[QUOTE="keep_hope_alive, post: 8677536, member: 576029"] Nice equipment. When using a DMM, using a 50Hz tone is more accurate as most meters are calibrated for 50Hz-60Hz (typical AC voltages). Verify if 30Hz is out of the range of the meter, or maybe the head unit has a lower output at 30Hz. Note that any EQ boost will invalidate your gain process. Amp mounting tips: don't mount the amp on the box because 1. vibration takes its toll on the amp, 2. it makes it easier to steal the entire package, 2. the amp is visible increasing possible theft, and 4. if the box moves the amp wires are less flexible and can pull out. I assume you've securely bolted the box to the floor. [/QUOTE]
