Panasonic wired correctly including factory sub... Protege5 sounds great until you turn the headlight switch on...Any ideas? TIA
Radio buzz when headlight switch is on?
- Thread starter BUCK ROGERS
- Start date
Solution
Its from the Dash Lite Resistor roller switch, so when u dim Dash Lites 100% no buzz - Now yes that switch or dash Lites may have ground problem.

Are you using the dimmer circuit to power the deck? It’s been a while since I’ve looked at wiring diagrams for stereos

I would try to quickly disconnect the head light bulbs and see if that clears it up. If there’s aftermarket LED bulbs it could be poor quality or bad resistors and such on that circuit.

- & It buzzed fm Dimmer before LED Hi/Lo 's & LED Hi beams & LED Fogs I installed

Just looking at those red connectors and tape makes me cringe...I work as a mechanic in the transport refrigeration industry and I rewire components constantly due to environment and 3rd world repairs... I mean no offence to whoever installed that.
you have some feedback on the circuits...so we need to eliminate all bad/ poor connection points and such. if it was me I would start at the head unit and rewire it with proper shrink tube and connections and make sure all your grounds are good... then I would check that SUB and the wires there to make sure nothing is cracked and such. Alternatively if you have another deck you could check that and determine if the head unit is bad.
I would also eliminate the dimmer option and make sure it runs fine. then check that circuitry. its possible you need a series of resistors to smooth out that line.

No... we bought this for Son In Law to save gas expense in his V8 Toyota Truck so I wont see it until next Oil Change - First thing I'm gonna do is jumper out Dimmer Resistor to put Dash Lites on Hi w/no resistor inline & see what happens.

I saw on Amazon a variety to 12VDC line voltage filters... you could try that on the power supply side on the dimmer circuit to the deck. for $12 could be an option.

no sorry - GF's son driving it 100 miles a day & loves it - His wife got T Boned in her Van so she's driving his Truck hence Mazda's not stopped long enuff to investigate - he doubled his gas mileage versus the V8 Tundra.

So glad you got it sorted out Buck! I was waiting on this conclusion lol.

So I mess around trying to jump it out at Connector,,, blow a Fuse of course... THEN figure out if u just disconnect the dimmer Dash Lites default to ON.
