My amp turns on good but after a while of too much bass causes a ugly sound too loud what could it be? Can it be repaired?

If you have over driven the amp by playing it real loud with the bass control turned up, it is very possible that you have toasted the output stages of amp.
Every time you boost a tone control by 3 db you have doubled the output power at that frequency. So if you are "coasting" along at a nominal 75 watts, the moment you boost the bass by 3 db the amp has to put out 150 watts at that low frequency.. Go to +6db and now the poor amp has to kick out 300 watts! And so on.

Rule of thumb - you never use your tone controls at very loud levels. Tone controls are there to compensate for the poor frequency response of the human ear at low volume levels - the Fletcher Munsen effect. At low volumes our hearing with the lows and high frequencies so when you play something at low volume you boost up the bass and treble to compensate for poor hearing. At loud volumes our ears respond properly.

My Audiobahn A2301q amp is pumping continuous bass as soon as I turn the car on

When you say it is "pumping continuous bass," is the "bass" you refer to part of the program material from your audio source, is it a continuous low tone, or is it a random popping or thumping with no correlation to whatever program material is being played by your audio source?
If it is bass from the program material you are playing, please further explain why this is a problem.
If it is a continuous tone, you have an open feed line or a defective amplifier.
If it is a random popping or thumping, it can be either a bad feed line, a bad amplifier, or a partially-burnt speaker voice coil.

I have a kicker 750.1 amplifier. I was playing it one day pretty loud and it cut out once the bass hit and started smoking.The gain was up about 1/4 and the bass boost was about half way. what could of...

I would say that your subwoofer Or speaker leads have shorted out...when the bass hits as you say it drives the amp hard but if it is trying to dump power onto a shorted speaker or speaker wires it will blow the output power transistors not to mention other vital components of the power amp...i suggest you test your speaker leads with a Multimeter on the ohm setting before connecting a repaires or another amp.. to make sure there is no short on the leads and that the resistance is around 4 ohms or so depending on how you have your drivers wired...but anything lower than 2 ohms will cook an amp! you can normally pick up a meter from anywhere for around $10..

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 trouble

The ohm load may be too low. What make/model amp is it?

your amp may be overheating, or you have it up too loud and the surge protector is shutting it of in fear of damage to your amp.

Amp went into protect, but front speakers sound distorted too

If the amp still goes into protect mode, the easiest thing to do is disconnect the RCA cables from the amp and see if still goes into protect mode (after turning off/on). If it does, the issue lies in the amp or the wiring to/from the amp (most likely case). Check to make sure no speaker wires came loose and touched +12V or ground (car body). From the sound of it, my guess is something internal to the amp died and will need repair.

Crate BT50 Bass amp cutting out with high input.

Sometimes an amplifier's preamp can't handle certain signals/frequencies at a high gain, so they cut out. Bass guitars are especially prone to giving such a strong signal.
I bought an older, nonworking bass amp recently and fixed it just to find it had the same problem. Best solution is to put a low ohm resistor at the amps input, but if you turn your guitar down to half volume it'll have the same effect: should prevent it from cutting out.

Amp cuts off

You may have a problem with the power source feeding the amp. You need to check the voltage across the amplifier's B+ and ground terminals when the amp is playing/cutting off. If it's dropping below ~11 volts, you need to determine why it's dropping so low.

The Amp stays on because you have a constant 12V to the Remote.
If your stereo remote is no longer working then run a wire from a 12 volt source that turns on and off with your ignition something like your radio fuse in the vehicle fuse box.
As far as the Bass Knob if it is connected properly and still not working check the line for wire kinks or cuts that may have happened during installation if you cant find any problems you can get a universal bass knob that plugs via your RCA cables for under 20 bucks.
Hope this gives u some ideas.
