the power rating of your sub, that way your amp doesn't have to work as hard and you won't risk cranking up the amp gain in order to get louder!

Yeah, just a basic mid-size 2 ch that bridges to 350-400w rms.
Since you don't have the greatest sub, you probably don't want to spend a whole lot on an amp, so here are a few possibilities:
