I am looking to make a new system on a budget with one alpine 15 type r in a custom box and I think I am gonna go with a cheaper amp. I was looking at the hitron hpa2000.1D and the lanzar maxp1200. I know they are cheap amps but do you guys think they would push it well enough? Any suggestions for amps would help I'm just trying to find some that would work well for hopefully under 150. But if I would notice a great increase in SQ or even SPL then I guess I could spend the money for it.
