That's what you need to get for that amp.

 

I would suggest looking into getting a different amp though, a mono or 2 channel amp would be better for that sub :)

Sorry yeah the black and red, have moved them over. Still nothing. I hate wiring

 

Dont know if it makes a difference what pre out it is in on the stereo itself?

 

What options do you have at the rear? Sub out or rear out is the one you want. You might need to enable the pre-out in the stereo settings.

Will I need that before it will work then? Will grab a picture of the back of the hu now. Have enabled the sub option on the options.

 

If you have enabled the sub option, you need to have it connected to the "Sub out" pre-out. Whether that's a sub out pre-out on its own or the rear output will be down to the headunit spec.

 

You don't need those before it will work bud, you only need those to have it wired like you initially did :)

Change the phase to "normal"

100hz is fine for the cut off.

 

I doubt that will fix it but I'm still going through it. I take it the other speakers are working fine? Could you let me know what settings are on the control knobs on the amp itself.

Yeah at this rate I may. Seems odd to me even though my knowledge on the subject is poor. Even is the knobs are all over the place would it not be normal to hear the sub doing something. Hate leaving jobs half done.

 

It's unusual but not impossible. My thinking is that if the headunit is filtering the audio to play only LP through the pre-out and your amp is set to filter the audio to only play HP then you'll be left with no sound.

 

The amp you are using is a 4 channel amp. It's likely that it was configured for door/car speakers rather than subwoofers so it's possible that it was set to hpf previously.

Don't worry about it bud, it's just hard to follow with the way you wanted to do it. I've now did a wiring diagram that I can follow in my head with ease.

 

A1 - R1

W1 - R3

W3 - A2

 

The above is what you need to have the voice coils in series. The 8 connections and the A's, W's and R's had my brain confuzzy :D

 

Edit:

 

That's how it's done :D
