Can you add a subwoofer to the stock Hk system or will a full retro fit of other stuff be needed?

It's possible to connector speaker level from one of the rear H/K speaker coils to an amp. You'll still be subject to the processing inside the H/K amp, but more than one person has done it successfully.

Cool thanks... ill have to work on this.
If anyones got reccomendations of what to get Gimmie a holla!
Im gonna upgrade the componets as well then i should be set.

 

I'm doing this on friday. I have H/k speakers and i'll be putting in my new W3 w/ the t360 amp.w00t i can't wait!! lol

 

Took me about 10 minutes. Someone has a good diagram to use in connecting the converter to the h/k amp

 

I did this with a JL stealthbox and a Rockord Fosgate Punch 360.2 amplifer (older model, got it on ebay for $80). It has a high level (speaker) input and works fantastic. I used shankrabbit's diy, which also has a link to gbmini's site which has the h/k amp connector diagram.

Having high level inputs directly to the amp really simplifies the install, but you could easily include a converter. Using the diy instructions and the connector diagram, it was the easiest sub install I have done to any of my cars with an OEM radio. Props to shankrabbit and gbmini for posting these.

BTW, I tapped the high level input signals directly from the existing h/k amp output cables, which i got from the connector diagram. I didn't replace the stock speakers, so I wanted to avoid removing any additional panels.
