need help no bass

[j_roude89]

Installed my tfe8k today running 6 d3100s gettin no bass. 3 pos and grounds ran from 3 seperate batts getting 14.5v from each set to amp with truck running and getting 1.2ohm subs r 4 fi q 15s d2 wired to 2ohm this has me stumped. Gonna get flack but yes as of right now have stock hu with loc wired in (it works fine had 2 of the 15s hooked up be4 with no issue period) i do not have grounds ran off batt bank yet which i kno i need. Any help would be appreciated fellas. Truck is a 99 tahoe

Check power at amp. Check grounds to. Then check remote wire for power

Make sure it's not on slave mode or something dumb like that

As stated gettin 14.5v at amp on each set of power/ground. Grounds off batts and r tight and yes the switch is on master

is it turning on? is it going into protect? check the impedance of the woofers. make sure you have hem all wired correctly. you have the rear batteries grounded to the frame/body?

Havent grounded batt bank yet i am goin too but with amp gettin power no problem didnt think it would be critical and yes iv checked ohm gettin 1.2 at amp so sub wiring is good

All my checks with the multimeter have been fine and i kno batts r good if im gettin 14.5 at the amp maybe it is bc of the grounds. Iv never did a multi batt bank this big be4 would those grounds from batt bank really make that much of a difference? I just put the amp in the test it basically and yes i kno batts need to be grounded

So you don't have the battery's grounded at all?

My grounds r ran from batt to amp figured if i was gettin a solid volt from there id be ok just to test. Im not done by any means just thought if i wasnt gettin enough ground the amp wouldnt work period. Im gonna run ground runs from the batt bank later today

If it is the reason i didnt think it would affect it that much. Iv been told i should be gettin something the way it is
