dnewma04 - that was a very nice break down. Sounds like you know your stuff.
I personally live and die with MTX and Infinity.

dnewma04- I was thinking about adding 6x9's to the back dash of my tour. what do you think? currently i run 2 MTX 6000 subs (12in) and Infinity Kappas in the doors and power them with an old stlye two channel amp (Mtx) and a JVC hu with 45wats. should i do it? If I do, I wanna dynomat everything. Have you tried that? Is it hard? I would be doing all the work myself. Thanks people!

Sorry this is soo long.
