I just put in my HDC315 dual 1 ohm. wired at .5 ohm to a lanzar opti2000d. I set my gain with a 50hz 0db tone. with the speakers hooked up.. i turned my gain on the amp until the voltage (AC) was 28 volts thats roughly 1600 watts rms. On my headunit everything was down except i had the bass knob full. Then when i went to play music... it just wasn't loud at all. I then threw on my LOUD setting. and it started to sound like i thought it would.. but i knew obviously this wasn't right because voltage would be off now... Anyways so i went home to trouble shoot some more.. and with my trunk open i played a song. and the subwoofer was like bottoming out so i turned it down immediately. Anyone want to guide me through the setup of my amplifier and woofer? thanks
