one of the many reasons why i've never ran anything but a front stage in all my vehicles

sounds like you are on the right track with everything. i'd definitely put that time alignment feature to use!

 

Hi!

Yep, that will be first, since it is by far the easiest to do!

 

if you are running the rears off the HU, they are not connected via RCA's, but rather standard speaker wire. Find the wiring diagram for your HU, and check the polarities. Reversing these could cause the "veiled" sound. It basically inverts all frequencies...sound funky.

Damn

Thanks, John!

 

Depending on your installer, they might have used an adapter from the Honda harness to the Pioneer harness of the HU. Some prefer to cut the Honda harness and re-solder straight into the Pioneer harness (more time / less clutter). If you pull the unit out, if there is a baby blue harness, that is the Honda one, and they probably used an adapter.

I would take it to the installer and ask him to explain the muffled or "veiled" sound, and why it is doing it. If they installed it, there should be a workmanship warranty on their job. I would not pull it out, unless you installed it, because if they find out you pulled the HU, they might blame it on you.

The installation of the amp should have nothing to do with the rear channel, other than the sound quality of the fronts might seem like it is making the rears sound worse, because the fronts sound that much better.

Did the rears get worse after you installed the amp?

This amp, yes. But I do not remember this bothering me with the Memphis amp...of course with THAT amp he may have had everything wired correctly

I can use a polarity checker or pull the speaker wires out of the amp, reverse both sides and see what happens when I then blend in the rears....

I'll fix this one way or another!

 

Are you having problems with the fronts or the rears? I was assuming it was the rears, because you said it clears up when faded all the way forward. This would point towards the rears as the "veiled" sounding speakers.

John

 

Can't tell

If the fronts are in phase with each other and sound OK alone, and the rears are in phase with each other and sound OK alone, but the fronts sound weird with the rears, there's no way to tell by listening which pair is polarity swapped.

And this still may be a time align issue..........I just need to get in there and start checking.

 

Nsxnext1 (aka Art ) is going to use a polarity checker on my speakers...."pop"
them and see if the speakers go out or in....MUCH easier as a first step than me removing anything!

Art is the MAN!

Stay tuned, all. I will let you know what we find, though it may not be until Monday.

if they sound alright by themselves, chances are that they are aligned correctly. You can test them yourself. If you have a bass test CD, go to the Thump track. See if it kicks in or out. Sounds like a phasing problem to me. Sounds like the rear signal is hitting your head faster than the front signal, so you are kind of hearing the same thing twice, thus creating a sort of veiled sound (your ear thinks its one signal, and tries to process it as such, but the time align is slightly off). Does your head unit have a time delay funcition? If so, you may want that tweaked.
