Question about Sony XM-2200GTX Car Audio Amplifier

1 Answer

Help!!!! Hi, I have recently connected sounds throughout my car. When my friend put in my Headunit, it blew me fuse in the car. My amp and sub were working fine. When we went to check the fuse and fix the problem we found that my friend had hooked my Earth behind the head unit to a wire. So we cut that wire and grounded it and then my lights were working fine. THen we noticed that my amp wasnt working. Everytime that the headunit turns on the light oin the amp goes from the green into protection mode. I was wonderiung what has happened. We tired my friends amp with the same set up and it worked fine.

Re: Help!!!!

Check your ground wire! Relocate it to another place in the car and try to get a heavier ground wire aswell.

I just recently bought a brand new MTX magnum amp and dual 10" enclosed subs deal off of amazon. They arrived today, and with the help of a friend who is good with car audio systems, we set the whole

the best thing to do is get in touch with amazon,and see what they can do about it,if you try to fix the problem yourself it will invalidate the garantee!

First, test your sub terminals for an Open connection, or no resistance. This is to test if your sub is blown. This is usually the case.

Double check your wiring, not only to the sub, but from your headunit to your sub. Make sure your headunit is configured to work with your amp, if you have a setting for this (for instance, SUB: ON).

Amp not working

It sounds like you either blew a fuse, or you cooked your amp. The fuse on the P200.2 amp is a 30A fuse, and it sits right next to the power, ground, and remote wire connections on the end. Pull the fuse out and see if it's blown. You should also check any other fuses that you have in the car before the amp.

Amp comes on but no sound to the subs and i think i checed all wires and even got new rcas

Hi mate

I know loads of ppl who have had the same problem.
Are you getting an output from ur headunit RCA's? Sometimes you need to turn the sub RCA's on via ur headunit. I would make sure im getting an output from the headunit first.

Subs and amp dont work

His amp probably blew your fuse. Check that you have 12V at the power connections. If you don't, then find the fuse in your positive wiring to the amp. If you do have 12V to the amp, check your remote power up also has 12V between that and the negative line when your head unit is on. If it doesn't, then it's probably an internal fuse in your remote switch on line inside your head unit caused by a fault in your friends amp. This is normally accessible at the back of the head unit.

Blown fuses

there is a possibility that the current load is excessive nor there is a short circuit from elsewhere, do not try to install again a new fuse unless you are certain there is no shortages of any wire from inside the amp and throughout the system by physical inspection

also install the right value for your fuse meaning the right amp and voltage, high temp is an indicator of shortages and defective power transistor

Amp works but no sound from sub

Some older Pioneer radios require you to connect the Subwoofer RCA to the rear output on the back of the radio and then you have to turn on the subwoofer in the menu on the radio. What model Pioneer radio is it? Also, make sure that the RCA plugged into the amp is on the input side, not the output side.

Subs will go off the wall with bass, but not in tune with music.

hi, first disconnect the rca input, then switch on headunit and if the amp produces a constant bass thump it then means it has an internal fault. if the amp idles quietly then replace the rca cable, or try connecting the headunit lineout feed directly to the bass amp, in this way you cud find out if your fault is coming from the headunit or the equaliser. cheers
