2 10's is the way to go IMO. This way I dont have a 10" working its butt off. Easiest way to think of it is that 1 have a 20" speaker because I am runnig both in mono ahahaha. I listen to more rock and country than the boom boom. They hold their own on the bassy stuff though. I hope you are going to post pics. I had two shops here look at the install and asked what they would charge for it. (needed to get apraisal for insurance anyway). Both said around $500. That is just for fabrication and electrical install, not including the price of the equiptment. I am definately in the wrong business haha. And if you don't mind a around price that they charged you.

 

Here are pics of the "push/pull" fans and the LED bar.
