The display screen says protected and there is a weird low tone sound from the sub woofer and nothing works! The unit stays on for a few seconds then turns off automatically. The manual said to reset it by turning it on then off and hold the SRS WOW button for more than 5 seconds. Ive tried that and it did not work still the same, the screen read protected. I even tried to pull the plug out and leave it out for a few hours but no change the screen read protected!!! Any help would be greatly appreciated!
By your description it looks like an internal protection has tripped. The reset will not work if the unit is fried. Did this happen when you were pushing the unit really hard or distorting it? You may have to have it repaired, or replace it. Repairs can sometimes take a couple of months so be wary of this.

Either the sub woofer speaker or the sub woofer amplifier section circuit has the fault. Contact any service technician to make diagnosis the faulty section. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/

are you getting any sound at all out of your sub woofer? what about if you bypass the EQ? If you're getting sound but just not the control over it then the Potentiometer (the volume knob) is bad or has become loose from the connection to the board. More than likely you would not have any sound at all if it's loose. If you have no sound and you are not getting sound after bypassing the EQ then check your head unit settings to make sure that it is set to have full frequency output of the RCA's. It may be set for high pass which will filter out the low tones, leaving nothing for the EQ to work with.

When you touch tone button on your front panel repeatedly, you will get two option for setting bass and trebble, when you select Bass immediatly press your updown Sound field Program Button.
Please note:for better sound if your using Small front speaker keep bass to 0db and select the low frequency through sub woofer and program manually LFE from only Sub woofer and addjust CUT off frequency of Subwoofer to 160 and incase if your bass is not clear put it into rev mode.
> checked resistance getting nothing Nothing = zero or nothing = infinite? If it is essentially zero, you are probably OK since the DC ohms of nearly any speaker measures very low resistance; they are rated in impedance which is a complex combination of resistance (R), inductance (L), and a little capacitance (C) and becomes the 'Z' of the rating of (typically) 4-8 ohms. If it is measuring open (a flashing display on any resistance range of a digital meter), then you probably have a problem. You can safely take a single flashlight battery (or any 1.5 volt cell) and apply this by tapping across the input of your sub-woofer.If it makes a fairly loud 'click' then the speaker is functional. If it passes the test, you have connection or output problems from your amplifier.
