Hifonics bx1505d

just hooked it up today, some reason you have to turn the volume on the headunit like really high and the gains quite high to get any movement out of the sub, i've chekced everything over and over and over again and i can't figure out the problem. i have my mag d2 wired to 1 ohm parallel.....

I had the hifonics bx1000d before, worked fine for over 2.5 years...it's like i have it wired wrong and it's only seeing like a 4ohm load, or something. but i'm almost positive it's right. Wires out of terminal positive to positive negative to negative into one terminal then other wires coming out of that same terminal to the other side negative to negative positive to positive

I'm now 100% positive it's wired right, wired it exatly like the tutorial on Jlaudio.com. This is ****in weird, the amp doesn't turn on protoect, it comes on right away, you just have to like turn everything up for the sub to even flex

You went from a BX1000d to a BX1505d? Why?

There is not much of a power difference there.

What tone did you use to set your gain?

We used the DMM, ended up with the gains at about 5/8 the way up, but we turned it a little bit higher than that where we got the most output
