Head Unit Shuts Off At a Certain Volume

Alright.this is a problem that has been ongoing since i got this alpine unit. When the volume gets too high, the unit just shuts off, the display retracts as if i shut it off, and then it turns back on as soon as the display is fully retracted. This usually happens at around volume levels 20-23, and will rarely get anoy louder than this. Anything with prominent bass in it, e.g.; rap, will shut off at a lower volume level usually starting at 18. please, any input will help me

    I have an Alpine CDA-9847, which is powering 2 sets of Powerbass 3XL-60C speakers (4 woofers and 4 tweeters), a set of L-4002 coaxial power bass speakers... and now i have a Kicker ZX400.1 amp powering a Powerbass S-10 10" subwoofer.

    Songs with some heavy bass will cause the head unit to pretty much reboot. Shuts off then a second later comes back on. What is the cause of this? I read somewhere that there is a bad ground, that its grounded through the antenna? Should I just ground it myself? Thanks!

Check your ground, it could be that your antenna is the only source of ground, in which case the deck does not have enough power to stay on when it draws too much power. I've seen exactly what you are saying many many times. Ground it really reallly good.

You need an amp for your speakers. You are not pushing enough watts to the speakers causing the radio to shut down.

Press the Rotary encoder (CDE-9845/CDE-9843
only) or press MODE (CDE-9841 only) repeatedly
to choose the desired mode.
Each press changes the modes as follows:
BASS: -7 ~ +10
TREBLE: -7 ~ +7

Fader : R15 ~ F15

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 alpine 9965E LCD display keeps on turning to black after a few seconds, but the head unit works. If i increase the volume, go to the next track, the LCD display pops out again

you have turned on the "black-out" feature to get it back look for a little button over the volume knob with either "dispay" or "blackout" on it. Press and hold it and you will hear a beep to let you know you changed it. Why Alpine put that feature in the head units is to confuse and comfound drivers is my guess.

Volume issue with Alpine CDA-7839 and Soundstream Continuum

Interesting that you have a Soundstream "The Continuum" amplifier. This is limited edition of the Reference 705 amp produced with a polished aluminum (not chrome) case. You have a very hi quality - Old School - amp.

Properly installed this amp should produce more than ample volume levels and certainly far more than a stock unit.

Because the Alpine head unit provides sufficient voltage to drive the amp, it is likely either the wiring, or, the way you have it set up.
The amp has a large internal capacitor bank and for proper operation, this amp must be connected directly to your car battery, prefereably with 4 AWG. (The amp is made with 4 AWG power connections.) Use high quality speaker wire run directly from each speaker to the amp.

If you have done the above, then it is probably the way you have it set up. The amp is sophisticated with many configuration options. Do not change any switch settings while the amp is playing. Ensure you have the appropriate inputs and crossover selected. Check the gain settings.

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).
