[QUOTE="Jimi77, post: 8840871, member: 673702"] Turn the subwoofer output to max. Turn the gain down on the amp to where you're comfortable the the amp isn't clipping. Play a 0db sine wave at say 50-60hz and turn the volume up on the radio until you here the pitch/tone of the sine wave change - it'll get higher, it may take on a more mechanical or harsh sound. That's clipping. Now you've identified where you can hear clipping from the HU pre-amps. Keep your volume 2,3 db below where you can hear clipping and you should be good. You should probably repeat the process a few times so your ears can become accustomed to what a clipped sine wave sounds like. There may be comparison tracks floating around on the internet to help your train your ears. [/QUOTE]
