Default so i hooked up my new amp and.......

i hooked up the aq2200 i just got from someone on here and im not sure what the problem is or if there is even a problem.. the thing with it is that it seems to have barely any power pushing my fi btl untill i turn the gain on amp all the way up and xover all the way up. my memphis mc100d pushed it better on the same setup (rca's and speaker and audio control line driver)
was i just expecting too much or is there a problem anyone can think of?
it also has a constant vibration sound through the sub like a bad ground but all my grounds are done right and when i wiggle the rca's on the amp input i get a bad noise through the sub.
any help or thoughts would be great.
if you need more info just ask.

is the sub moving without any signal being sent to it from the headunit? if so does it look like its kind of bobbing up and down like its floating on water?

and when you wiggle the rca's can you describe what kind of noise you here through the sub? and did you change out the rca's and find out if that was the problem yet so you can rule them out?

the sound is on when i pause the ipod or cd. when i wiggle the rca's it makes a high pitched "squeeling" noise, i guess thats the best way to describe it. i ran out of time to try a diff set of rca's but i will try to tomorrow.

the sub doesnt move much but you can hear it and feel it if u touch the sub

This is kindof my go to answer;

I think your RCAs are not grounding.

With the RCAs plugged into the amplifier take a 18ga or so wire and connect the wire to your ground and then touch the outside metal ring of the RCA with the other end of the wire while you have the stereo playing at 1/3 the total volume on the deck.

if it gets louder when you touch the wire to the outside ring you will know there is an issue with the signal. {either at the deck or at the amp}

another way to test it is to grab an ipod and a headphone to RCA converter and use that instead of the deck.

yes it is definatly an rca issue. and if its not external but internal on the amp then that new amp you got is bad homie. only way to find out is to do all the external tests on it you can to see if that solves the problem first.

Sounds like a solder connection within the amplifier.

shouldn't have anything to do with it, but I wouldn't suggest keep screwing with them. I would pop the amp open and look for lose/shorted connections. gonna have to have a patient eye though
