1994 Cadillac Deville Repair Question
1994 cadillac radio
The only quick diagnosis I can offer you, will isolate if it is a speaker. Swap the left door speaker with the right. If the left one still acts up, it is the tuner or amplifier. To determine which is possible, you need to know which sound system you have. If it is a base deville, the speakers are probably driven by the radio.
