I have a 12 inch infinity sub

What amp should i get for clear bass sound and clear sound in general

 

one that does about 500rms into a 2-Ohm load

 

say my budget is 200 bucks watts the best amp i could get to power this bad boy

 

an alpine mrp-m500 would fit the bill nicely.

There are some good sales on amps in the classifieds that would do the trick as well. This one has 2 that are in your budget and would work well
