15 days for a free retest. Any longer, and you get to pay again.

I am also in Utah. SLC to be precise. 81 BRAT GL. Since we seem to have a local inspection guy here, I'm going to hijack the thread and ask about a shortened exhaust. I was failed for mine that ends just behind the rear axle. But when I looked at the book online, it reads that on pickup trucks, the exhaust must end behind the rear of the passenger compartment. Do I simply need to remind the inspector of the code?

Speaker wire isn't that expensive. It's made for high temp environments and intended to withstand lots of vibration and flexing. I'll admit that I'm a bit of a geek when it comes to my car audio, but I always use at least 12 gauge wire for amplified speakers. I've gone as big as 6 gauge for woofers. It's really helpful go with larger gauge wires to supply power to your amplifiers as well. Too small of wires will damage your stereo gear and won't give you the best possible sound. I'm fairly knowledgeable about car audio, so feel free to message me any questions you might have. And here is the URL for my favorite car audio reference site http://www.the12volt.com. They have lots of charts to help you figure out wire gauges, as well as tools to help build crossover networks, guides to doing things with relays, advice on selecting speakers, and tons of other stuff.

@Ever Victorious. I have a small enclosure as you described with a vintage 8 inch Aria DVC woofer in it. But I want to go as large as possible, which means using the available space as efficiently as possible. The plan is to build the box, then find the volume and match a driver to the enclosure. The difficulty with having something custom made is that there's a lot of figuring out and mold making, so it's more expensive than most of us are interested in. @Knopper. For my doors, I'm reusing the Kenwood dual mag components I had in my 90 Legacy. The car came with these funky adapter rings that angled the mids very nicely. I cut the stock speakers outta them, then welded a 14 gauge steel plate onto the front with a hole in the middle for the driver to fit into and then the bolts that hold the driver thread into the plate. And finally, I glued a couple of the cheesey plastic speaker tubs that stereo shops carry onto the back. A little Dynamat and some Permatex undercoating and it's very solid and quiet. I put my tweeters right in front of the door latch. I had to cut through some steel to give them room. But it's probably the best tweeter location in the car. I didn't feel good about the tweets fitting into the A pillars.

So I'm working on fabbing up the sound system for my 81 Brat. With the space limitations, I'm thinking the best way to add woofers is a custom built fiberglass box to fill in the space behind the seats. The reason for this thread is I'm curious if anybody else would be interested in a copy of the enclosure. I'm going to have to build a mold and it's not a huge deal to build one that will last for a dozen layups rather than just one. But I would need to know that several people are interested before throwing extra money at it. My best guess is that copies will cost a couple hundred each, but don't hold me to a price until I've got the first one finished and know exactly what's involved. I'm not looking for or offering a commitment just yet. Just want to see if at that price there's any interest.
