Converting Monsoon stereo to Alpine

Repair cost would exceed replacement cost. Try disconnecting all the speakers and see if it works then. Try reconnecting each speaker by itself and see if that causes the problem. Most grand am have the monsoon sound syatem...even if they aren't labeled as such. Pull the carpet in the trunk on the left (drivers) side wheel well. The monsoon amp is located over the wheel if you have a monsoon system. If you have to remove the amp then you must change the speakers out or rewire them as the monsoon system uses bi amp speakers. Most of the ga forums have extensive write ups on this system.

Unless the face of the stereo says MONSOON there is no separate amplifier. On a Non-Monsoon Delco system all four amplifiers are built into the stereo, Left front, Right front, Left rear, and Right rear. Monsoon systems do have a separate amplifier which basically boosts the output of the four regular amps in the radio. I can't imagine all four of those amplifier output chips going out at the exact same time. I would pull the stereo and check if all plugs are seated properly. If those were all securely plugged in I would (myself) inspect the inside of the unit for the cause of failure. For example all four amp chips pull power from a common point and if one chip had a severe enough short in it, this may have caused the power feed trace on a circuit board to overload (too much current going through it) and created an open which killed power to all four of them. Any good electronics repair shop worth their salt should be able to repair it if you can locate one willing to try. It may only need a circuit board trace repair and one amp chip replaced.

Have to get a factory code from GM

Without experience I advise u you do it once & do it right. It will end up costing u more in the long run. Ive seen it many times. Good luck Shop around, even go online, Best buy isn't the only installation shop. they're top $ anyway

Sorry a 2004 beetle doesn't have a monsoon radio but you can buy one and install it inside the car.

it will have the logo on the radio faceplate if it has the system

I had the same problem with mine and my 2004 Chevy Silverado. Gm is making the cars so that have to buy the quick connect harness for it to work. All the chimes, idiot lights, electric read out is all through the radio harness, so you can not cut and splice any more. These harnesses are expensive too. Best buy is price at $120.00 for the Grand AM. My truck was $115.00. Its F****king rediculous!!!

Just need to buy an transmitter can buy one alost at any store.
