problem with kicker subs and 200ix amp

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.

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?

what size cvrS???? b/c i  had 2 12s and i put well over there rms and didnt blow em... i put over 600w 2 one of them and it pounded

I have 2 kicker comp cvr's 12's with a kicker kx 800.2 that pushes 954 Wrms and have them on a 2ohm load and havent blowed them yetlive in your world, come play in mine

damn nice.... maybe it was my box.... (bandpass)

mine are in a sealed box, never liked the bandpass, I dont like the sound they put out, use a sealed box, live in your world, come play in mine

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 alsolive in your world, come play in mine
