Go into your settings in the deck by holding down the volume on most models for 10 seconds then change your hpf settings and your lpf settings your bass will sound much better and not cut out. hpf recommended 160......lpf recommended 140.... good luck

How to adjust Dg11100 car amp


If your head unit has an amp gain, turn it up as high as it will go. If it is hooked up to subs, the head unit will say subwoofer output in the menu. Then take a small screwdriver and turn the amp gain on the side of your amp counterclockwise to zero. Turn your freq. up to about a third. Crank your system up, with a song with good bass, and slowly turn your gain up till the bass from the subs sound distorted, and back it back down. If the bass is drowning out the other speakers in your car, then turn the gain down some more. I find it works best if you have your trebble up high, your mid range at a little less than half. And your bass at zero or one. Your amp is cranking up the bass, so let your other speakers handle the rest. This allows it to sound clearly at higher volumes.

I have an Alpine M500 mono amp that works great, until you turn up the volume. I can adjust the bass down at the head unit, but at higher bass the amp shuts off. And then comes back on after a couple...


I don't think either, I believe your running theamp load too low with too low an ohm speakers and this cases the amp to produce more power but not stable and it overheats and the thermal protection cuts the amp off when the temp gets too hot to prevent damage.. Make sure your speakers depending on how they are wired do not exceed the amps load rating

My left speaker to my Sony HCD-GX450 stereo is


Make sure that Loudness switch is turned off & bass is not boasted up. Most cars have small cheap speakers that can't handle the bass. also its better to cut the low frequency from the woofer using a passive or active crossover. Most nowadays head units have got some sort of built in crossover. Refer to your head unit manual.

Cut out


Do you have ONE pair of 12's? Are they single voice coils? Dual? Bottom line, you are either over driving the amp (bass controll up high on the head unit (stereo), or the "load" on the amo is too low, meaning 2-12'" dual voice coils parreleled would give you a 1ohm load. Need more info, need to know what the bass is set on on your stereo, what size power wire to the amp, and I can wrap up the solution. ok?

Take care,

Why does my KAC-8404 cut off at high volume bass?


amp 101

1/0 wire to the amp or the amps will loose power

check the connections mainly the negative

wiggle the wires see if you get a cut out or not

a cap will help you give constant power to the amp and not allow them to drain on long bass notes

hope this helps

Amp clickin in and out


Had a similar problem, mine was a power problem.
Power meaning voltage.
Those big bass speakers draw lots of power. My original alternator couldn't keep up.

Question: Do your headlights dim in rhythm to the bass hits?

If so, your sound system wants more power than your vehicle is producing.

My first solution was a high output alternator. It worked great.

Then I added another amp. Not great anymore.

My second solution was to tie in a large capacitor to the amps power supply. (These a big (1 farad), about the size of a Pringles can)

Your amps power consumption is not uniform. Each time your amp punches the bass, it draws extra power. If that power isn't available, it starves and shuts down (if only for a second) then restarts.

The higher the gain, especially using a low pass filter, the more power needed for each thump. Thats why when you turn the bass down, you can get higher volume from the rest of the system.

How a capacitor can help (simply put):
In this application, the capacitor acts like an auxiliary battery, smoothing out power fluxuations. The capacitor builds up its charge literally between bass hits when power demand is low. Then releases it's charge when the demand is high. Think of it as an on-demand power boost.

Hope this helped

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.
