front speakers not working...wtf?

[Sulleigh 10+ year member]

if you have other speakers you should test them on the front speaker wire.if they work then it's something with the speaker........

The back speaker wires are working in both the front and rear inputs on the amp so it shouldn't be the amp. Maybe it is the speakers but they look fine and why would both stop working randomly?

Anybody else?

As you stated, you aren't even sure they were ever working. Maybe you don't have them wired correctly or they are shorting themselves out. How did you wire the front speakers to your amp?

I honestly have no idea, I had everything professionally installed and the place that did it has since gone out of business(or not necessarily out but aren't doing car audio anymore supposedly).

You'll need to find out. Sounds as if they screwed up. I know the first time I went to a shop for car installation they spliced into my OEM rear wiring and ran it to my front speakers. Cheap bastards //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Since the amp appears to be working you're probably looking at taking your doors and threshold panels off to see how it is wired and possibly have to do a new run of wire.

I took it to a audio tech at a place in town and he glanced at it. He thinks it may just be the wire coming from the front speakers to the amp. Would a dmm be able to test the wire?

To test to see if the wire at the amp is the wire at your door, do a continuity test from your DMM. Disconnect the wire on both ends. You'll place one prong of the DMM on the neg at your amp and then the other prong on the neg at your speaker (you may have to take a spare piece of wire and connect it to one of the prongs so the DMM can reach both ends of the wire). If the test is true, its the same wire. Try the same test on the pos of the wire and do this for both speaker wire runs. This can help you to make sure it's the same wire and they aren't cut somewhere along the line.

If all tests are true, then with the amp playing a 1KHz test tone (decently high volume, 2/3rd at least) place a DMM at the speaker connectors at the amp, take the voltage reading and then with the tone still playing place the DMM on the speaker wire at the door. If the voltage isn't the same this may indicate a wire that is too small or it is damaged and shorting out. FYI, you can disconnect the neg wire from your rear speakers so they aren't blaring in your ear while you do the test. The sub amp doesn't need to be disconnected because it doesn't play 1Khz.
