I had an issue with starting my Tahoe this morning. I put it on a trickle charger, and after ten minutes started it. I went to reset my stations and adjusting the bass, mid, and treble and noticed the low pass filter, and subwoofer settings are now gone off the menu. The Highpass filter was still on the menu. My Subs still work, my head unit still operates normally except for it's missing theses to options. Any ideas?
I had the same problem and I just worked it out. Its because your pre-out is not switched to 'subwoofer'. It will be on 'rear' instead. Go into the menu when its in standby and change the SWPRE option to subwoofer and then your subwoofer options will be back in the menu !

Yes on most alpine units this feature is available but the sub woofer has to be conected to the sub woofer input and if it's setup like this you can go to your audio menu on your alpine unit and turn it up or down I hope this helps.
I manage to slove to my DPX-U5120 Subwoofer level adjustment. In STANDBY mode, Press the Main Volume button and turn to Setting, turn until you find the SW Preout, Swith to normal mode, its won't work if u switch to REAR
Go back to CD/USB Mode, Then Press the Main Volume and find Audio Adjustment and now u can find the Subwoofer Level , Sub Phrase and Sub LPF adjustment.. Um Glad i found this and Happy Setting
The DXZ375 has two sets of RCA outputs (1 red plug, 1 white plug) located on the back of the unit. The set with the white main wire is for a front amplifier, and the one with the black main wire is the rear. You want the black one.
I'm assuming you also have an amplifier for your subs and the necessary wiring. You will need to run a 12v+ from the battery to the amplifier, splice a power-on signal wire from the ACC Power wire on the stereo's wiring harness (red wire) as well as connect the amp to the stereo via the RCA outputs.
the connections to the amp seem to be all wrong .check the wiring again.Does your deck have a seperate sub woofer output ?If it does , just connect one sub, i repeat, just one sub,and see the output.
check the GAIN control on the amp.it should be 2/3rds of the max volume of the cd player.check it is not zero!
Set the amp to the L.P.F. position.
bye .happy listening.
