View Full Version : Factory Amp
11-09-2008, 08:04 PM
Hello, I have a 2001 gt with the monsoon system. For about the last year I have had no sounds at all in my car. The last time I listened to music it all the sudden just cut out. The only thing I ever noticed that may have caused this was that I had a steel fishtape (a tool for pulling various kinds of cabling) in my trunk and it unrolled about 1 foot of slack that was magnetically stuck to the bottom of one of my rear speakers which possibly tapped the +/- inputs on the speaker. Maybe this shorted something out? The headunit works fine, the EQ dances like music is playing, but i get no sound at all. I was thinking it could be the amp, is there a way to test it?

Check all your Fuse's? I'm just guessing though.

Yah, I checked the one in the driver side door fuse box and the one under the hood and they are both good.

isn't there a fusebox on the passenger side also?

There is a fuse box on the passenger side as well, but none are labled as amplifier only radio and that fuse is good. The only place I found a fuse labled as amplifier was on the driver side, not under the hood or on the passenger side. Am I missing checking a fuse somewhere?

i've seen headunits go bad, as in not producing sound.. and still power up and everything else.

Nah, it's producing sound. I work telecommunications and have a device that detects noise coming across cables and I can hear music coming out of the harness when I unplug it from the amp. Trying to find my multi-meter now and check to see if power is getting to it. If all else fails I guess I'll be hitting ebay up to find a new one or does anyone here have one they wanna sell if need be? I maintain phone systems for a chain of about 12 dealerships and my discounted price for the amp through them is over $300, over $600 undiscounted. What a joke, for 600 I could install a decent aftermarket system with subs.

I think I still have the monsoon amp from my factory stereo...don't think I sold it yet. I'll check when I get home. If I've still got it I'll send it to ya for $30 + shipping.

Well, I ran a multi-meter on wires E11 and E12 (although in the following post they are both labled as E11) which according to the following post are the positive voltage wires and I am getting 12 volts on each and music is coming thru the harness, but not out the amp.

This leads me to believe the only thing left that it could be is the amp so I am in the market for a replacement. SSRacer if you still have yours I will definitely buy it or if anyone has got one they wanna sell. Also, I'm open to any other suggestions on this, but I think it's pretty much narrowed down to the amp.

I do still have mine. I'll post a couple of pics of it when I get home tonight cause I'm not sure if they made any changes to the amp from 01 to 02

As far as I have seen there has been no difference in the amp in any of the early 2000 models. The amp I took out has a model number on it of: 22674744 So, I guess if you got the same then hopefully I'll be listening to music again soon :P

Yup, that's the same model. PM me your email and address and I'll send you a paypal invoice. Call it $38 shipped?
