i'm planning a sound system for a C5 coupe that will involve two alpine MRP f450 amps (front and rear speakers) i'm thinking about building a custom amp rack that will have each amp mounted at an angle behind each seat. (really like idea of using a plywood base to mount the amps on and epoxying it to the car)

any advice or pix?

 

i wouldnt epoxy it to the car unless that was my last resort. if you're going to have the amps directly behind the seats then i probably would try to see if there was a way i could make the board in a lazy 'l' shape (to follow the contour of the wall behind the seat) and then see if i can mount it using the existing seat bolts (maybe get some longer grade 8 bolts an a metal strap to secure the bottom part of the 'L'. doing it this way you dont have to worry about supporting downward force because the floor of the car will do that, and then bolting it to the existing seat bolts will take care of lateral forces and keep the amp rack in its place. i'm not sure if this could be done...but worth looking into. onther option is to silicone or liquid nail a piece of wood under the carpet against taht vertical wall and then use that as a base to mount the amp rack to. this way it can be removed further down the line.

if you are talking about the area behind the seats....in the 'trunk' area. if you have a vert you can get away with a friction fit since you have the waterfall to protect youfrom flying amps in the event of an accident. if not, apply the silicone technique that i described above to that location.
