Hk sub wiring

Could someone explain where the signal for the hk 6x9 subs comes from.

I've looked at wiring diagrams and there is no "dedicated sub" line. I'm assuming the rear headunit line of the oem harness drives it.

Does the speaker output come from the rear speakers too?

I definitely used that wiring diagram to wore my current set up. Are th hk subs considered part of rear woofers?

If I connect an aftermarket amp to the subs, should connect the new wires from amp before or after the hk amp?

also it appears there is only a positive and negative wire for the subs, but there are 2 subs. I'm assuming both outputs come from the hk amp, is this correct?

Connect your aftermarket sub amplifier to the sub line signal wires after they leave main HK amp connector, before they connect to HK sub amplifier.

" Also it appears there is only a positive and negative wire for the subs, but there are 2 subs. I'm assuming both outputs come from the hk amp, is this correct?"
Yes. The one subwoofer amplifier powers both sub speakers.

Just a quick question, i found this thread https://www.e46fanatics.com/forum/sho...d.php?t=568846

and the one wiring diagram with the numbers shows there is a positive and negative on the input to the sub amp. Are these the wires that i tap. If i tap before the sub amp, i'm assuming that the signal from the amplifier will be divided into two signals for each wire (could you please confirm)?

So essentially i need only one channel on my amplifier to drive both subs because the hk sub amplifier which will receive the signal from my aftermarker amplifier will split the signal into 2 thus driving the hk subs (does this sound right)?

Also if i do this, i will not have to touch the 2 green and 2 grey wires going to each hk sub?

Thanks

Did you tap from the signal input wires going from the main amp harness into the sub amp connector?
Or did you tap from the sub amp wires going to the speakers?

If the former then something is wrong upstream from the subwoofer. Has there been any work done to the OEM audio setup? Headunit, wiring, HK amp?

If the latter then there are the above issues plus the issue of the HK sub amp's operation plus level/impedance issues.

(The above assumes your new taps are correctly done.)

I tapped the signal input wire going into the hk sub amp coming from the stock harness.

I actually removed the stock hk amp and replaced it with and aftermarket amp. For this installation I tapped the front and rear head unit signal wires from the stock harness so that it would provide 4 channels. Then I hooked up the speakers by again tapping the stock harness speaker wires.

When I tried to hook up the sub. I tapped the +/- wires going into the hk sub amp in the thread that I linked and connected it to channel 3 (rear head unit input signal).

When I did this I couldn't hear any sound from the sub.

Hope my description is clear. Thank you so much for the help.

I think I might know what the problem is. I did not attach a 12v power line, a ground, nor a remote wire, lol. For some reason i thought the speaker wire would just send power to the amp lol (it was cold outside). I will be doing that soon.

For the 12V, can i tap the stock harness. I've heard people getting power from the battery, but i'm not sure what type of wire to use for this installation.
