when i was running my btl 15 off this same elec. i never got voltage issues this low(12.8 and under)... i just installed 2 ns 12s at 2 ohms strapped and i am getting the issue, gain at a quarter and volume at half... i have a ohio gen 180/225 ho alt sittin here and will be dropping it in... i also did NOT do a big 3 yet, but the factory wire is 2 runs of 8, will be upgrading to all 0guage soon. with all this accomplished should my voltage maintain a good number.

i was also told that since i am running the power between 2 subs now that it maybe drawing more... is that true?

what amp?

what impedance was the btl?

You are using more power now.

man there is something else wrong. check you fuses. i have a 90 alt and kinetik 800 & 2400 for my SD 3K and my voltage doesn't drop below 12.4 at full volume. it did at first but after i checked it out. I found out i had a bad fuse. It wasn't blown just no good. so i was running off the rear battery only. so check your voltage before each fuse.

will check the fuses in a few minutes... the btl was d1 and the 2 ns's i am running is d2s.

should i start to smell the subs already, i just put em in tuesday and i was playing em last night and smelt something funny, no smoke though, is this normal?

Yah - you will smell subs on high power. It's normal as long as you don't smell it incredibly strong.
