I've been shopping around to replace the Monsoon, and I've noticed that the sales people don't seem to know where to put the new amp. Has anybody replaced their Monsoon system component for component (No new subthumps, or anything to screw up my T-top storage) and found a home for a new amp? One suggestion was under the passenger seat. How about some input, please. Oh, I want to put in an Alpine hu, and haven't decided on what amp or speakers quite yet, but I want to use the same speaker holes. Help!
