      Hi there... in my 1997 Limited with JBL, the front driver speaker is noticeably quieter than the front passenger. I tried swapping the speakers and the problem persisted, so I assume it has something to do with the amp in the back.

      Two questions:

      1. has anybody seen this and do you have any suggestions?
      2. how do I remove the coat hanger clip over the rear passenger door so I can get better access to the amp? I can't seem to make any screwdriver or allen wrench work on it...

      thank you
      Danny

      The coat hanger bolt takes a deep drive sshallow wall socket, only way to get the bolt/screw. It is somewhere around 1/4 or 3/32 for size cant exactly remember.

      Have you double checked your balance settings on the head unit? Might be set all the way to the right instead of in the middle.

      Hi @bobditts, I've checked the balance and unfortunately that's not it... i think it's the amp...
      @974X4BLACKSPORT, i tried every tool I have but while I can get some in, nothing is biting the bolt head, assuming that's what's in there... but I'll look for something with an even thinner wall, and I'll drop by a local car audio shop to see if they have any ideas

      if anyone has any thoughtws about how to debug the amp, I'm all ears (no pun intended)

      Thanks again

      I’d think that bolt would be metric. As cheap as aftermarket head units are these days, I’d slap a new on in before trying to fix the 20 year old factory stuff that is marginal at best.

      That bolt might be the odd 5.5MM...

      Thanks, @Mbrooks420. I was planning to put in an aftermarket headunit, but I thought the easiest way to do that is to connect to the existing harness. But since I have a JBL, I think that harness uses the amp in the back, which, in turn, is wired to the speakers. If I bypass the amp, I think I have to run wires from the new headunit to all of the speakers, including the subwoofer in back. Am I mistaken?

      @toypaseo, I'll try to find that size.. I'll look on amazon unless you have a better suggestion.

      Thanks again

      FYI, This is what I used for my 97 Sport on the coat hook bolt to be exact: 7/32", O.D. = .345" x 3" long

      I believe workforce is a Home Depot brand.

      thanks, guys! My plan is to get access to the amp in the back and see if I can just play around with the connectors in case one has gone bad and can be "jiggled" back to life. It's a long shot. If so, then I can get a new head unit that leverages the current system. If not, then i'll be digging around these forums to see what others have done...

      Has either of you replaced a JBL without using the installed amp, btw?

      thanks again
      Danny

      If I was upgrading, I’d replace it with a cheap aftermarket amp, and probably the sub as well. After 20 years I’m surprised the factory paper woofer is still kicking.

      Thanks. Do you know if that means I need to run all new wires to the speakers?

      There’s a harness back there that you can splice together to bypass the factory amp. For the amount of power you’d need you could almost surely repurpose the power and ground or the factory amp IF you decided to replace it with something else.

      There is also the option of running just an upgraded power wire, and RCA wire and running a smaller 5 channel amp mounted behind that panel. You could then wire in all the factory speakers to the new amp. There are some fairly small, cheap 5channels available.

      @Mbrooks420 thanks!! I thought the speakers were connected to the amp in back, but now that I think of it I think there are harnesses that go in back and bypass the amp... so I think I should do what you say. Thanks again!

      I just picked mine up from Autozone, since they had it in stock, https://www.autozone.com/ratchets-s...uralast-1-4-in-drive-5-5-mm-socket/557467_0_0

      Not the best price, but I was planning on needing it quick. I would definitely buy one if you plan on working on your Explorer. I've only used mine maybe five times, but when I figured out that's the size, I had it already. I do think the impact version of it would be too thick in some spots where I used mine though, and I don't recall ever thinking I needed the impact version either. That one you posted pry would be fine.
