I turned my amp on today and all the bass seems to have gone from the sound reproduction. Altering the bass knob makes no discernable difference although treble does work. The only audi inputs I have are TV and CD, both of which are impacted. I have tried listening through the headphone socket and this is fine.
Any help appreciated!

It is actually in the controller, if you turn the remote all the way down and press on the controller until the bass goes off, you will be able to turn the bass up and down with the remote, mine worked but stopped after a month, I tried adjusting the amp but then I noticed that if I wiggled the knob on the remote that it would work, I mashed mine until it worked again and velcroed it to my console sonibcan get it on and off easily.
It is NOT clear what you are trying to do... HOWEVER if you are attempting to extend a bass potentiometer remotely, you CANNOT use the four wire flat telephone line as it is unshielded and you will pick up hum.
the bass nob must have worn out, that's why it cannot stay firm when you press it in.
Get something tiny like a pin, press the bass knob in, and at the same time fix in the tiny object by the side of the knob, to hold the bass knob firm, so that it will not pop out when you let go off it.
Firstly, you will want to set all options to a low pass, so the high frequencies are filtered away from the subs, avoiding damaging the voice coil. Start with the Gain of the amp about 3/4 of the way up, and all other knobs, such as the bass knob to the lowest setting. From there, test your subs for soujnd, and then change the gain and amount of bass for the sound you desire, since each person is different. I have my gain about 1/2 way up and the bass about 1/4 of the way up. If you have a crossover knob, set it to the highest frequency available, since the low pass will filter all the high frequencies out anyway.
the amp probably has a x-over knob, a bass boost knob, and an eq knob.
the eq is probably an internal crossover switch that will take the
output from either high range (tweeters) or full range (6x9s) or low
pass (subs) leave it on low pass. the bass boost however, will add
distortion if turned up too high. its not noticable in the car,
actually it sounds louder in the car but if you open the trunk and
listen, you can tell its distorted bass and actually frying your
speakers. the x-over knob is used to tune the frequency at which the
amp stops pushing out bass tones. if you like rock music loud, turn it
up higher, if you like low deep rap bass, turn it lower. keeping it too
high might give you bad sound from either type though. ALSO THE GAIN OR LEVEL.IT IS NOT TO MAKE YOUR SUBS LOUDER IT WILL BLOW THEM .the gain is used to set your amp to your head unit which there is a procedure to do it.
I just fixed my bass amp with a similar problem last week: the problem is related to a loose connection on the PCB board (likely).
A bass amp is a rough place for circuitry: the low rumble and power shake a bass amp more than a guitar amp.
In my case, the power transistors needed to be re-soldered and then the grounding bolts and screws needed to be removed and cleaned because the connection was bad. Remember that when two different metals needed for an electric connection are toughing, there is the likelyhood that corrosion WILL happen.
My bass amp did basically the same thing yours did: sounded good at low volumes, but at higher volumes it would act up.
In short, there is nothing you can do (unless you are a repair person): you need to take it to a local music shop and have a tech fix the intermittant contact problem: someone who knows what they are doing should only take an hour at most.
Hi, it is possible that the sub volume control is worn out. If your particular brand/model uses the rotary/wiper type (variable resistor) then replacing it should do the trick but this involves soldering which be done by an electronics technician or qualified to perform such repairs/replacement. Hope this helps. Cheers.
