ehall8702 Posted August 22, 2019 Report Share Posted August 22, 2019 First one of my dustcaps on my 4 hds2.108s dented inward and I figured it got hit, but now a second is dented in and I KNOW it hasn't been hit cause I'm beyond careful about clearences and random things in my truck that could hit em. Subs aren't bottoming out, gains are set with oscilloscope at 40hz. I beat the crap outta my subs and run em hard but never seen a cap get pushed in from playing them. What can be causing this and how do I stop it from happening? 2009 Silverado 1500, 7.5" lift, 37x12.50r17s, Built Gen 4 5.3L ( 4.8l flat pistons, decked 243s, SS2 Cam, Pac 1218 springs, ported intake, 120mm TB, Long tubes, 3" duals HP tuner software tuned by me), 4l80e swapped and 4.56 gears. All done by me. stereo is Pioneer avh 600ex, all stinger rca, jp23 v1.5, skar rp150.4, and hertz hpd4. 2 SHCA 6.5 8ohm, 1 SHCA 3.5", and 1 DS18 tw120pro in each door. The 3.5 mid and 3.5" tweeters are powered by the skar rp150.4, the 6.5s are powered by the hertz bridged @4 ohms. Dual runs of 3/0 welding cable, 300a alternator, 2 Vmax AGMs up front. current sub is a AB XR 12 ( dual 2 ohm) with bottom spider cut out in 2.25 cubes at 32hz Link to comment Share on other sites More sharing options...

They are vented and if I remember right, the backs of the subs are like 3 or so inches from port wall. Tuned at 32hz, subsonic at 28 with 48db cutoff . I do play alot of decaf and deep stuff too. Hell even the surrounds get warm after long play time from the excursion lol 2009 Silverado 1500, 7.5" lift, 37x12.50r17s, Built Gen 4 5.3L ( 4.8l flat pistons, decked 243s, SS2 Cam, Pac 1218 springs, ported intake, 120mm TB, Long tubes, 3" duals HP tuner software tuned by me), 4l80e swapped and 4.56 gears.

WalledSonic Posted August 22, 2019 Report Share Posted August 22, 2019 I know youre trying to figure out why they dented, but perhaps you can try popping them out with a vacuum attachment. I use the powerful one at the local car wash.

Noticed only the two subs with port wall behind them are having this issue with dented caps. Not much I can do untill I redesign a new box I guess. Wtf is happening that would make the dustcp dent in?
