 ZX1500.1 gains question

i just hooked up my zx1500.1 for the first time. to 4 12" alpine type R's(swr-1242d) at 2 ohms.   and i put on a test cd at 50.40hz and started trying to set the gains.i put the HU at 3/4 and i eventualy turned the gain all the way up and i could hear any distortion.even with music. i have the subsonic filter on. and i turned the bass boost up and didnt hear anything till about half way. is that normal.does anyone else have a zx1500,whats your gains set at,how do i check my gains useing my DMM.thanks for any help.

First ; make sure the test tones have been recorded at 0db not -3db

Rockford  Fosgate  has a really good write -up on setting amp gains:

I hope this helps.
