With an input of 8V I can easily set gains to produce 69v at speaker terminals, full gain produces approx 110v (and the amp hums quite loudly)

Thank you for that info. I will run that test and get back to you.
BTW when I said 10v AC "on one channel" i meant on the RCA inputs to the amp - not it's output.

Ok bit of an update for peoples thoughts. At this stage I am trying everything before removing the amp and sending away as it is not a cheap or quick process in Australia apparently. I measured the input signal to the 1200.1 using a 60hz test tone - went up to 10volts on one channel only. So i insta...

No didn't use AudioControl with Alpine deck.

Next step will be removal and inspection of amp.

I borrowed an old Alpine deck and temp wired that up to the amp. With amp gains full and headdeck volume on full it would run the sub hard. I have the sub installed, Audiocontrol pre-amp input and output gains at full, added some boost via equalizer tuning, xenon gain full and lpl44 turned up bout 3...

Ive tried switching rca inputs, and channels around, using only 1 rca lead, adding a Y adapter, removed working RCA from running front stage amp then plugging into PG etc. But still no good, its as if the line driver has made no difference, but that is working on my other amp.

Audiocontrol unit states max peak output of 14v.

Ford fairmont 2007.

Ok looking for further advise.
I used an Audiocontrol EQS unit as a line driver and I still have next to no output from the PG. Again tested over all channels etc and it is the same. If I plug my ipod directly to the PG it will run the woofer well still...
Any thoughts?

Ok plugged in my ipod dock to RCA cable directly to the Xenon, fed in some gain and it was firing the sub very nicely - looks as tho I need to boost that line voltage, im assuming the ipod would be feeding 3V at most so a signal of 4V upwards should work nicely. The small amount of noise is still pr...

1v is super low for that amp. xenons need a pretty hot input to reach full potential. i used to run my xenons at about 14v. if you can...throw a line driver in front of it. im very confident it will fix your problems. i always use the car analogy. you can run a civic fine with regular gas (the sony...

Source unit was sent back to manufacturer for RCA mod. Output voltage is low approx 1V but my 4 channel POS sony is running off it fine. I understand a higher input voltage would be better but I don't require the xenon to run at its full potential in this install. Sub wiring has not been touched sin...

I am having some problems with my old faithful xenon 1200.1 and was hoping for some help. When wired up my sub output is very low, this was not the case in my last install with the same equipment, the source unit is the only difference now. With gains on full the sub output is mininal with my front ...
