OK, where is this project going? Well, it's going forward. I already bought the fiberglass needed to make the enclosure. Mold? Paul Shpakov wood speakers. He was right, it's too heavy for the door. Swing it enough, and you might mess up the hinges. THAT is a very undesirable situation, a door that cannot close properly. The solution, make them in fiberglass using Paul's wooden frame as a mold.
This is the idea, place a set of Rockford Fosgate P1692, 6 X 9 front speakers in the area intended for the 6.5 speakers. (Frequency Response 60-22,000 Hz). The infinity speaker that were in that hole are going to be hooked up as mid-range in the crossover outlet.
But the speaker mount must be strong because these speakers are heavy. How, like
this.
Then, the screws will have a piece of metal crossing the inner fiberglass to reinforce the screw with metal flat washers to be torque. The enclosure with new Fiberglass, but the skeleton will be aluminum. For the fiberglass enclosure, I will install
Car Sound Deadening Mat Sound Deadener Insulation Material. This will help sound and give the piece rigidity. Stay tuned, mensa...out.
