[QUOTE="Ed Lester, post: 4646732, member: 587479"] at just over 160dB on the dash and 175 in the box, I was measuring over 800 lbs of pressure on my back wall. I used some of the strongest glues available and they will never hold without screws. Glue, screws, and some fiberglass still pulled apart once in a while. So I developed techniquies in construction to hold it stronger. In my experience. Screws hold the box together and the glue merely seals and reinforces. [/QUOTE]
