Yes



Friend of a friend built them for me, they're custom so you could do whatever style you want.

These are built to hold 3 10"s, 2 tweeters, and a horn per door.
Probably the cleanest custom panels I've seen made for audio. Most of the time custom door panels with speakers look odd and too busy.

I noticed more water dripping from the left rear again. So I started pulling the lower door weatherstripping and this happened.

I finished pulling the rubber off, and pulled the "drain plug" out of the door. There was a LOT of water in there.

I'm guessing this is from a bad window seal. I dont see any other way for water to get in there. Any other ideas?

Not necessarily bad seal they are not exactly watertight, so it is acceptable for some water to get in the door, just make sure the drain holes are not clogged.

Oh, and I noticed the rubber seal strip started separating from my new, aftermarket CHMSL after only a few weeks.

After spending what felt like an eternity trying to reattach it, I just pulled it off. I figure it's not really a seal, but probably just to reduce wind noise. I looked at the OEM one, and it seems to be glued on. On this one, it friction fits into a groove. I'll try gluing it. But I think the only way I'll get it reattached is to pull the whole thing off the truck and reattach it on the workbench. Is there a trick I'm missing?

What drain holes? Every hole in the door had a rubber plug in it.

The other three doors were dry, btw.
There is a small drain hole in the corner. It's right above where the seam from the door skin is folded over.

Btw, I removed the rear most plug from each door and kept them out.
