Squijee Posted July 22, 2010 Report Posted July 22, 2010 hey after riding around playing some beats, when i turn my car off i hear pretty loud thud from my subs? is it bottoming out? any help would be appreciated
Blackedout Posted July 23, 2010 Report Posted July 23, 2010 It's an off/ on pop. Do you have a good ground going to your sub amp? Bad grounds can cause pops, as well as the amp turning on before the headunit. Trunk Build Log
Squijee Posted July 23, 2010 Author Report Posted July 23, 2010 the ground is fine but ill check it again. it only has done it a few time once in awhile. i just have no idea what it could be
Neo_frog Posted July 23, 2010 Report Posted July 23, 2010 Honestly, it could be a few things. Depending on the size of the amp, internal capacitors will discharge after remote wire loses voltage sending an audible bump to the subs. Also, if the remote wire is on an ignition relay, the HU will turn off before the amp causing the HU cap discharge to be audible. It could also be a discharge coming from your RCAs due to a bad internal ground. Unplug them and run the same test. If it doesn't happen, it may be the HU. Try grounding them out since there may be inaudible pops when doing things like ejecting a CD. You can test that by running digital silence and running the tests as well. And in some cases, it could be amp grounds as well. This bump is more of an annoyance than a problem. It's not unsafe for the subs unless it's progressively getting worse. Need an install?

bassl0va Posted July 23, 2010 Report Posted July 23, 2010 What amp is it? It could be a issue with the thump eliminator-majiggy circuit. My RE MT 18" wall build Former build, farewell beloved wall.In progress, Toyota Starlet build This forum has a massive boner for ridiculous electrical upgrades.
