Hello, here's my project.
I allready have all the pieces (exept one ampli).
I have one question :
Can i put the new ones in the original support ?? (same size)
In fact it's my car dealer that will pass the wire through the car because i don't want to lose my warranty

...
4 x 17 cm in the car (flat speakers to avoid vibrations with the plastics)
2 x 20 cm on the rear board (for medium-bass)
1 x 38 cm sub + 2 ampli's in the chest.
Thanks for reading.
Fred.
PS : sorry for my poor english (frenchie)
