I bought a new alpine deck and installed it... the power indicator eventually started blinking and the controls on it stopped working. I brought the car to a professional audio place and they said I burnt out the new HU!! I am now on my third HU!! I've burnt out two of them.. the audio place said my front speakers were running at 4 Ohms and my rears at 36.1 Ohms a piece! does anyone know why? Is there a factory amp in there? I have a 2003 with No Bose.. :helpsmilie: :xZ!o:

Did you run new wiring to the speakers? are you using the factory speakers?

Factory speakers and factory wires... could they be blown? Is there a factory amp in there?

Correct, the factory front speakers will run at 4 ohms and the rear run at 36 ohms. There is not factory amp on the non-bose stereo. However, these ohm ratings should not cause a problem. 36 ohms in the rear will just mean that channel will be under utilized and the amp in the headunit will have to work less. 4 ohms is pretty standard and most modern headunits, especially an Alpine, should be able to handle it.

It sounds as though you did the original install. Are you 100% certain that you wired everything right? Did you use a Metra wiring harness adaptor or did you simply snip-off the factory plugs and hardwire it yourself? Once the first one blew, did you have the professional redo your wiring? Have you checked it since?

Do me, this really sounds like a bad wiring job. If you don't wire in right, you could easily fry a headunit, or three.

I agree with what is said..sounds like a bad wiring job somewhere. Where are they testing the rear speakers and getting 36ohms? Sounds like they are testing the wires behind the radio. If BOTH left and right rears are testing at 36ohms, then i bet you have the speakers wired wrong (maybe grabbed the wrong wires behind the radio) If only one is reading 36ohms, then it may be blown.

Actually, the stock rear non-bose speakers are 36 ohms. Yea, I know, I was surprised myself. Nissan/Clarion did this so that you could set the fader at even and keep the rear speakers from screaming in your ear. I know, amazingly stupid, but true. It is even printed on the rear of the speaker.

I'm going to get a new harness.... my brother-in-law did the wiring, the audio place checked the wiring and commented several times on how well it was done. My brother-in-law probably did better than a professional job, soddered all the wires and even heat shrunk the wires together and then used twist ties to keep them tight together as well. He's building a jeep from the ground up and put the engine and a wiring from a an old chevy in there himself. Could just be a set of faulty wires though... going to get a new harness and try that out... I have another set of wires for the radio, I just need to go get a new harness... hopefully that will correct the problem... I feel stupid to keep going back to Best Buy with a fried HU, oh well.. Thanx for the advice and help guys!!!
