Hi. I lost audio on my Dodge OEM tape deck except for left rear speaker. Bought a used Dodge OEM cd radio deck and hooked up to the OEM harness. Stilll no sound. I have purchased a Pioneer cd/radio with install kit. Using OEM wiring diagram, I made up a patch cable to install on the OEM wiring harness. Turned on the Pioneer CD/Radio and still no sound. I expect that the speaker amps are not working now. What is the best way to check each speaker amp to see if it is working. If the amps are in fact blown, what is the best way to cut out the amps and use the basic speakers with their integrated tweeters? Also, is there any other amp used in combination with the infinity speaker mounted amps on the RamVan 3500. If so where should I look for it?
Any assistance is appreciated.
