Hi 👋 , I'm selling this amp for my neighbor , he said it did work when he took it out of his car many moons ago . I tried to hook it up to a radio and a power pack I have but I couldn't get any real volume out of it . The light comes on and I hear music and the volume knob works but the output is " REALLY LOW " ???? Maby I'm hooking it up incorrectly 🤷‍♂️ but 👉 “ PLEASE " 👈 buy it with the assumption that it's broken and needs repair . There's no mounting brackets . Again please consider this amp 👉 BROKEN FOR PARTS OR REPAIR . 👈 Thanks .
