[QUOTE="my2006c6, post: 8909600, member: 661724"] I just finished putting in the Bass Knob... And redid the gain setting on amp , with the Bass knob just below halfway point and my volume on head unit @ 29 instead of 28 . And just calculated the spec by 2 X 800 ( 2 ohm load and mono amp spec @ 2 ohms.) , and then Square root which shows 40 A.C. .. I tried one of those 40 dollar scopes and it worked only have the time so i cant trust it, but it seem there was no clip signal coming out of H.U. @ 29 from what it showed. And then used a 0db 40hz tone to set A.C. voltage at mono amp speaker terminal. Also i set the Subsonic on amp @ 30. I tried it out on a song that has a very low bass kick, and i turned up the knob and no clipped signal showed up on knob. I was thinking the knob raised the gain, but you state it raises the signal going into amp from head unit. ( I didnt know this) ... My other Amp that powers my 6.5 and tweeters is a GT Trading ,Twister F4-650 which i had shipped to me from Italy. Looks alot like the Old Boston GT-42 (great amp in their day, and still have mine) but this has more tuning controls. And specs are [LIST] [*]Power @ 4Ω 14.4v 0.1% THD: 4 x 170 w [*]Power @ 2Ω 14.4v 0.1% THD: 4 x 260 w [*]Power @ 4Ω 14.4v 1% THD: 2 x 520 w Bridge.
