Hi all, owner of a '99 Ranger 3.0 w 89k miles. About 5 years ago, I changed the spark plugs and wires in it, Autolite plugs and Bosch Mag-core (steel-core) spark plug wires. I've been a believer in solid-core wires since the 80's- every car I've tried them on runs better with them than with the stock graphite wires- better tip-in acceleration, better highway response and power. So I put them on the Ranger, with a new K&N air filter, and it ran better, peppy, almost if that can be said about the 3.0.

So fast-forward to now. All the stereo stuff is stock Ford, until now.
I put a Rockford Fosgate P3D4 12" sub in it, closed box 1.25 cu ft, with a Boss AR4000D amp (I know it's overrated, but DerekW {BigDWiz on youtube} dynos it at 969 watts RMS@ 2 ohms.) I upgraded the stock 90-amp alternator for a new 130-amp unit. Somewhere, I can't remember, in the last couple of weeks, I read that solid core wires are a no-no for computer-controlled cars and trucks, that it can fry the on-board computer. I also read, if I recall correctly it was in a car audio forum, that boosting the amperage of the alternator and using metal-core wires on a computer-controlled car, is another big no-no.

Does anyone have experience running solid-core wires with a high-powered audio system on a computer-controlled vehicle?

Has anyone here used the solid-core wires with the 130-amp unit? Like I wrote, I ran them for 5 years with no problem, and I'd like to keep using them if possible, but not at the expense of a new computer control unit. {I have temporarily replaced them with a set of stock Autolite wires- the difference in pep is subtle but noticeable}
