Kicker Zx1500.1 Puttin Out 1100 Rms? Wtf Help Please

[bumpincruiser]

ok so i went out to set my gain propely in my car and ran into a problem. for starters i have a hdc312 being ran off a kicker zx1500.1 at 2 ohms, kicker 1/0 from batt to amp, 1/0 ground, and an exide orbital d34 batt. also next week im doing the big three. so i think that my electrical is not spectacular, but its enough to run my amp.

i wanted to throw about 1500 rms to my AQ so that is what i was going to set my amp to. according to the table on this page i was supposed to set my amp voltage at 54.77..

so i did everything right i used a 50 hz tone, disconnected speaker terminals, turned off my other speakers so i didnt have to listen to it, set everything to 0, hpf off, and started playing the track.

i also set all gains on the amp to 0.

i had my dmm plugged into the terminals and proceeded to try and set it at 54.77 but on max gain in was like 46.xx? wtf so that means im getting like 1100 rms? am i doing something totally wrong here or is my amp messed up.

btw i checked my ground and its good and my batt is idling in the 14s.

help please!

Not enough input. What's the preout voltage on your headunit?

2v

but another guy is getting his 54.77 on the same amp with gain at 40% using a LOC and thats only 1.5v

most LOCS have gain on them.

i meant gain is set 40% on the amp

Some HU need to have the subwoofer option turned on to get bass output.

yup i think that was the problem... sub setting was at 0 and i guess on alpine h/u the subwoofer setting needs to be all the way up.

i guess the h/u only puts out like .3 v with sub setting at 0 and the full 2 at 15

so im going to try again tomorrow

Yea, thats problably the problem. It is impossible to get much output on mine with it set at 0
