I've done car audio work in the past (not up with the current trends and integrating mobile tech and so on, but fine with installation/wiring and such so possibly able to help) and I think benji does or has and I have a feeling there are more than just us. |

ok so here is the deal. i recently ran new 1/0 gauge wire from a distribution block to a circuit breaker in my car because my battery is located in my trunk. ever since i put new wires in my speakers started acting up and cutting out. so i bought a new head unit and everything worked again. but after a day they all stopped working and only the sub plays sound. i tested all 4 speakers and they are reading .75 ohms. which im told is not enough. i can post pictures of my set up if needed.

What kind of vehicle. Some of them have pre-amps. Are you using the factory speakers and speaker wire? Need more info. The 1/0 wire, I am assuming, is just to run the amp? So I doubt that would affect the sound coming from the non amp/RCA source.

The pros will prob have a better answer, but I thought you couldn't really measure impedance with just a meter set to read resistance. I don't recall trying. I would usually try a speaker with a known good source.
What you describe reminds me of what happened when I had a pro shop install an alarm. I was 17 and had done my own stereo work and would have done the alarm, but my parents were giving me the alarm for Christmas and insisted that it was all taken care of for me. The pros put a screw through a speaker wire while working on it and that caused something very similar to what you describe. Speakers popping and cutting out. Prob not what's up for you, but you did mention that it happened after running a new cable so if you think that's at all possible when panels were worked with it could be worth a look.

i have a 91 honda civic and no i have all new wires ran for the rear and driver door but the passenger door is oem harness. and no the 1/0 gauge wire is for my battery. i have maybe 0 gauge for my amp. but my speakers have worked for years and all the sudden they all stop working at the same time? and i will pull one out of my car and see if it will work in my home stereo system

What sounds like happened is you blew your speakers, if in fact they are at .75 ohms. Are you testing them while they are still hooked to the amp? If so your not metering them properly and that's why the low reading.
One of two things happened it sounds like. Either you have a grounded out or shorted speaker wire somewhere causing your amp to shut down (or possibly blow..) or you blew all your speakers when you hooked em to the amp, which can happen. Sometimes people over do it on the first day and fry all four speakers haha. But I'd check the speaker leads w a meter again, make sure they are disconnected from the amp when you do (also don't touch the leads either).

Your speakers should meter at 4 ohms, or very close to it. Anything else, or an open reading, means bad voice coil. And that means bad speaker.

Took out all of my speakers and tested them on my home stereo. They all work. So what could it be?

Speakers good: tested check! Nothing new or complicated added: check!....could be the wires...maybe a small short etc...Crazy I had a short on my previous dirt bike...road it 20 30 miles until it went up in smoke...hahahhahaha so yea test them wires!

You could make a short finder with a circuit breaker fuse (add wire/2 spade connectors) and compass.

So your amp is a sub amp? Have you tried unplugging your RCA's from your deck and seeing if the problem goes away or not? If it does, you could have a bad amp ground. I would also check the power and ground wiring for your deck.
