My friend bought a 93 Jeep Grand Cherokee.

  • 150,000 MILES
My friend bought a 93 jeep grand cherokee limited with the premium sound package and amplifier underneath the back seat. After he got the jeep home, he was trying to play around with the aftermarket head unit, and discovered that the unit had power to it, but no sound came out of the speakers. He lifted up the back seat and discovered 2 amplifiers and that the car had been wired for subwoofers. The speaker amplifier had no power to it, and somehow he got sound to come out of the speakers for about 10 seconds and the subwoofer amplifier started to smoke. What is the cause of all of this?

Someone removed the really high-quality original system to put one in that would destroy their hearing. I refuse to work on ridiculous sound blasters, and I don't have the money to spend on expensive aftermarket radio service manuals that I might only use once. I stick with original equipment, and Chrysler products are my specialty. If you want to put the system back the way it was, I can help with that.

In particular. '93 - '95 Jeeps use different mounting ears for their radios. The Infinity radios came with a cassette player or a cd player built in. As I recall, they never had both. Some people cut the mounting ears off to install the cd / cassette combo radios which were made by Mitsubishi and are REAL high quality. The cd-only radios were built by Alpine.

Any Chrysler radio will run speakers directly, AND they will work with a factory amp. With GM and Ford radios, if they use an amp, they need an amp. Chrysler amps do not increase volume or power. They only change the tone for the shape of the vehicle. An Infinity model puts out much less bass, then it is made up in the amp. If you use a non-Infinity radio, it is exactly the same inside except you'll have too much bass. Likewise, if you use an Infinity radio without the amp, you won't have very much bass.
Was this
