I am not trying to have a go at anyone, but I just have not seen fusion perform. If its the right price yeah go for it. I am not at all trying to say i have the best stereo around, no where near it, but for example, the Fusion WRX just made 140 db with 3 15's and a hell of a lot of power at the 2003 jamboree. I would have thought it may have performed a little better.
My car got 148 db with two 12's at jamboree, and i had a few bugs that i have been iorning out.
Honestly good luck man, i hope it all works out!
Happy Stereo-ing
