Excellent work on the roof, window channels, and the frame of course.

That is going to be a awesome car when finished. Hell, it looks pretty damn nice as is.


But a little something to offer from my car audio experience, since you went through the trouble fitting 6X9s in the rear deck. I try to limit the amount of rear fill that I use in a vehicle, as it tends to create a hollow sound.

For example, I have 100X2 on the 6.5 components in the front of my truck and 25X2 on the 6X8s in the rear. Even with the difference in power, I still had to turn the output of the rears down to eliminate the hollow sound.

Given, the rear speakers in my truck are in the rear doors, which is just behind the front seats. Every vehicle is different, but the problem is still relevant.

Just something to think about, especially if you can't figure out why something doesn't sound quite right.

ok thanks.  the package tray came with the flange/cutout for one 6x9.  i basically cut it, moved it over and added the same piece of metal from the donor roof for the other side.

i'm not understanding what you mean by rear fill though.

Ideally, your car audio should sound like you are front and center at a concert. The sound should come from foreword of you, from as equal of distance as possible (this is why kick panel mounting is preferred over door mounting). Any sound coming from behind you (rear fill) should be just enough to provide a fuller sound to the cabin, without disrupting the foreword soundstage.

However, it should be noted that bass is pretty much non-directional.

This explains it pretty good.

i understand now (i'm not an audio person).  by "rear fill" you simply mean, i may need to turn down the volume in the back compared to the front...

If all you have is a fader, I guess it would be that simple.

On mine, I was able to put a little more mid-bass into the rear doors to help create a fuller sound. And since bass is non-directional, you don't notice that its behind you. But the ability to do that requires more equipment, and an understanding of how to tune it.

If I need to add a crossover cap or ind, I can do that if needed
.  Already plan to start with a 200u in front to help with the pocket.

That should be a good start on the front. That would be around 200hz at 6db.

Depending on what head unit you buy, many of the newer ones have built in electronic crossovers. This is how my sons truck is setup.

If you are only using head unit power, I might would add a 1000uf cap to the 6X9s. That is ~40hz at 6db, which shouldn't do much more than filter out some subsonics.
