Woofer Mounting

Question.
The 2 SPL vehicles I have worked on have had points taken off because of "Improper woofer mounting."
Well that was a few years ago. Now i just like making everyday cars loud and clear. I have and always will mount my woofers with self tapping pan head drywall screws. has always worked. its not like the woofer is going to fly out of the enclosure. most of the installs i have seen use the same type of mounting hardware. after reading the official dB Drag rules and many other car audio organization rules i have come to find out that most say drywall type screws are not to be used to mount a woofer. even OEM speakers are mounted with pan head self tapping screws. what in the hell do the expect us to use? molly bolts? im jsut wondering what some of other people have used to mount their woofer.

ps
after we found out that it was hurting us we flush mounted and then put a board over the screws so they couldnt see. it worked untill we go up into regional competition and then we where temporarily disqualified for interfering with mounting inspection or some BS like that.

PSS
well tonight is my last night home for 8 days. cruise to the carribian, i leave afte school tomarrow. what is Jamacian for bye? well anyways im out.

I use 6 prong t-nuts and 1/4" bolts

I've used drywalls many a time with no issues... They bite into the wood easily and usually don't require pre-drilling. Less chance of death to the sub by impalement. If I feel picky, I'll usually pre-drill and use regular 1" pan head wood screws. I've never used t-nuts, but I may in my next B15 ported box.

a box with 2 subs usually weighs like 50 lbs or whatever. Car stereo comps are about safety .... what if you are in an accident. The box would be hurled into the passenger compartment. For a custom fiberglassed box, you typically drill a couple of holes thru the bottom of the enclosure AND the bottom of the car - then put a bolt thru them, then install the subs. For a regular rectangular box, you usually have to use some type of "strap"
