On my amp the protection light apperas when i hook the rcas up (red and white cables), i changed the leads looked at all the other leads eg power earth etc. do you have any ideas, many thanx wayne


turn down the amps gain and radio volume to lowest.

a. disconnect the RCAs at the source end. (at the head unit)
b. connect only 1 RCA at a time to the amp. ok?/fails?
still fails? u have a short in the RCA wire. toss it.

didnt fail?
a. with radio off, connect RCA to radio while RCAs are connected to amp.
fails? you've got a dead short on radio side.

does not fail? turn on radio...fails? radio is issue. (not very likely though)


my quess is that you've left out a significant observation as the probability of a shorted radio is low and you say you swapped RCAs.

I have a pair of kicker cvr 124 with a kole 1500 watt amp that is bridged to the woofers. the amp is 385 rms at 2 ohms where should the gain be to get the most power without distortion.


When setting your gain you want to set the gain high usually between 75% to 95%. if the gain is low than turning up the volume on your radio will only amplify the distortion coming from the under powered head unit. By turning up the gain you are maximizing the signal that is amplified coming from your head unit

I have a Panasonic Unit, two reference components hook to the front outs, and a 500 rms monoblock with a 12 inch woofer. The problem is that when I turn up the volume the radio stops the music and after a...


This is most likely caused by an overload from the amp. Depending on what setting you have it on, you should adjust the gain and any other boosters to about midrange. If you put it all the way it will cut out as you're experienceing. Try to lower the gain and such and see if that helps. If that's not the case, then your amp may be damaged and can't handle the load.

Someone gave me amp, dont know how to adjust it


What kind of amp is it? This will help with proper setup. 1st turn down the gain on the amp. 2nd if the amp has a crossover determine if you want high pass or low pass. There may be a switch and a knob with markings like Hz 40-100 ect.. with the gain down turn the volume up on your radio 3/4 of the way up. Now slowly turn up the gain till you hear distortion and back it down a little. Sit back and enjoy :D

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.

My Radio and clock screen has went blank volume and controls do not work the clock does not work the radio plays and CD plays but screen is dead. 2001 525I BMW


it sounds like the Multi information display has failed (MID). It is the long display with all the radio controls on it. If you want to find a known good part they are really easy to swap out. Just remove the radio knob and if you look down in there, there is a place to put a T10 (i think maybe bigger or smaller) torx T10 screwdriver.if you turn it while pulling back slightly on the screwdriver it should come right out. It usually is the component that fails but as always you may want to check your fuses.

Sub woofer volume adjustment


The gain dial is not a volume control. The gain dial is used to compensate the output level of your car radio head unit. all car stereo units output are not alike. If you set this gain level too high, it will cause major distortion (clipping) to the audio output of you speakers when cranked up. This excessive distortion WILL eventually, or even quickly damage or blow your speakers.

I personally blown speakers this way no not properly setting this. (lesson learned, I guess :| )

Peavey Bass Amp TKO115s


Start with a clean setting - zero cut and zero gain on the Eq. Play a song close to the amp, and then move away, playing the same notes. Do you still get the distortion? Change lower the input gain and repeat the test. Lower the output gain and repeat. Are any outboard distortion pedals in the mix, such as overdrive? Eliminate them. Run straight through from your axe to the amp. Check for any distortion settings. Set everything including reverb to zero. When the distortion disappears, this is your base setting.
Change only ONE parameter at a time. When the distortion comes back, you have found your problem.+
