I took a look today at how to mount. The dash slopes WAAAAYYYY underneath, and it would aim directly at the steering wheel/crotch. I'm thinking on top of the dash would be a little much. I have been thinking of 3 way (woofer in doors, 8" if it fits, 3.5" in dash and tweet either custom mounted in dash or in sail panel.

I think by far the absolute loudest and clearest components are MB Quart they have been around for years they are tried and true. There is a reason they are still making speakers for all these years. The same with subs go with what has worked JL W6 series nothing can compare to the range of bass you get from them. The same for the Quarts they have outstanding range and they won't crackle if you have you stuff set right and matched properly. Use good wire everywhere your system is only as good as its weakest link you could spend 1500 on the world's best speakers but if you buy a cheap amp or use scrappy speaker wire. The system will never perform or sound the way it can. Good Luck and have fun
