so you had the + and - turn around on your amp for power right? or you just had constant power to your amp?

ok well i just got back and i had the rem hooked up to the power antenna lead. so i got that wired and now the amp powers on. but now the sub isn't wanging anywhere near what it should i turn the gains up all the way briefly and it's decent but not like it should be. i have the gain switch set to gain (other options are master, copy for strapping amps).

then, i have the gain turned up about halfway. (nothing audible til about halfway up). the low pass filter is set to full (other options are 12, 24) and i have the frequency set kinda low so as to not damage anything til i get it figured out.

the hpf is set to off (other than on) and the setting is all the way down.
the intelli q is set to 0 (bass boost basically).
the phase switch is set to 0 (other than 180).

my wiring is 4 gauge from battery to distro block with 200amp breaker.
from fused distro (2 150A anl fuses), i have 2 runs of 4 gauge to the amps power and ground terminals. so all 4 gauge wiring throughout.

the sub itself has 8 gauge wires to each vc. then i believe 14 or 16 gauge wire to the amp's terminals (speaker wire). rem turn-on is very small wire (knukonceptz rca wiring kit w/rem wire).

i had the eq set to flat and loud turned off on the headunit and i had it up to about volume 26 and this sub is barely moving (wired to 3ohms off an orion 2500d, so ~1400rms to the sub and recommended is ~1000rms to 13w7). any reason why this sub isn't wanging like it should?

*edit* also, everytime i touch the headunit, i can hear some kind of low poppy-ish sound from the sub like the headunit is interfering with the sub. it does it when i press the buttons to change stations and turn up the volume. but i have a remote i can use for the hu..

i had constant power. but i fixed that. i had the amp wired to the power antenna lead instead of the amp turn-on lead.

what kind of deck do you have? and make sure your rcas are good.

read the long ass post i just wrote please and see if you can help me. it's a kenwood mp225 i belive. (got it 2-3 years ago. just a temp til i can get a new 06 pioneer deck). the rcas should be good cuz they were brand new never used.

Have you checked all of your settings on your hu? The preamp you are using could possibly be either really low, or not working.

it sounds like its not getting a signal or barely any signal. how many sets of rcas does the deck have? if it has more than one try a differnt one.

it's an older low-end kenwood. the eq and all that is set to zero. there's no subwoofer setting or anythign like that. just your basic treble, mid, bass, fade, side, and loud settings. the pre-outs were good as i had this deck in my truck using my fosgate amp and sub and it was fine. i blew 2 subs off of it. so idk what it could be. it has one set of pre-outs. my pioneer had 3 sets. wish i hadn't traded it for something i'm not using. gr.

Is there a switch on that amp for the gain? Some amps have a switch for higher voltage input and one that brings it for lower voltage input. I'm pretty sure that hu has a low preout voltage (probably 1.7 volts or so) and your range could be something like 8 volts to 4 volts (like JL audio amps, when you flip the switch, the range is 6 volts to 300mv). But that is if you can switch it.

there's 3 total settings for the gain: copy, gain, master. that's it. then you have the gain setting dial. the lpf has 3 settings:full, 12, 24. then has the frequency adjustment. no switch unless there's jumpers internally on the amp's board.
