Im looking for a gain **** i can keep up by me to control the bass and the one i got doesnt do anything so i returned it. Gain **** as in no bass to full bass. Can anyone give me some help and help me find a universal one or the one that can go with it.

Yep, that's what it does. It goes inline with your RCAs, and basically allows you to attenuate the signal from the HU. I've had to buy them in the past for Alpine amp installs.

Okay cool just wondering because on one of the reviews for it they said it only went from 0db to -12db and there saying it doesnt hit hard unless its on rap? I want mine to be able to hit hard on anything i listen to

And also it the wiring going to be long enough because my amps in the back with my subs

You'll need a second pair of short RCAs to go from the HU to the input on the gain control, then hook your existing RCAs to the gain's output.

So i basically need a small pair of wires to go to the head unit, and it connects from the head unit, to the gain ****, to the amplifier?

Okay gotcha and where do i connect them to the HU and the amp? I looked at the amp and the only place i would think it can go is in a place that says pre-outs. It has the same ends as those wires so idk how they would go in?

the 0-12 is how loud it gets. it is easier to use that to adjust the volume level of the amp than using the headunit as the HU goes in increments and the bass **** you can adjust easier. i use mine since different tracks have different bass and different frequency's. mine usually only goes 1/2 way unless its for db drag or other comps. and anything works; you just have to find the right track. hell country quite often has just as much if not more bass than rap/hiphop (and i hate country lol). but techno is good and yes rock/metal does sound good and hit especially when using the double-kick pedal.

Okay thanks!
And i looked for RCAs and i found some that look like they would go into the pre-outs on the amp but is that where they go?
And where do they go on the HU

there is one that connects from the head unit to the amp remote; then from that there should be a set of "out" ones from the amp remote to the amp itself.

on the headunit you should have an "output" set of red/white (left right) and the amp should be the inputs
