I posted earlier in the Subwoofer forum about this issue, which I believe has more to do with Electrical issues or my Amplifier.
Equipment: JL 12w7, JL 1000/1, custom 1.9 cube box tuned to 27hz. Gain on the 1000/1 is @ 50% (authorized dealer shop installed this way and equipment has never been changed to necessitate a change in gain).
Problem: Subwoofer cuts in and out throughout play on bass-heavy songs at higher volumes. On other non-bass heavy songs (with bass nonetheless) I get normal playback.
Knowns: My amp does not go into "protect" nor do I get any other notifications "low voltage", or "low ohms" on the amp. Everything's been playing fine for well over 2 months. I keep my h/u's subwoofer gain usually at 6/15 so I have headroom when I rarely crank it up. I have a common ground & power going to distribution blocks where I have the 1000/1 & a 4-channel for my components. The 4-channel plays just fine which to me rules out the main ground, power, & remote turn-on. The speaker wire is not exposed or grounding anywhere. My RCA's are all very secure, as well as other connections at the amplifier. The subwoofer's terminal post has secure connections on the outside, although the inside is soldered with tin and wrapped in electrical tape (in other words, it's POSSIBLE but not likely I could have a problem here). The wire to the subwoofer is connected securely as well. Basically everything that I know to check has been looked over numerous times.
The crazy thing is that I can literally tap on the amp when the subwoofer stops playing and it picks back up again. I can also leave the trunk open and playback is fine. However, shortly after I close the trunk the subwoofer will cut out. This is leading me to believe that there is something loose inside the amplifier itself. Almost like the pressure in the trunk is causing something in the amp to come loose.
I'm to the point where I'm about to call JL tomorrow (if they're open) and talk with someone in the tech department to see if I can do some troubleshooting with them. I had this installed by an authorized dealer about a year and 5 months ago and have original receipts. Doing so allowed me to get a 2 year warranty rather than a 90 day warranty, so if worse comes to worse I should be able to get this repaired or replaced on warranty.
Can anyone give me some direction here?
