HI everyone,
i recently bought 04 rx8 and decided to put aftermarket head unit in, everything went well until it time to test:
everything powered up like it should but the only thing im having issue with is the sound. the unit turn on and play but i have no sound at all. i have checked all the fuse and making sure all wire connected correctly but still didnt find the problem.

If anyone have installed aftermarket head unit on their car or know what is going on please let me know.

im not sure if this is the right forum or not cuz this is my first time using it.

here some info:

Lagacy head unit model #: LDN7U
Metra kit single din
bose premium sound
