Guys..WHy not use a pop Rivet on the lower inside area of it...It will never come off that way...EVER...Unless you want it to.
Is there access to the are behind the grill to do this?
And FG is really strong if its made right.
I do a lot of FG work and I have had plenty of FG body kits in the past that hold up plenty fine to 100+MPH speeds.
And the guy about the Sub box's...Right..you must be getting some bad work done....A well made FG box that is the right Thickness will take a beating with no problem.
The problem when buiolding box's is that no one wants to build the FG to the 1/2'' thickness that a heavy hitting sub needs.....If you only use four layers of glass....Hell yeah it'll crack.
Just my .02 cents here guys...But I would look at a some type of mechancal fastening for this item Vs. duble sided tape.

I forgot to say I like that pop rivet idea.... maybe tomorrow I'll get to looking at my car and seeing if that can be done.... thanks (thumb)[/edit]
Question....... How long have you been in the car audio field? Building fiberglass boxes for subwoofers?....1/2" thickness wouldn't cut it either, no one wants to build heavy fiberglass boxes because of cost and weight. your car isn't gonna look too cool barely riding on it's springs/shocks, it's cheaper and less weight to build the box with balsa wood, and it'll stand up to the beating for a long long time..... Just ask some professional builders, and professional sound competitors for their opinions and experience? I wouldn't think they use only 4 layers of FG on their setups involving 5 or more woofers.
Just like a car with chassis flex, it doesn't hold up to that, even though it's made of steel, over time the body of the car gets warped going through the hard corners. (a good example would be an auto-x car)
I mean, no one really wants to put crappy (flea market?) subwoofers into their car, right? Everyone wants quality. Two 12" subwoofers that handle a peak of 1300 watts, and you have 2 1000 watt amps, and your setup has your subs are basically getting juiced to 1000 watts each and pumping that bass out.... you're saying the FG is gonna last for as long as you have the system? Ok................. maybe if you made it an inch or 2 thick (minimum) and dealt with the weight. Yeah it would hold up. I'll just built it with the would for only 1/4" to 1/2" thick and have it hold up just fine.
As you said fiberglass "done right".... like the fiberglass body kits, Buy a crappy one and tell me if you think it's good quality. This guy is obviously half assing s*** and charging $150 for it.... I think it's because he knows many people don't want to pay, or can't justify paying, or can't afford $400 for the autoexe, and he's pretty much the only other option, isn't he? And he's saying people aren't doing so and so for his piece and that's why it's breaking.... even though they ARE following the instructions. It's cause he's making them bad.
Since you work with fiberglass, help us out, take one for the team
..... make a grill, make it right, the right thickness, whatever you think needs to be done. Then check it out and let us know if it holds up (compared to this guy's work) ya know drive 130 mph or whatever.... if it does hold up, please tell us how much you think it would cost (while making a profit for yourself or whatever builder) to build (cost of supply and demand) and sell the grill of YOUR design...... if you can make them and they're sturdy, and worth it, I would buy one from you. Good luck (thumb) just remember the thicker you get, the bigger the piece is gonna look, you might get it to the point where it doesn't look right
