First burp... HU @ 0 position on sub control. Matched best score ever with the Monster at any time (155.3) -- best I ever did at my shop on my meter was 155.1 dB, though. Now... HU at +3 position ! MY BEST SCORE EVER -- one OR two subs Man I am excited... 155.9 was my best before with two Nightshade 15s and four 3000s on an 18v system. This time... ONE NS v.2 15" and two SAZ-4500Ds on 12 volts !
