Hello Collective, I have a question regarding the wiring of my stereo. I recently installed an after market Sony CD Head Unit, Boston Acoustic 4" speakers, Sub-Woofer and an Amplifier. Wired everything up and it sounded great for a month. The other day one of the speakers started buzzing! Pulled the speaker and exchanged it for a new one. New speaker also buzzed. Checked the connections at the amplifier and visually everything seemed fine. There are two coax cables that come from the head unit. Cable A (Left Front Amp In) and Cable B (Right Front Amp In). If I unplug Cable A, LF speaker stops working and RF speaker plays beautifully. If unplug Cable B, RF speaker plays and LF speaker plays and it buzzes. If I take Cable A and plug it into the RF Amp In, RF speaker plays beautifully. So I deduce that the signal reaching the Amp is OK....am I correct? The fact that both RF and LF play when only one signal is being sent to LF Amp In leads me to believe there is a bad ground? Am I close? I tried grounding the Amp body but nothing happened! What could cause this? I am a Financial Analyst, are there any electrical engineering types out there that could help me? If my reasoning is sound I'll just return the Amp and tell them about the ground leak. However, I don't want to be laughed out of Magnolia Hi-Fi when I bring in my Amp. Thanks in Advance of any Advice!
