[QUOTE="keep_hope_alive, post: 8250789, member: 576029"] for SQ setups I use a 0dB tone to ensure the amplifier is far from clipping and audible distortion for all volume ranges. for SPL setups I use a 0dB tone to determine the exact volume setting and sub level setting to achieve the highest amplitude signal that is still clean. Then we use a 0dB tone and replicate the volume level and settings during runs. as long as you understand what you're doing, 0dB tones are just fine. clipping is audible in subwoofer systems if you build the system correctly. if you cannot hear clipping over rattles, then the install is poor. trunk subs have always been more susceptible because it is harder to hear clipping through the seats - that is where careful gain adjustment and an understanding of signal levels is important.
