Lets say i got Infinity Kappa Perfect 6.1 6-1/2" Components and Infinity Perfect 10DVQ DVC 10" Die-Cast High-Output Subwoofer and some sort of HU (Alpine 9831,9833, or 9835). Links

What sort of amp would i need to power all of this? Thanks

 

An amp thats 125x4 @ 4 ohms would be ideal (or 2 amps at 125x2 @4ohms each)

 

what about if i opted for the Alphasonik PSW810 instead?

400-500 to the sub would do you well.

 

got any specific models i should look at?

 

Budget???

 

preferably around 300, around 400 if need be

 

Do what I did, get two of the same amp.....

One for the speakers, one for the sub....youll have a great system, and amps you can use for other things besides subs.
