10" Fi Q question

I'm sure. I tested my IPOD directly to the amp to verify it's not the signal going to the amp and I tested a different sub. All possibilities resulted in the same sound. Only thing I didn't do is change out the amp. Now, I didn't always get the sound at first on my Fi. If it wasn't doing it, and I changed the volume a little, it started making the sound again. Maybe when you tested the other speaker on the amp, you didn't try that to get the sound. Or maybe we have similar problems stemming from 2 different causes.
I think what happened to my amp, is when I first moved from Michigan to Texas, my engine died on my car after 152,000 miles. So I bought a new car, but didn't have my tools down here yet, so the dealership unhooked the amp and all my wires for me. I would bet they didn't disconnect the amp in the right order since I haven't used it since then and all of a sudden it isn't working.

well i didn't play with the pionner sub a lot, i just realize there was no noise then i disconect it.

The symptoms are like yours. At first i tough the wire was getting the the way. Once i'll have some free time (alway at job or university) i'll do some more extensive testing. When i hooked it to my kicker 200.2 at 4ohm bridged the problem wasn't there for few second, but as i put the volume louder it came back //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

What are you gonna do? swap amp?

Sort of. I'm gonna buy a new one. I don't want to destroy my beautiful brand new sub for a Hifonics amp. Gonna go with either an AQ1200d or an eD NINe.1, whichever I can get cheaper.

See, I told you that you have to play with the volume to make it come back! Are you getting the noise from 2 different amps or is it the same amp both times?

But I'm guessing that's why my Q wouldn't get as loud as it should. Seems like as the gain or volume increased, the signal output had multiple frequencies coming out. My DMM moved a lot more than it should and wasn't very steady at all. So when I got to around 23 volts or so, it started having intermitent higher signals sending the amp into protect mode. Something with the signal output transistor is probably bad.
