Thread: Need help with a speaker/sub setup

you will need to check all the connections, it could be anything--there was just another thread where someone was having a similar problem with their amp

otherwise, try a different set of speakers connected directely to the headunit with known good wire.

check and make sure that the hu is getting good power and good ground(will need a mulitmeter), and that there is no frays or broken wires going into the radio.

Right now the sub/amp is not hooked up. I only have those 2 speakers and my stereo in my car. And i know the wiring is good cause i redid once i got the car. I think what the problem is that when i blast the volume too high the speakers are putting out more than the car can handle so it shuts them off with the stereo for safety. But i was wondering is it possible to hook up an amp or a power converter type thing to my speakers.

what year/make/model car is it?

i have never heard of any car or stereo that will turn off to prevent damage.

some radios have a volume limit setting, but no stereo will cut all power if it gets too loud.

Its a 1997 Chevrolet cavalier 2.2L. And it doesn't cut all power as far as i know. I believe it just shuts off my stereo. And i know it cant be some limit because i can play some songs at 30 volume and then some i can barely play at 20 volume because the base is so loud it just shuts it off.

get yourself a good multimeter. pull out the stereo and unplug the stereo harness. test the resistance of the speaker leads at the harness. should be 4ish ohms for each then test each speaker wire to ground, should read nothing. if it reads outside of these specs is why its going into protection mode.

also check your ground, make sure you have a good solid ground for the stereo.

Oh snap i guess the ground might be the problem. My cousin hooked up the stereo so ill have to double check that. Cause the stereo came with a harness that i had to connect to an adapter that connected to the stock radio connector. The adapter came with a black wire so my cousin hooked up the black wire from the harness to the blackwire from the adapter.

Should the ground from the harness be connected to the adapter or somewhere on my car?

usually the adapter but if that ground is bad (this is where said multimeter will come in handy), then just run a new one. i cant stress enough how much that meter will help you. start with a cheap auto-ranging one ($30 craftsman works great).

Yea i bought a 15 range digital one from radioshack for 20$. Can you explain to me in more detail as to what i should be touching and with which lead cause im new to the meter.
