That has an impact on the amps ability to drive the sub channel. Also, as bigaudiofanat has stated, you'd have to adjust the gain on the amp and head unit to full tilt just to see that amount of power. At that point, the sound would more than likely distort and you'd probably end up damaging your speakers. |
OK, where did you come up with that hypothesis? The HD900 has its own dedicated power supply for the sub channel that is isolated from the other main channels. Also the amp gain is NOT a volume knob and has no correlation to power output. the gain is simply for balancing your line level from your source "headunit" to the amplifier. Any other use of the amplifier gain will only introduce distortion into your system which is why I think the HD900 amp didnt work well for you.
Rest assured that JL Audio amp was designed to run 900 watts rms within grueling tolerances at a bare minimum otherwise they would not put thier reputation on the line for thier flag ship car audio amplifier. If not, there would be a classaction lawsuit against them.
