New member with Pioneer headunit woes!!

[Mahnameisjerik0]

Today I installed a Pioneer DEH-1320mp to replace a cheap head unit thats 4x40 watts. I'm running a 10" active subwoofer on the pre-out, and the head unit is powering two kicker 3.5" 2 way drivers on the dash and two pioneer 6x9 3 way on the back.

Here is the problem with my new Pioneer headunit at around 45 of 62 of the volume the speakers sound like they are deprived of power and sound like they are almost cutting out (its hard to describe). But with my old cheap head unit I was able to turn the volume up to almost max volume and the speakers would not cut out.

The settings on the pioneer headunit is as follow: -6 bass, -3 mid, +3 treble, loud setting off.

I just don't get what is causing this.... //content.invisioncic.com/y282845/emoticons/crying.gif.ec0ebefe590df0251476573bc49e46d8.gif . Could it be that my 12v line that's powering the headunit is too thin? (It's pretty **** thin.)

any help would be appreciated.

thats called clipping It means, get your self a ******* amp if you want more volume with less clipping.

what exactly do you mean by 30 loose wire??? and crossed wire as in reversed polarity??

Then can you explain to me why my old head unit didn't clip and was noticeably louder than the new head unit that I just got?

what was the old head unit? power can be an issue, use the fade and ballance to rule out any cancellation issues. it should be noticable as you adjust, it would be louder unballanced if there is a reversed wire

Im 100% sure that I have no reversed wire however when I set the fader to the front the "clipping" stops. So im starting to suspect that my power line going to the head unit is too small.

Also i want to add that the head unit dims when the speakers starts putting out mid/heavy bass... What does this mean?

Thanks

the old head unit was a Denver CAU-420 btw.

Dimming issues are related to your electrical system. Check that your head unit ground is good, tight, and the grounding metal area is clean.
