Hey guys I have been up all night wiring my sub in... d2 SPL built to handle 2000 daily from my bxi at 1 ohm... Problem It wires down find and getting reads like it should but it's not moving to the point you can't hear it at all... My amp reads 9 ohms when turned on by it's self and with the sub connected as do the box terminals when playing... What am I Doing wrong?!?!

What do you mean your amp reads 9 ohms? That doesn't make any sense.

at the wire terminals it reads 9 ohms with my sub connected as does the terminals on the box... But when I disconnect the sub from the amp the ones on the box read 1 ohm just like they should

Yeah and my discus reads 1.8 with the sub connected. dont measure your impedance at the amp.

make sure all your wire connections are good and make sure that you dont have any filters or anything set on the amp.

Well I wouldn't put much weight into that, I mean when it's connected to the amplifier you have a lot of internal circuitry that could easily be skewing your reading. It doesn't really matter what it reads once it's hooked up if you know the static load is 1 ohm. My guess would be your fault lies elsewhere. How did you set your gains? Even if your not a fan of the DMM method it would be worth the effort because you'll be measuring the output voltage of your amplifier. This will tell us if your amp is sending the correct level signal.

I have 4 volt pre outs and it's cranked eighths bass boost all the way up and it still doesn't do much so something isn't right lol

It sounds like the voice coils are wired out of phase to me.

Nope checked... Many times

Hooked it to my buddies punch 300 at 4 ohms and it pounds just as hard as it does on my amp at 1 ohm

Your amp blows? Have you hooked the amp up to anything else to try the amp out?

It was running my DD at 2 ohms and half gain and that thing was loud...
