Default JBL Comps Crossover Rusted, What to do?

Hi Guru's,

My JBL GTO 607c Components crossovers were placed inside the door using the double sided tapes 1.5 years ago. With the double sided tapes giving away they fell down to the door bottom. It seems that the water has entered in to these and the terminals are rusted. Even I am running the using the current setup which is working fine. I don't see any disturbances due to this. I have even upgraded to Pioneer P80 HU and they are performing well, but in my next upgrade I have to connect these speakers (through x-overs). I didn't dare to open the terminals afraid of disturbing the current setup. As you can see in the images...head of some of the screws have rusted if I rotate them, they will break.

Guru's please suggest me what to do next. Should I continue with the same or should I go for new pair of speakers.

SAM any help on this

You can still open the screws I dont think they should break just be careful and do not apply too much pressure.

If the screws do not open dip the tip of the screwdriver in WD40 and put a drop of WD40 on the screw. Just enough to lubricate.

Once you rewire the system it is a good idea to use non-conductive paste over the screws so that they dont corrode so fast again.

I suggest you take the crossovers out, change the screws and wash the PCB with WD40 and a toothbrush and repack the whole thing.

Isn't the speaker's magnet casing rusted too? Won't that cause any problems?

Hi Guys,

I had 04 JBL components in my car and the crossovers for my front components were placed in the front door and the crossovers for the rear components were placed below the dashboard of the car. After 02 years when i was getting the wiring changed i noticed that only the crossovers placed in the front door were corroded wherein the ones placed under the dashboard were absolutely fine.

I suggest all crossovers to be placed inside the car and not in the doors for any setup.

But then, if i remember right, didnt the Audio gurus suggest that the wires from the crossover shouldnt be too long, that it should be in the close vicinity of the speaker.

Hi Spinner,

You are right so i guess the front crossovers can be placed under the dashboard and the rear crossovers in the trunk. Im sure that would be an option rather than having your expensive equipment in ruins.

I dont remember any of the gurus suggesting this. the distance electricity has tro travel from amp to woofer or amp to tweeter will reamain the same if the wires are longer at one end (woofer/tweeter to XO) and shorter at the other (amp to XO).
