Speaker wiring problem with new speakers

Hey guys I need help!

I am having an issue with my new speaker install. If you could be so kind to offer your thoughts it would be much appreciated...

I have a 2011 JGC Overland (10 speaker factory system). I've recently done a complete replacement of the entire stereo system with one exception: the speaker wires running from the factory amp wiring harness to my doors have not been replaced. I used those factory wires to get the signal from my amps to the new door speakers. I snipped the speaker leads coming out of factory amp and connected my rockford fosgate amps to those leads going to all the door speakers. Then once I removed the factory speakers I plugged in a Metra 72-6514 Speaker Wiring Harness to the remaining factory speaker wire harness at each door and connected my new AF speakers to the wiring harness.

I'm having an issue with my rear speakers that I installed recently (Audiofrog GS62 coaxial). They play but they sound like shit. Really tinny like there may be a bass blocker or something. Both right and left sides sound this way.

I've done a bit of troubleshooting swapping amps and RCA cables. I have narrowed it down to something beyond the amps. The trouble always stays with the wires and speakers in the rear. When I connect the rear speaker wires and speakers to an amp channel that is putting out good sound to the fronts the problem still exists. So I'm thinking it's something in the wiring going to the speakers. Or I guess it could be the speakers? I don't really think I could have blown both of them or received two DOAs but I guess it's possible.

Do you have any thoughts? Do you know much about the factory rear speakers and wiring? Is there a bass blocker connected or something in-line?

I'm looking at my factory speaker that I took out and it is not a coaxial. It is just a 6" woofer. And it doesn't look like there is a bass blocker built in to it but I can't tell for sure...

Please let me know what you think. I'm scratching my head at this point...

Re: Speaker wiring problem with new speakers

OK. After looking at the wiring diagram on wk2jeeps I see it showing a "Splice SX296 X296" along the path of the wire between the factory amp and both rear factory speakers. This splice is not shown for the front 6x9s but it is shown for the tweeters up front. Any idea what this "Splice" means?

nookie - please let me know if you try that. I am very curious. I will be out of town for a couple days and will have not further time to troubleshoot until the weekend...

Re: Speaker wiring problem with new speakers

Greetings,

Sent you a PM.

The possibility of the 3.sixty.3 during setup could have blown the speaker. Make sure you have the latest firmware for the RF.

Best for now.

Re: Speaker wiring problem with new speakers

Update: I connected one of my old factory speakers directly to the amp channel and it plays perfectly. So the problem has to be the wiring or the speaker.

They both sound the same. I'm hoping I didn't blow both of them during the processor setup :/

I am running new speaker wires to the rears tomorrow and I'll definitely know what the problem is then...

I will report back here.

Re: Speaker wiring problem with new speakers

So it was determined today that I blew both rear speakers setting input gain levels set for my 3sixty3 :/

The good news is Crutchfield is sending me a new set

So my belief now is that the factory speaker wires going to the rears is full range and does not have any bass blocker...

Greetings,

Technically, it is not a full range signal for the rears, but bandwidth xover configuration. The signal starting point some where around 80hz (cycles). The AudioFrog is from 50-20k. In theory, you should have had no problems.

The problem is that the DSP, 3.sixty.3 is accepting the 4volts from the HU to hot and it easy during the configuration setup to miss that detail. The instructions for the RF do not give any notes regarding this issues nor give any good information on the configuration.

So for all intestine purposes, it is best when dealing with any DSP unit, consider all signals as full range and adjust according to the parameters of the speaker before going into the live output stage. It takes less than a second.

Best for now.
