Non-Bose OEM speakers better than Hertz?!
 

I read a few times about people using Hertz, so I bought a set for my sedan. Installed the driver side to compare to stock and it sounded horrible. Are Hertz overrated or are the stock speakers pretty decent for being stock? When I removed the OEM, it weighted nothing and looked like it was built with construction paper.

I don't have the models offhand, but they're the basic sets, sub $200.

Anyone else have experience with upgraded their Non-Bose speakers?

Bose drivers are designed/spec'd to work with Bose amplifiers and equalizers. If you split the pair and use one without the other, you will get poor results.

that is true, but the OP said *NON*-Bose ....

Depends on what "sounds horrible" means.

Stock speakers are likely more efficient so would play louder than aftermarket and while Bose are 4 ohm if non-Bose are 2 ohm there would be more of a difference. If the Hertz weren't properly sealed to the door low end and mids would suffer. Phasing wouldn't make a significant difference if only listening to driver or passenger sides independently but would if listening together and Hertz are out of phase.
