Amp output voltage very low?

[QUOTE="CaptNKILL, post: 4375587, member: 579103"] I've checked everything. My balance is set centered, my fader is all the way to the front (I don't need my rears), my polarity\phase is fine, I tried the crossovers on the HU and the amp at 80, 60 and OFF without any real change. I thought maybe the amps weren't getting enough juice for some reason (only running 312w rms for my sub right now) so I checked my input voltages on both amps and at my normal listening volume with the car running they are getting 14.1v. So it isn't a lack of power. All I can think is that the amp is having some sort of problem or maybe that 70w is ridiculously loud for me and I'm simply not turning the gains up enough... which I highly highly doubt. The highest I got the voltage to read was 7.5v while playing a 1000hz 0db test tone at a volume of 27. Normal music makes my ears bleed at that level. I emailed Kicker about it a little while ago, so hopefully they can give me some suggestions. I think I might try out a friend's amp tomorrow to see if the speakers sound any different or the voltages read correctly. If the speakers have better mids with his amp and the voltage reads fine then I most likely have a malfunctioning amp. I have to say, I've been really surprised how little information there is around the web relating to low voltage readings on speaker outputs. It seems like either no one actually bothers measuring with a DMM or no one has the problem. [IMG]//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif[/IMG] Is there any chance that it could be my RCAs? [/QUOTE]
