sorry for the question, I am in the learning process.
I am using a jl audio xd600/6 to power a to hifi system. I would like to add a jl audio xd400/4 to power only the subwoofer. By the way I am using technic harness. How can I connect the jl audio xd400/4 to the system?

Thanks

I don't know anything about these amps or the specifics of Technic's harness, but I did see the xd400/4 has a preamp output. Feed the xd400 with full range preamp input, low pass the speaker outputs for the sub(s), high pass the preamp output from xd400/4 at same xover freq as sub lp (if possible), feed the now high passed preamp output of the xd400/4 to the preamp input on 600/6 that you want to use for underseat woofers, low pass at freq you cross the underseats with the doors, feed rest of 600/6 same as it is now.

Or you can get a 900/5 amp. I did this on my previous set up just because to power two amps would require tapping into them both. I had a W7 10" and it was more than enough power. Vocal was clear too.

How did you have this amp wired up? Did you use 2 channels for both the doors and subs under the seat, and 2 channels for the rears? Thanks
