Odd stereo issue

[KyleRass41]

Never noticed anything prior to this but when I fired up the tunes for the first time in the driveway, the front tower speakers were louder than the rears. Gains are all the same. I do have 1 set to a syndx4 and the other sharing with the sub on a syndx6 I touched the tower and I heard and felt a click and they all fired up together and sounded great.

I have 4 rev 10s and 2 are brand new. Swapped out the 8s. The wetsounds aux port that I added to the eq is somewhat touchy. Seemed fine all last year. Never had a problem. If you wiggle the aux plug it shuts speakers off and on and thought that was the issue. Ive tried 3 different cords and all seemed to do the same thing. I ended up plugging straight into the rear aux on the eq and still same problems but didn't cut in and out if you wiggled it. So I can obviously go that route but thoughts on what would make the rears softer than the fronts? I thought I charged the batteries good but I was charging the cranking battery as I was doing all this. There is a click on the charger every 15 to 30 sec which I think is normal but just throwing everything out there to help fix the issue.

If I let it sit off and replug aux back in and shut the boat off it did work fine right off the bat but then I touched a metal part on the dash and a click happened and the sound all shifted to the fronts again.....

Any help please!

Thanks!

Im thinking theres 2 issues, one uncovered the other. 1) you lost a chnl into that amp driving the pair that was not as loud and 2) the amp is not bridged correctly.

1) make sure the batteries are both fully charged. 2) resolve all connection issues that cause cutting in and out. 3) make sure the amps are bridged correctly, 4) dial the gains with a volt meter. Being 2 different amps, I would not assume that the gain structures are identical. So 40% on one amp may be right, but 40% on the other amp may not be the same output.

Also to mention. One of the older rev 10s mid bass is shot so I am ordering a replacement speaker for it.

Still learning a lot with stereo systems but when you say bridged correctly, what is the correct way to bridge them?

Thanks for the quick response chpthrl!

But you don't think it's a bad amp? Maybe ground or speaker wire short?

In what way? Is this one of the suspect speakers that was not as loud?

owners manual shows exactly how to properly bridge the 4 chnl amp(s). Not done correctly, effects both sound quality and output.

Not yet, but im not ruling anything out. But do want to address the obvious first. A meter on the speakers can flush out a bad speaker or a wire that shorted together or to the tower. Possibility, but I would expect this to put the amp into protect mode. An open would reduce sound to one speaker, but not both, unless two wires to each speaker was cut in half.

If the suspect speakers are on the same amp, is not likely a wire issue to the speakers. its an amp issue or a signal or voltage issue.

No it wasn't. It was a front one and plenty loud.

Dang weather. I'll have to get in there this weekend and report back. Thanks!

[KyleRass41]

Well chpthrl.....it wasn't bridge correctly. Had way to many splitters going and one was loose. Could that have blew the mids on that older rev10?

Chpthrl - as far as the y adapters go, when I was wiggling them the speakers started sounding bad. I switch out a few other y adapters and 1 worked perfectly. Is there such thing as defective adapters? I think they were from Best buy insignia.

[chpthril]

Sure can.
