MTX Terminator Amp Issue
I'm having a problem with my 600W MTX Terminator amp, when I turn my stereo on, it hits twice, then three red lights flash on top of the amp, at first I thought this was ground issue, so I used an actaul sander to sand down the ground spot to remove any and all paint, and refashioned the ground wire to the spot. That did not solve the issue.
Next, I turned my stereo on, and unplugged the remote wire from the amp while the stereo was on, then when I plugged the remote wire back in, the red lights stopped flashing and it worked. The issue is that I have to do this every time I want to listen to my subs. Are there any known solutions to this problem? I'd appreciate any and all constructive feedback, thank you! - Austin |

Re: MTX Terminator Amp Issue
How old is the amp?
What type of wire are you using for your power, ground, and remote? What type of deck and how old? Has this set up been installed in another vehicle previously? |

Re: MTX Terminator Amp Issue
Your power wire should have an in-line fuse, double check that it's good and the fuse housing is screwed together tight. How is your remote wire tied in?

Re: MTX Terminator Amp Issue
The inline fuse for the power wire is about a foot away from the battery, it isnt burnt at all and is still intact. The remote wire is connected to the head unit via wirenut. It's just one of those little blue remote wires you buy in a walmart amp kit. Do you think I need a thicker gauge remote wire? Like I said, if i turn the system on, i get flashing red lights. To make it work while it's still on i have to take the remote wire out of the amp and put it back in, then the subs will work until i turn the car off again, adjust any frequency or bass boost settings on the head unit, or switch to a CD.

Re: MTX Terminator Amp Issue
do you have a multimeter ? if so, check the voltage of the remote wire at the amp when the cd player is first turned on, then check it again when you disconnect and reconnect it.

Re: MTX Terminator Amp Issue
Okay, I'll have to borrow one. What kind of readout should I be looking for?

Re: MTX Terminator Amp Issue
I'm not real familiar with the newer pioneers. I'm guessing since you say it's connected to the head unit with a wing nut that there is a specific connection for the remote wire. On the older pioneer head units as many others there never used to be a remote wire terminal. I always spliced the remote wire in with the acc. on the wire harness. I would try that.

Re: MTX Terminator Amp Issue
Looking at the picture from pioneer's website of that model I don't see anything showing where you would connect the remote wire with a wing nut. Do you have a picture of where you have it connected to the head unit?

Re: MTX Terminator Amp Issue
Sorry I didn't read it that close and thought you said wing nut not wire nut. The acc wire should be either yellow or red, it should be labeled acc. If there are two red wires the one with the in-line fuse will be your normal 12v power the other red would be your acc, but they normally make the acc wire yellow.

Re: MTX Terminator Amp Issue
Pretty much universal color scheme for headunit wiring
ACC = red const 12V = yellow orange = illumination solid blue = auto antennna blue with with strip = amp turn on Please do not use wire nuts in a car, they are for 110V AC house use. Houses do not have vibration like cars do (except during earthquakes). Either use a butt splice or twist and solder then tape or heat shrink over it. That may actually be the problem, voltage drop acsross that connection. The voltage between ground and the auto turnon on the amp should be close to 12V. After looking at some of the posts make SURE you used the blue wire with a white stripe and NOT the solid blue one. |
