Hi there
i beleive that underneath some dustcaps is unsealed. the dustcap in some subs encloses the motor that drives it. I would suggest getting it fixed in 1 way or another just incase. Having the motor exposed( if it is) can burn out if unattended to.
I hope this helped.
thanks jeremy

We have a toilet problem now for 8 years since we bought our place,the toilet leaks onto our bathroom floor we know where the leak is someone have put silicone around the plastic valve right @ the bottom...


With out seeing it, it is hard to actually know what the problem is, but it sounds like it is either where the water line enters the tank, or the gasket between the tank and the bowl. Either way there should not be any silicone. The water line flows into the fill and shut off valve. If it is leaking from there get a whole new valve for under $20.00. For the gasket between the tank and the bowl you have to remove the tank and replace the gasket.

What many people are unaware of is a small crack in the tank and rarely a small crack in the bowl. If the leak is not from one of the two things I mentioned above it has to be a crack and in that case a new toilet.

If you can not tell where the water is coming from it could be a crack or the wax ring under the toilet may need replaced. You might want to call a plumber and get a free estimate on what the problem is.

Good luck with this.

The foam in critical to locate the magnetic cone correctly, silicone will not do that. The repair is quite reasonable and my speaks worked correctly when I got them back.

Sounds like your sub is overextending itself, and possibly losing contact at the voice coil. Overextending will make a weird rattling sound, losing contact at the voice coil will make a popping sound.

The subs aren't pushing out bass.


Hello crobins2,

The Kenwood KAC-6202 2-channel is only rated for 60 watts RMS per channel into a 4 ohm load. That just isn't much power for a pair of 12" subs. Even the bridged output is only 200 watts into 4 ohms, still at the low end for a sub, much less to share between a pair of subs.

Assuming that your subs are 4 ohm, you could probably get more sound by driving just one of them on the bridged terminals. But to get the best power with what you have, connect one sub to each channel, set the filter switch to the far right (LPF), set the operation switch to stereo (both channels driven), set the filter frequency (Hz) to 100 or lower, and adjust the input sensitivity as far clockwise as possible without causing distortion.

But, to do the subs justice, you really need at least 300-400 watts to share between them.

Hope this helps.

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.
