Re: volume control

If this doesn't work try a can of compressed air to blow into the buttons to clean out the dust build up.

check your may be that you have a volume limiter control on your unit. Some audion devices have these to protect the owner's eardrums.
Do a web search for the owner's manual

I have had trouble with the volume adjustment for my alpine (TDA 7552), its old i know, so i dug out the remote control to use and it doesn't appear to be working even after a new battery. could it be a...

The remote that came with this unit does not last long and breaks down very fast. Alpine has a new equivalent replacement that you can order from a dealer that will work with this unit. For the volume control, yes they do wear out with time. Cleaning it with very high quality contact cleaner like DeOxit helps for a while but the problem comes back because the mechanical contacts simply wear out. A new volume control can still be ordered if you look hard. I think pac parts can get them. You would need a technician to open up the detachable face and unsoldered the old control and solder in the new one if you can't do it yourself. After that it works like new.

I need to find out what buttons control the bass and treble

Press in on the volume control repeatedly to step through the menu of audio functions. The
first option is Volume, followed by subwoofer (only if the subwoofer feature is currently
activated), Bass, Treble, Balance, Fader and back to Volume. When adjusting audio functions,
the unit will automatically exit audio control mode after five seconds of inactivity

Amps and sub-woofer not working

Enter into the Audio Setup mode(press and hold volume button for at least 1 second). Next, repeatedly push the volume button until the display shows "2 ZONE". Make sure this feature is turned off. Hold the volume button again for at least 1 second to leave Audio Setup mode.

Now you need to make sure the Subwoofer Output is turned on. Do this by holding down(AM position) on the control knob(toggle stick) for at least 1 second. Each time the button is pressed, the Subwoofer Output is turned ON/OFF. the display should show "SW ON".

Next, you can go into Audio Control mode(press but do not hold volume button). Keep pressing on the volume knob until "Sub-WLevel" is displayed. Here you can adjust the amount of gain for the Subwoofer ranging from -15 to +15.

I hope this fixes your problem with it.

Auxilary RCA inputs have no volume control

Your problem stems from the fact that the CDA-7892 is not equipped with an RCA aux-input jack. If you're plugged into RCA connectors at the back of the head unit, they're outputs, not inputs. The sound you hear is just feeding back through the outputs and into the head unit's amplifier. If you want to play your iPod through this head unit, you need to purchase either the auxiliary input adapter (KCA-121B) or iPod adapter (KCA-420i).
