i was lookng at some threads about subs in the back doors. and it looks like i would like to do them in fiberglass. ive never used fiberglass before and was looking for some help on the best way to do things. pics would be awesome. or if there is anyone you know around Riverside CA who does fiberglass that would be awesome too.

thanks

 

I am not sure who did it this way but one of the members did it by making a strong subframe to mount the speaker, then he stretched something like pantyhose over the frame to the door frame and coated it with resin.
Then he added fiberglass mating (what type not sure) until he got the thickness he wanted.
Cut the hole and joint the sub.

I am not a stereo type of person and I have installed speakers and amps but as a kit not something I. Have put together, that said... Will the location you have chosen for the subs have enough volume of air so the sub can do best what it does, put out BASS ?
Just asking, I am always learning.

 

if you look in how to for audio look for the one that says puting 8's in the doors. thats what gave me the idea. and i think if you do the box right it will sound good enough
