Speaker system
 

I got my car pretty gutted right now, and I'm trying to plan out how I wanna do the speaker system. I've done some investigation and I think I've decided on going with focal speakers.

1 X Focal 40KX 16" sub in a sealed fiberglass cabinet
2 X Focal 690CVX 6X9" 2-way /w tweeter for back
1 X Focal 165 KRX3 kit for the front (not sure where I'm gonna put the tweeter, includes 2 X 6.5", 2 X 3", 2 X tweeters)

That's 1360 Watts max power. Will I have to do any upgrades to the electrical for this to work?

That sub is going to need a big box . You probably would get better results with the 13" . Unless you are planning on eliminating the rear seat.

Tweeter in modded a-pillars would be best

what amps are you planning on using? And i agree...the 16" sub might prove to be a little tricky to wedge in there :)

Actually, my plan was to eliminate the back part of the backseat, then upholster the box in such a manner that it becomes your back support... that vibrates a lot :)

I want a large sub to hit those real low subsonic frequencies.
