Started on my new install for the 2007 season and just got back in from 3 hours sitting in my truck and listening to my mids in all kinds of locations.
I was really wanting to go with the dash but I just couldnt make them work. After hearing all the great sounding systems at finals with dash mids I was sure it would work but I rekon with my 40 acre windshiled it was just too much glass and reflection to EQ out.
It did require a lot less volume to crank em up and everything was very nice and high but everything just had a harsh, metallic sound to it. Plus, it wouldve been a pretty big chore to get them to fit up there.
So I decided to go with the kicks but, oddly enough, the angle that worked best was with them firing straight back to the rear of the truck. I tried them firing straight across and at the opposite head rest at varying angles but them firing straight focused up the image a lot more.
The downside is that it dropped the stage. It used to be about 6" above the dash, with the mids in the dash it was eye level. With them in the kicks its barely above the dash at all.
Ill have to play with crossover points and phasing and maybe I can get that fixed but Id give up some height for a better focues image.
So now Im off to Home Depot for some supplies and then to Radio Shack for speaker wire and then Ill get to it.
Ill be the only guy with custom kick panels made 100% out of MDF! :D
