Car mysterious audio problemo

[Adgey9]

I have a question about my truck radio. I put in an aftermarket radio to my 2005 Toyota tundra. The audio is trash. The speakers sound like a flip phone.
I assumed it was like that because of the factory amplifier that needed it to be bypassed but I looked in all the places The amp is supposed to be and also where it's not supposed to be and couldn't find one.
I hooked a factory speaker up to the radio and the sound was normal but when I hook it up to the truck radio /speaker wires It sounds bad.
I'm kind of at a loss. Maybe you could give me advice or I could even bring the truck in.
I Appreciate it

I'm sorry, but I can't provide technical support for car audio systems. You might want to consult a professional installer or technician for assistance.

What all did you swap out? Just the headunit (main stereo input), speakers, or both?

Also, what frequency range is it sounding bad? Are the high fuzzy or scratchy? Is there no bass? Do the vocals sound funny?

Simple answer is to bypass the OEM wiring. I wonder if the OEM stereo used a chassis ground for the speakers and that's causing you grief.

Just swapped out the head unit. I'm no expert but I don't think there's any bass

This could be it. There's a negative truck speaker wire that if you touch it to any of the radio speaker wires everything goes silent. And sound plays with only the positive wire as in you don't need both the negative and the positive to make the speaker work. And if I don't ground that negative wire the speaker creates a whining noise.

That's your issue. You need to run wires straight from your HU to the speakers.

But it only does that with one speaker. Are you saying that it can effect the sound of all 4 speakers?

I highly doubt that only one speaker is grounded to the chassis.

 

[Adgey9]

What if it's just an exposed wire to chassis from that one wire?

Then you would probably have intermit bad sound. Just rewire the one speaker if you want.

These are the four speaker pairs. The pair that is circled worked with just one wire and the wire exed out is the one that is grounded and when touched to each other all the speakers go dead
