Hi. My sub is driving me nuts. It (apparently randomly) goes to full volume, then will stay on for a random amount of time. It happens regardless of what is being played, what RCA leads are being used, or what input (left, right, or both). Moving the lead (at either the sub or amp end) *sometimes* makes the bass stop.
It's now doing it 30% of the time and is un-useable as a result. Someone in a hifi shop recommended taking unscrewing the back & blowing the connections with an aerosol blower which I did best I can, but the inside of the RCA's are mainly covered with plastic so I'm not sure that it would've done any good anyway.
Any help is much appreciated!
Re: sub kicking out full volume bass for no reason
It's you power from the battery/alternator, it's not supplying enough power to kick it on, if you turn the volume down you'll notice that it'll stay on. You may need to re adjust the settings on your amp or get a bigger alternator, maybe even install a second battery.

I suppose the problem of your unit is memory, sometimes this problem can be fix by applying service mode, but if not, then memory should be replace and I would advise you to send your unit to service center.
The amp might be on protection mode when both subs are driven...sign of an overloading problem. Does it work fine at lower volume levels? Check also the amp's supply voltage if it fluctuates out of tolerance level...might also be a loose connection in the wiring or terminals in the supply rails.
Your probably overheating your amp from running at too low impedance. Check what your amp minimum impedance is, and make sure you have your subs wired at or above that. Remember, if your running a multi channel amp bridged the minimum impedance goes up. Check the manual and see what the bridged impedance is if your have your amp bridged. If this isn't the problem, check your sub wires and make sure they're good and secure, and not connecting, and disconnecting... Hope this solves your problem
probably your power is too short, increase your gauge wire, and your ground wire of the amplifier has to be shortly as possible, and the positive has to be enough to support peak power, you can also put a big capacitor on the positive wire to give some more power while the bass peak.
hard to tell whats causing this .Just curious make sure speaker wires going to subs are POLARIZED meaning positive from amp is with positive at woofer and NEGATIVE is with negative at woofer.When these are crossed and when volume is raised you will hear the bass cancell each other out..
Turn the bass gain all the way down., Turn up your your volume on bass test song. Crank up the little box next to the steering wheel wide open . Now go gradually turn up the bass gain on the RF amp until you get distortion. Turn the gain down slightly. Now you can enjoy playing the bass from one end of the little boxes setting to the other without ovrloading your amp and subs. Open a can of whoopass on anyone who tries to crank up on your gain.
