yep it was the gain it was only up about a 1/3 of the way so i turned it almost all the way down and faded it to the front more and its like it was but no noise. Didnt think of the gain since it wasnt turned up that high. Thanks to all who took the time to help me out, much appreciated.

Ok so after getting off work tonight I looked into it more, and what i found is that it does increase with volume but not til 32 and it maxes out at 35 (i dont normally turn it up past 25), it does get very slighty louder when i rev the car up. The sound is not present while the car is off, and when the hu is in standby. Also I have the hu grounded to the factory ground on the audio wiring harness, and after thinking about it, Im thinking that could be the problem and if not it couldnt hurt to ground it somewhere else. Now is the metal that runs along side the radio compartment a good place to ground it, it runs to the floor so that should be ok, right?

Yes I have done the big 3 and the only new ground is for the rev455, it has been sanded amd makes a solid connection, but is grounded on the same same metal as the sub amp but under a different bolt.

HI guys, I have tried searching for this problem but can't find the answer so here I am. I had recently installed an amp (boss audio chaos rev455) to power my front door speakers and tweeters (power acoustik nb-4). I put the amp in the trunk, because it wouldnt fit under the front seats and ran the rca's and the speaker wire along the passenger side of the car and power wire and remote down the drivers side. When i start the car i get this quiet very fast intermitten noise out of the tweeters. The sound does not increase with rpms, or volume, it stays constant and cannot be heard in the door speakers. Also the speakers that are connected to this amp pop when i shut the car off. I have the grounds for that amp and my subwoofer amp on different bolts but same piece of metal, could that be causing it? I also read somewhere that sparks plugs and wires could be causing this, which the sound reminds me of a spark plug firing, but all the plugs and wires have been replaced and are on tight but if it was the spark plugs the sound would get faster with rpms i would think. Anyone got any ideas what this could be? I have inserted a link to get the manual for the amp if you need more info on it. Thanks http://www.retrevo.com/search/v2/jsp/mytrevo/myTrevo.jsp?page=man

Sorry guys i got one more question, with the amp as stated above it has a level adjuster, its starts out (clockwise) 1, .5(BTL), .3v, 6, 4, and 2, Now im thinking this is to match the hu's preout voltage. correct? And since the hu's preout voltage is 2v, then the level adjuster should be set at 2. Am i correct on this?

Ok thanks thats some good info, you guys really know your stuff, I'll put it in stereo and leave it til i can get a better amp. Again thanks you really cleared this stuff up for me.

Ok now is that 200 watts divided between the subs, meaning each sub gets 100 watts or is each sub getting 200 watts? And yes i have been thinking about upgrading to a mono block around 650w rms at 2 ohms or just get another one of these amps and just bridge each sub into them. Gonna depend on which ones cheaper. Eitherway should get me to about where i want to be shouldnt it? The only issue is that my lights dim pretty bad during bass drops already and the big 3 has already been done with 4 gauge wire. So i dont know if my alternator can handle an extra amp or a bigger one for that matter. And i got a little story for you guys, so when i bought my car (98 v6 mustang) the system i have came with the car, and after having issues with it working one day and not the next, i decided to check over everything and opened the inline fuse on the power wire from the battery and noticed that whoever owned the car before me (must have been cheap and/or just plain dumb) somehow used an 8 gauge wire as a fuse and the fuse block was melted. So i cut that one off and put in an 80 amp fuse block (i had lying around) and never had a problem again. Im suprised the thing didnt start on fire it was like that for a month after i had owned it and god knows how long before that.

I have 2 sony xplod 10 inch 1200w SVC(330w RMS, 4ohms) subs in a sealed boxed with a sony xplod 1000w 2 ch amp. Specs on the amp Model Number: Xm-1652z 165w rms x 2 @ 4 ohms 200w rms x 2 @ 2 ohms 400w rms x 1 @ 4 ohms OK so i have the subs hooked up to the terminals on the box normally (+ to +, - to -) but i bridged it to the amp. Now my question is since i put both the postive wires from each sub directly into the bridge (BTL +) postive on the amp and the same with the negatives, would that be series or parallel? And would it be 2 ohms or 8 ohms, I know it should be 8 ohms on a 2 channel amp thats not 2 ohm stable bridgeable with 2 4 ohm subs and if it is 2 ohms how has my amp been able to handle this? its been like this for about a year now and hasnt had any problems, I'm bringing it up now because I wanted to see all the different ways to wire subs but i havent seen anyone do this so wondering what you guys think. Thanks
