radio issues
Hello,
I have an aftermarket radio in my 97 250, and when i turn up the volume, the speakers cut out. if i turn the volume back down, the music will come back on eventually but it is getting pretty annoying. I have tried another head unit, all my speakers are aftermarket, and i've even tried re-wiring the head unit/plug adapters, and the problem persists. Am i shorting out somewhere, or what the heck is going on? any advice is appreciated.

It sounds like a wiring problem to me. I am not sure if you have used your own wiring run to the power source other then the original harness, or is you have used an aftermarket harness connector. The aftermarket harness connector is the best way to go.
It could be something as simple as grounding, but it could be that if you wired into a pre-exsisting wire that was not part of the radio harness, that you pull too much a load for that circuit when you crank it up.

Did you wire up the speakers or did somebody else. The impedance of the speakers must match the existing radio/amplifier and per manufacturing instructions. You can't just connect it in any desired manner. From your description it sounds like the radio/amp is protecting itself from over heating.

yes i wired the speakers and the radio myself. i used an aftermarket harness for the radio itself, and i just matched all the colors on the wires and hooked it up.
As far as the speakers go, i had the suspicion that might be the case, and i replaced the front 2 with the stock speakers to see what happens, and it still has the same symptoms. i would think that the front 2 speakers would keep playing and the rear 2 aftermarket ones would shut down? I am no audio professional, but the aftermarket speakers are pioneer 3-way speakers. maybe the stock amp isn't powerful enough to handle the load and overheats in turn? I'm frustrated and lost here

Not sure , what head unit you have, but if it has a build in amplifier, it might not get enough power through the factory wiring.the radio will draw too much power and the voltage collapses, causing the radio to kick off. Providing you are sure, that you did not mix up any wiring , nor reverse polarity on your speakers, you can try running a single wire straight from the battery to the radio, as well as run a single ground to the chassis. Just make sure, it is of large enough size. If this fixes the problem, run a permanent new supply to the radio, but make sure you fuse it correctly at the battery.

anything is possible. One thing I've leared it not to rule anything out. But yeah what you say is pry more likley. Strange its only when you crank it. What kind of head unit are you running? Does it happen in the same mode (CD, AUX, TUNER) or not, just trying to get some thought going, sometimes one thing will lead you to another, never know.
