Thread: Distortion on Aftermarket HU

2004 GP GT2 With Monsoon audio.

I have a Pioneer HU with the GMOS-04 interface. I cannot turn the gain up enough to eliminate all the distortion at high volumes. I know Monsoon isnt exactly the best speaker on the market, but with the stock HU I never have high volume distortion issues.

I know the GMOS produces the "chimes". If I can live with out them, can I wire the HU in directly? Not having a switched AC source is not an issue, I can pop the faceplate off and the only power draw is to keep the clock memory.

There is a gain adjustment on the GMOS-04, it is located on the side of the little box, actually there are 2 gain pots, one for the chimes, I believe that one is on the end by one of the connectors, and the other is for your system. Play with it until you like the sound. That is all.

Thats what I was saying, I can't turn the gain up enough to get rid of the distortion. I went ahead and wired it in directly, I leave for work in a few minutes, well see if it drained the battery too much my wiring the switched lead into the constant.
