So I just got a 12 inch dd 3500. It's hooked up to a kicker dx 1000 at 2 ohms (****** for this sub I know). I'm gonna try to get a arc kar series 1200.1 amp. Obviously it's an upgrade, but how much better will it power my sub. Will it be louder? Sound better? Or is it just the fact that it will be able to handle the sub at higher volumes? My local car audio shop told me that arc audio is one of the best amps you can buy. They just got some in yesterday and they told me they will sell it to me for 600 dollars. Will I notice the difference, I mean I understand you are getting what you pay for, but is it really worth the money?
