Does anyone know if Sound Storm provides a good Amp worth buying? I was just looking at the F500.2 model and wondering if it's any good. Never had heard of the company before, then again i'm wet behind the ears when it comes to car audio. And would this be a good amp to run an Audiobahn Alum15X 15" Sub? (Is the ALUM15X a good sub?) ... Any input would help. Thanks.
