    Hello tertul, I agree with pbabin, he has helped me out in the past and is currently helping me with an infinity amp and it is unusual for just on channel to stop working. I know about electronics as I have a degre for an electronics tech from the mid 1990. I'm just getting back into repairing electronice and it's mostly car amps.

    But, it is possable for one channel to blow out, meaning the output transistors to short out, that should cause it to go into protection mode though. I'm not exactly sure cause I had an amp the same way and the output transistors were shorted and did'nt cause it to go into protecion mode so like pbabin said, check all connections and speaker at that channel and you head unit. Then let us know. pbabin will be able to help you better than I can at the moment until I get some more car amp repairs under my belt then I hope to be as good as he is. Good luck

I also want to add, I just got a crossfire ct-2200 oldschool amp I bought from E-Bay and the description described it to be as one channel not working but other side plays fine. Well, when I got it took it apart did basic test everthing turned out fine. So I hooked it up turned the power on and one channel was'nt playing. I thought maybe something in the input circuit in the amp, the preamp section maybe an opamp. Anyway it turned out to be the sub frquency switch and the stereo or bridge selector switches had sirty contacts. So I sprayed some contact cleaner in them and then a little WD40 to keep them lubricated for sliding. So maybe that might help you out also. Once again, Good luck and let us know what you find out.

Have you moved all of the switches, controls and RCA jacks to make sure that the problem isn't a dirty contact?

Have you tried swapping the RCA signal cable from a working channel to confirm that it's not a signal problem?

Have you swapped a speaker from a working channel to the dead channel to confirm that it's not a speaker problem?

It's unusual that one channel goes dead and the rest work.

How to wire a sony xm-444 car audio amp so that it is a 2 channel 222w amp


Your amp is a four channel so you have 4 sets of speaker outputs. to bridge this amp to 2 channels is pretty simple, all your have to do is when connecting your speakers instead of using both +, and - from the same channel, use the + from the one channel, and the - from the adjacent channel. Do this for both speakers, if you'll notice you now have 2 empty - terminals and 2 empty + terminals, if so you did it right... Hope this helps, enjoy your amp.

Lost channels


What I did after loads of trial & error trying t follow peoples advice on here so not sure how much of it you need t do (Stage 2) might not be neccessary so try 1) followed by 3) & 4) first ;o) :-

1) Deleted all the channels & reset the factory settings to 0000.
Turned off the box at the plug, left for a couple of minutes & turned back on

2) I reinstalled the software at http://www.4shared.com/file/76886028/fd4ac296/GTRom_the_box_Super_8102e_081129.html?err=no-sess (Not sure if thats necessary but I did so try this if 3 & 4 dont work without reinstalling)

3) Turned on the Box & went into the menu pressed 1570 on main screen to get into the CAS SASTEM & turned the EMU key ON

4) Reinstalled the channels using Telewest (Even tho I'm with Virgin) & voila, it worked & I can get all the channels again ;o)

Good luck - Stace

Dont have wire schematic to hook up american pro bass machine limited edition model 1406,need to know how?


You should go to www.the12volt.com they are very helpful and pretty much have a schematic for every single car audio situation and they give you all your options. If they have nothing go to crutchfield.com and go to the learning section then subwoofer and amp wiring. It all depends on the subs that u wanna hook up to it as well as the ohm impedence and the amount of voice coils and so forth they have all of that.

Legend Amp hook up manual.


Pretty Straight Forward get a 8 or 4 gauge amp wiring kit.

Run your hot wire to the +12V from the battery make sure to install the supplied inline fuse near the battery don't connect to the battery until installation is complete.

Run the REM to your stereo power ant. Wire. if available.

Run the GND to Metal Chassis Ground keep it as short as possible.

Run the RCA Cable from the back of the Stereo to the RCA Inputs or Low Level on the amp.

This amp is 2 Ohm Stereo Stable which means you can connect 2 (4 ohm) speakers in parallel to each channel or 1 (4 ohm) speaker on each channel or you can connect 1 (4 ohm) Speaker in bridged mode.

There are other speaker configurations you could use but you cannot drop the load below 2 Ohm in stereo mode and no lower than 4 ohm in bridged mode.

Hope this helps

Polk Audio RC55i In-Wall Surround Speakers (can't hear whispers)


I'd make sure that the receiver surround mode is set for one of the digital settings, such as Dolby Digital or DTS, and make sure that you have the center channel level adjusted to a level similar to the other two front channel speakers. I've seen/heard this happening when using dolby digital material & having surround set on something like 'hall' or 'stadium' or dolby surround, where only 4 channels are used & the amp has to 'mix' sounds to the left & right front speakers. It'll often sound like the actors on screen are talking out of the bottom of a barrel, with a hollow & tinny character to the voices.
