You don't give us much to go on...

Are your subs self-powered? Disconnect the Line In to see if that makes the pulsing stop. if it does there's some kind of signal coming from UPstream or a cable has poor shielding. If it keeps pulsing something's wrong in the sub's power amp(s).

Isolate that much and come back.

Light blinking and sub just sounds like a heart beat


Swap the wires of your Sub with another channel and if the same sounds comes out, you blew your sub. If a different sound, you blew a channel on your Amp

Hi we tried this system is new with denon stereo reviver. And with ioneer AV SYSTEM. Both with ower to sare but the cubes beat the sub by far, Cant get the sub to sound harder or sound like in store....


Some careful typing and model numbers might illuminate the question a bit.

Have you adjusted the speaker levels according to the manual?

Also, bass is heavily dependent on nearby surfaces. Experiment with placement of the sub. Find a spot near a corner.

2 12" subs + 600W amp. Turn on, goes boom once, then red light


Is your gain all the way up? If it done this before, sounds like your over working the amp. Make sure your subs ohm load is capable with the amp load to. If they are 1 ohm and your amp is only 2 ohm stable, it would beat for a lil bit then go into protection mode to. Check your wires too.

Sound from reciever


LFE (ONE CABLE ON THE SUB TO SUB OUT ON AVR) OR stereo L/R analog cable from sub to tape in/or out on avr (depends on AVR) LFE connection the sub turns up with the AVR - the stereo cable threw tape in/out on AVR only turns up via its own onboard amp volume from AVR has no affect.

Subwoofer noise


You didn't say is your sub active or passive.If its active first check signal cables from theater system,power line of the sub, it has to be the same phase as the system.If its passive take a voltmeter disconnect the sub from the system and measure for DC voltage on the SUB output on the system when its OFF.If DC voltage is present your amp is damaged.It can also be that the preamp circuit for the sub doesn't mute the input when unit is on stand by and you hear frequency of your power supply (50-60Hz) on the sub

My JL subs just dont beat like the ONES IVE HAD before as well as the ones my friends have had


sounds like they have your sub amp in mono but they put the speakers in series which totally cancels the benefit of running your amp in mono. you will probably be happier if you just hook the left speaker to left plus and minus and the right to right plus and minus. Cuz even though subs aren't directional they do pass some higher frequencies that are and that dilutes the stereo effect.

Car amp's stopped working. Putting out a heart beat sound through subs but no bass.


could be low current ,disconnect all power including ground for 20min N.B most amps will seem to be shorted at output but this is normal due to damping ratio.
