I had to borrow a Hartke 5500 head to power my Ampeg classic 410 but I saw the amp was rated for 8ohms and my cabinet is rated at 4 ohms. The amp has 2 speaker outputs labeled 8 ohms each, yet the amp has a sticker on the back with ratings for both 4 and 8 ohms. The cabinet has only 2, 1/4" jack inputs and an attenuator dial. Its a borrowed amp and I don't want to blow it up. Tried just plugging it straight into the cab and had the volume turned down. It gave a quiet distorted sound when I plucked a string. Can I rewire the cab, even though it has that attenuator dial on the back? Did a speaker wire in the cab come loose? Can I use 2 cables from the amp to the cabinet? I have a rough understanding of ohm loads but I'm very short on time and need this rig working "like" yesterday. Could anyone help out.
