I need some help. I have an older Kenwood deck and an Alpine M450 amp powering a single alpine 10" Type E Sub. When I crank the sound up my amp goes into same mode. I have literally replaced all the wiring (power, ground, and speaker wires) and tested the system with a differant sub, differant deck, and new Alpine amp. All duplicate the same problem with the Alpine amp. However, when I put my buddy's Rockford amp into my system, the sound does not cut out. And when I put my Alpine amp into his system with an Alpine deck it also does not cut out. I read that my paticular Kenwood deck puts out 4.5 volts but my amp only takes up to 4 volts.
1) Could there be a compatability issue with my choice of amps? Has anyone ever heard of this?
2) Any cheaper suggestions other than replace the amp or deck? Money is tight.
