Problems with sub cutting out

[drekati]

Hi,

Setup is as follows (installed by audio express)

Mazda 3 with stock head unit

Rockford Fosgate 3sixty 1.0

4 channel pioneer amp which power the following

-two pioneer premier 3 ways

-one 10 inch sub

I have an ipod plugged into aux on 3sixty unit.

Recently Ive noticed the sub is a lot lower and sounds off on songs.

I have to crank the volume on the ipod and the 3sixty switch to get the sub to hit.

It is not a subtle change in volume of the lows either, it goes from no lows at all to .. boom.. full on bass.

If I crank the volume the bass sounds fine, but at mid volumes its too low and distorted, and at lower volumes it sounds off (but its not completely off as I jfeel a small vibration on the woofer.)

When I play rap or low end bass songs it seems to keep the sub running fine, but rock or jazz with less low end sound like the sub is off altogether until a low end part of the song kicks in.

I took it back to audio express, at first they said it sounded fine to them. Then they blamed it on poorly recorded mp3's (which is BS as i rip at high bitrates). I then recreated what happens and they said i should get another amp specific to the sub (not sure why it was working and sounding fine the week before).

Then they said its likely the 3sixty unit (the volume button the aux on/off does not work all the time) and said they would have to replace the 3sixty.

Any ideas what may be going on here? I'm getting mixed messages from them.

Thanks for any help you can provide.

more than likely it might be the 3sixty, ive heard some bad things about them, but have never personally owned one. my advice is dont spend any more money at all on anything untill someone here can verify whats goin on.

some audio shops dont have a clue how to tune or setup eq's or amp's, so you get a shitty sounding setup, you take it back, they rip you off again, and it continues. so, in that, id say do not go back to them.

maybe unhook the 2sixty and dont use it, just run the rcas from your headunit directly to your amp and see if that sounds better. the settings on the 3sixty may be whacked out or it may just be defective. i dont know anything about the 3sixtys settings or anything like that, so thats why i say wait until someone else verifies what the problem is.
