Thats funny. FAIL

This is turning out to be a pretty good thread, very informative. Maybe it wasnt such a dumb question.

One of the main reasons for the screws was, when trying to build a couple of boxes a day. you dont have time to let glues dry or silicon fumes air out before getting the carpet or vinyl on it and mounting the sub so it can get into the customer vehicle. But now that the only boxes I build are for my own vehicles, I can take my time

yea, I wish they had these forums when I had my business. Alot of what I did was trial and error. It would have helped to have all of this knowledge at my fingertips.

This guy make a really good point.

I can say that I never had a box fail on me in 10 years. I usually overbuilt them.

I always used the wood glue and liquid nails to form a tight seal more than rely on it for strength. I actually started out using clear silicon till I found out the fumes can errode the surround on the subs.

I owned a car audio shop for about 10 years, but I closed down about 6 years ago. All of the sub boxes that I built I used wood screws and liquid nails or wood glue. I have seen a few boxes on here that seem to be held together with just wood glue and no screws. Will a sub box hold up to the pressure if you dont use wood screws to anchor it down? Or is everyone using wood screws and I just cant tell from the pics.

Good Job! Who took first place in the two classes.

havent seen it yet.

Or, turn the center console into a sub box. (if you have a center console)

Cool

the JL 10w1's should work also.

I have a super crew, same year and I put a pair of tens under the rear seat. I would recommend the sundown sd1's cause the mounting depth is only about 4.5 inches. http://www.soundsolutionsaudio.com/forum/i...showtopic=17667 Works great for Rock music, but doesnt really have the hang time for some Rap songs.

does the amp have a phase switch on it?

try hooking both amps up and switching the positve and negative speaker lead on one of them.

Thats true, didnt think about that. Give them a chance to loosen up, if they are brand new.

try turning off each amp and running just one to see if there is any difference in output.

did you double check that none of the coils were out of phase. Still think you need more power than that.

I think you will need more power than those cerwin vegas. Just my two cents

video of the hairtrick or it didnt happen. Nice system
