Being as I do not have a manual with my deck, and I cannot find a friggin online manual, maybe someone here can help me.

I have the Sony CDX-C7000X

1. one thing that is bugging the hell out of me, is that 3 seconds after shutting off the car, the deck sends an output to the speakers of 3 sets of beeps. In the MENU there is something called BEEP and I have it off which disables beeps from chiming when touching buttons on the deck, but how in the HELL do I disable that damn chime.

2. There is HPF and LPF controls on the deck (Off, 80, and 120) that do not seem to do anything to my subs. My friend that used to have the deck says that there should be a noticable difference. On my amp I have also an LPF, HPF, and OFF dial, and right now it is on LPF. Will changing it to off allow the deck to control it?

3. Does anyone know a place online that will have this manual for free?

Thanks in advance!
