OK currently I have a 10" kicker sub capable of 300watt RMS bridged to a 150watt kicker amp. I'm planning on upgrading my system with a big check I'm getting. I'm thinking of buying a rockford fosgate amp and possibly sub. What is everyone that knows about car audio's opinion on kicker and rockford? Which do you think is better? Should I just get a more powerful amp for my kicker sub? Should I get a kicker amp again? This sub is in an extended cab pickup btw sitting on the back seats in a small nonported enclosure. Would upgrading the amp make the sub sound any better?
