I got the sub and amp install... sounds pretty good except for my trunk lid rattling at the bass level I want. I picked up some dynamat and will hopefully install that soon.

Instead of a crossover I have been glancing at some equalizers. I was looking at some AudioControl EQTs because I have heard some good things about them.

Then tanstaafl, are there any good reference books/manuals that explain how to tune for an IASCA competition? (other than the iasca handbook)
