crackling speakers

What year Camry?  (complete info always helps.)Support the12volt.com

2005 camry xle with jbl system and navigation.

I believe a Metra 71-1761 will work so you can keep the factory head, steering wheel controls, etc but wire your new amp in place of the factory amp and replace the speakers.  Actually it is not that simple.  To do the job correctly is a fairly complex installation and will require rewiring speakers, etc.  If you're not up to this I suggest taking to car to a competent local car stereo shop.Support the12volt.com

What do you mean by rewireing the speakers? They have all been replaced and i ran 2sets of speaker wires to each speaker, 1 set from the connector that runs to the factory amp, and 1 set to the speakers, so the wiring may already be in place. Im up to the challenge (maybe with a little guidance). I take it that its not as simple as using the outputs from the hu to the factory amp as my inputs to the loc? Thanks for the help.

I just took a look at the wiring diagram for this car, and i notice that from the head unit to the amp, there are only 4 signal wires, all positive, 1 for each speaker. What does that mean for this task?

Hi.  The signal from the HU to the amp are line level signals.  The four wires you see are the positives, the negative is all common and usually carried by the shield.  You would need to adapt these to RCA connectors to plug them into your new amp.Support the12volt.com

Sounds easy enough.

Looking at the wiring diagam, the signal wires from the hu, are, and this is hard to explain, but they are circled around in a cylinder shape with dashed lines. This is connected to one wire on the hu labeled SLD. I assume this is the shield, would i connect this to the shield of all of the rca cables? Using this, i wouldnt need the loc, and should be good to go right? If my assumptions are correct, it seems pretty straight forward. I look forward to getting another whack at this car during the weekend, but ill never touch another camry if i can help it :)

SLD is the shield, and yes, it'll be common to all four of your RCA inputs. Bypass the factory amp completely, and if: a: the noise is still present while running the aftermarket amp with an off-board signal source, then the issue is in the speakers or wiring. or b: the noise is present with the OEM head driving the amp, and a: (above) does not apply, then your noise issue is in the OEM head unit.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

its not the camry, its the fact that its a jbl system. its the same way in a sequoia but once you realize what is really going on then its not that bad.
