u/Abject-Court-9275

I replaced all the door speakers in the whole truck, hooked up an amp bypass harness… I’m getting real low sound out of both front door speakers.

When I disconnect the bypass harness and hook amp back in, along with factory jbl Toyota stereo… it sounds good.

I tried two different aftermarket head units and both have poor sound out of the front..

Wondering if anyone has an idea on what I’m missing? Thanks
