good prices all around

just received my pioneer gm d9601 amp, service and speed were great, just unfortunately slow postage even through express due to flooding in my region. overall though i'm happy with the product and the great price i got it at, the only negative i have is about the amp itself came with a remote bass knob which the amp needs connected or it barely puts out a signal without it however when connected the knob makes no difference when turned from min to max, not sure if it's a product fault or not
