Sub woofer keeps going in and out. I have two subs and had the same problem with both. I put them on my stereo and they work fine,,,

You can connect the two 6x9 speakers to the two individual left and right outputs of the car stereo.
Connect each of the left and right channel with the correct polarity . Now the Sub-woofer requires an amplifier to be connected separately and so you need to use the car stereo to be linked to a sub woofer amp which powers the sub woofer.

Turn the amplifier on.Go to audio menu select sub-woofer mode to on position.It should solve the problem

hi,
if u want to hook up the sub with ur av receiver the connect the sub woofer output of ur AVR to any one (left or right) input of ur sub woofer. then connect its power . set the frequency range between 90 and 120Hz. set the volume of sub woofer to 40% of its total. also check the av receives speaker setting. goto speaker setup and make ON the sub woofer out.

if want to connect the sub to a stereo amp without sub out. then connect the amps speaker line to the speaker input of sub woofer and connect the speaker out of sub to left and right speaker ( make sure to connect the red to red and black to black). set the volume and frequency as above
ok

check the cable for you sub woofer. If problem exists. Try another cable to verify. What kind of subwoofers are you using? Are you going through the LFE port or are you running speaker wires through the speaker inputs on the sub?

It sounds like you have switched off the sub channel.
Keeping pressing C Level on the remote till you see SWFR.
Press D l / h to adjust the speaker output
level.

You can get rca jack ends at any electronics store.So no you don't need a new sub.

i put a new stereo in was working fine ater about 20 min speakers stoped working but the sub-woofer is still working

Your sub woofer is not mean for voice sound...check that you have connected the systen up properly and that you have put the sub woofer into its wn connection..if it is in the right connection the woofer could be blown.also try decrease the midrange hurts on the woofer

Chances are if The Receiver only has sound in Stereo Direct Mode and all surround modes and Sub out are Inop the DSP (Digital Signal Processing) Card is most likey defective. These boards are not available from marantz (D&M Holdings) and must be Component level repaired which usually is not cheap. If Only the Sub out is not working check setup to be sure sub woofer is set for on. Also If On Screen setup menu does not appear on video monitor Unit may need to be Reset manually which entails discharging a Capaitor on main P.C.B Contact [email protected] for details
