Pioneer DEH-6400BT, cant figure out where HPF is

Pioneer DEH-6400BT (deh6400bt) Car Stereo CD/MP3 Receiver with

Bought and installed, and I cant seem to figure out where the HPF is....I even read the manual. I find the LPF for the subwoofer, but I see nothing about a HPF, and the product description clearly states otherwise:

"Internal Low-Pass Filter (LPF) and High-Pass Filter (HPF) allow advanced tuning with aftermarket amplifiers"

Im going to run my front amped, and rear off the HU, and I know I would be able to set the HPF for the fronts on the amp, but I dont want my rears playing full range, especially since they will be cheap OEM crap.

Any thoughts?

Well that *****. I guess the only way to lower bass is under the auto tune fuction. That reduces bass on all speakers though. Not happy about that. Likely will throw it back on ebay and go with the 6500bt
