ok i so i got the infinity ref6020cs comp. speakers. so im just trying to figure out whats a good amp and sub would be to compliment them or something. but before i get bashed on those speakers reason i bought them was because they were real cheap. i could also get an alpine 1242 sub, but is that s good sub? or are there any better for the same price range. back to the main question....im looking for a sub that can hit but at the same time not overpowering i kinda actually wanna hear the music not just a bunch of bass. and i would like to know some recommendations on amps, i was thinking one to power the front speakers( set of comps. and coaxials rears) and one for the sub.
