Install help!!!

[matslp488]

Hello there.. trying to install this HU on my Trailblazer SS and still can’t figure it out… it powers on and everything BUT I’m not getting any sound from the front door speakers… I tried hooking up a speaker I had laying around up to the LF and RF speaker wire out puts and I’m only getting the tweeters to work but when I wire them up to the RL and RF outputs everything works fine… what I’m I missing here?? What can be wrong??? TIA

What can be wrong??? TIA

So the front outputs only play treble and the rear outputs play full range? If yes, then your radio may have that feature that filters the outputs. I know some Pioneer radios have it but do not know which ones.
The feature does exactly what you described.
Look in your settings or manual to see if this is the case.

That or with a TB, you either have an amp, or those early 2000 years on the full size tahoe, they were wiring them in series. It's most likely not the head unit, it's the stock wiring in the vehicle. Get some spare wire, and run em right off the head unit.
