I had something similar happen in a "winter beater" I put a system in, expecting to use the vehicle over one winter...in the end, I drove the car 2 1/2 years. I sold it for parts, and when stripping the system out found my speaker wires looking similar but worse.

I used Monster home theatre speaker wire (that looked similar to what is in your photos), what I had on-hand when doing the install off a bulk roll. Inside the car, after 2 1/2 years of touching sealant, plastic trim, upholstery etc. and undergoing the heat cycles of a closed up vehicle parked in the sun, the wire insulation was falling apart, had partially dissolved to glue like consistency. The melted insulation had stained carpet, melted onto the underside of some plastic trim pieces and had bare copper showing in a few places where I disturbed it. The wire insulation smelled strongly like vinyl when installing it, but did not stand up to use in a vehicle and melted into oblivion after touching vehicle trim and carpet over the 2 1/2 years. Mine made a bigger mess than yours.

In spite of still having a partial roll and remnants of that speaker wire kicking around, I haven't used it in a car install since. I have never experienced that with automotive speaker wire, the worst being finding the ends falling off of some Scosche RCA cables I used in my old Jeep. The boots on the RCA barrels were made of similar material to the Monster speaker wire insulation and had turned to gum after a few years. I discovered this when troubleshooting some channels cutting out, and had to replace all of the Scosche RCA runs with some Stinger cables.

Was that home speaker cable you used?

Probably similar composition in the wire insulation.

As well you should. 2007's Alpine line up of HU's was pretty good .

Yours held up better than mine for longer...garage kept? I'd still change out that speaker wire though .

My POS was parked out in the elements, so the home audio wire decomposed faster than it might of in a more temperate environment.

FWIW, I've used lots of the Scosche speaker wire (available on spools @ Walmart) in installs and never had any issues with it...fairly cheap, readily available and decent enough for the task at hand.

^^ might be worth a try if you don't need cash & carry
