I am running a 200ix oldschool rockford amp to two kicker comp vr's. Whenever i try and give the subs more than a little power they distort and bottom out really bad. I dont know if they are blown or what. Please reply with any feedback. The subs also get outside interference ....like a buzzing. I have run the subs to the amp bridged and non bridged but still they distort really bad.

also, i have tried a ton of ways to fix this. i have checked and re checked the connections of the subs, amp, ground, batt....everything i am just stumped. i think, at this point that the subs are blow,. i am running this off of a kdcx 469, i know that the filters and crossovers are set correctly too.

more that a little power... Are you cranking the gain right up? Do you have the bass boost at max? What is the power rating of the amp and subs? How old are the subs? What size are the enclosures and subs?

the gains are about 3/4 of the way up and same with the bass bost. I have them in sterio mode and all they do is distort like crazy. they arent very old and i know they arent blown because i itested them on another amp. I am getten crazy interferance from somthing as well.....engine noise but i have had my ground in three different places all of which have given the same interferance. My rca wires run down the left side of the cab and my power wire runs down the right side so i know that they arent causing interferance with eachother. The only thing that i can think of is that i dont have my antenna adapter yet so my antenna isnt plugged in..but would that be causing the interferance. I have also gone back and doubble checked every connection and re-taped all of them ground, power, inside the box for the subs, remote. The subs are 8 ohm subs but in sterio mode my amp runs at 4 ohms.....is this a problem? I wouldent think it is but this is only my third system install so i am not really familiar with what subs can run off of different amps. Please help i am STUMPED.

If I get a problem like this, I always go back take everything out and install it again, checking everything really good, check your rca's and everything, plug your antenna in also

Is your rca wires running next to your power? this can bring in a lot of interferance. Also is it hooked up to after market head unit. For example i know in some exploreers there is one sub in the system and if you try to hook up the rca adapter it wont work. Hope this helps.

I already said that they run on the opposite side of the car from eachother but i did fix the problem. The alternater was sending carzy engine noises through my lead wire. i insulated the lead wire and taped any possible part of my lead that was showing. The interferance has stopped and i am getten plenty of power. thanks

OK i have a punch 200ix amp pushing two kicker compvr c12 8 ohm 12's. The amp is 4ohm stereo 2 ohm mono. I run the subs in stereo. I dont know what the problem is but whenever i have the gains equal liek 3/4 of the way up the subs make a wierd knocking sound and dont bump at all. but if i keep one of the gains up and turn the other one all the way down one of the subs goes quiet and the other one bumps really hard. i dont know why this is happening but i would sure like if sombody offered a solution. also i dont know much about the amp so if anyone has one or knows anything about it please let me know.

OK, first of all, the Kicker Comp VR is a DVC 2-ohm speaker. Where did you get 8-ohms? Secondly, what are you setting the gains to? Why are they up to 3/4? What you are seeing is the amp overdriving, either from gains way too high or speaker load way too low, or both. Punch series amps are not 1-ohm stable. The amp is not, as you state "4-ohm stereo and 2-ohm mono." It's the other way around. With DVC 2-ohm woofers, you must wire them at 4-OHMS for them to work in stereo on this amp as it requires a minimum 2-ohm load and you can't do that with a DVC 2-ohm driver. It requires a minimum 4-ohm load in mono. Now, if you speakers are indeed 8-ohms, then wire them in parallel and bridge the amp for a mono 4-ohm load. Set yur gains to match the input, don't just "turn them up" to see what happens, unless you plan to buy a new amp or new speakers fairly soon.

That is all information that i have been told......the speakers say 8 ohm on the back so i am pretty sure that they are 8 ohm speakers...... . I fixed the problem tho i reversed the connection on one of the speakers and it pounds. that amp is great i can run it for houres and it doesn't even get warm.
