I put more screws in, and caulked around the mount after this pic was taken.


I cut out a mount for the FR-125's from masonite, and mounted them. BHecause of the size of the magnets, theres no way to get them closer to the grill.

The problem with the stock mount is that it just holds the speaker free air. You want to keep the front wave away from the back wave. Also, the cone has nothing to push against, and so can bottom out easily. With a sealed or vented enclosure you get some gain higher effeciency.

I'm actually getting a fair amount of bass from these 4½'s now. These are a full range single driver, run without a passive crossover. I do have them highpassed at 80Hz at the headunit.

Looks like quite the project, but worth it I'm sure!

I kind of cheated with my rear fill. I too created a 'sealed' enclosure for my 5.25's I put back there, but did it using two layers (thick) of dynamat and filled it with some poly.

Looks like yours would be more 'proper' though...
