## Description

JBL Stage 9603 3-way Speaker, 6" x 9"

Review: Great Priced Speaker! - Just installed these JBL 6x9's on my 2020 Tacoma front doors. Blows the factory junk speaker away. Very happy with the sound quality using stock receiver. It amazes me the size of the magnet on the Factory speakers tha I took out compared to the new JBL's. Now looking to do the back doors with the 6 1/2 JBL's very easy install using the Metra speaker adapters and quick connect speaker wire harness. I see some bad reviews but not sure what their issue is but I'm happy. Lots of brand options and happy with my New JBL's.
Review: WORK GREAT!! - These work great!! Especially for the price. I am only running these 2 in my video. I seen other reviews saying they didn't or they didn't have bass. I'm guessing those people wired them backward. These have great bass and I am just running a cheap Kenwood 50w per speaker head unit. I would love to hear these at 100w per. If you looking for a good quilty speaker for a low price these are it!

## Features

## Questions & Answers

**Q: Well it fit dodge neon rear speaker it says 6 x 9**
A: If it says 6 x 9 it’ll fit

**Q: Should my 6"x9" 3 way jbl speaker box be ported or sealed?**
A: Depends on displacement and max power of the system.  Sealing is done to limit rattling.  Port size depends on cone travel.   If you seal the box port is critical, if mounting is done in a box that has manufactured gaps for the watt and size rating ports are less vital however I employ a port to dampen cone movement and improve bass response.   (6” or greater woofer/subwoofer is not optional)  252” / 7” = 1.5” per 100 watt channel.  @ 1” inch it dampens sound so use some box sound management foam or carpet to create a smooth sound that won’t allow the speaker to make that plastic pop sound playing a deep bass high cycle rythym

**Q: how are these compared to the stock speakers on a 2006 ford escape hybrid? how well do these handle bass?**
A: Like a bassassman

**Q: Would these speakers work in my speaker lids on my motorcycle?**
A: Not sure! Sorry

### ⭐⭐⭐⭐⭐ Incredible
*by A***G on July 27, 2023*

We installed these in the rear deck of my sons 2003 Honda accord coupe and they are incredible. Good deep bass clear crisp highs. No distortion at hi volume. He has an aftermarket head unit with 18w x 4 channels and these with the stage 3 6.5” door speakers shake the rearview mirror. I am extremely impressed. Back in the 1990’s in the south we called it hum. Man does his car have some hum in it now. If you are looking to replace your factory speakers and don’t want to mess with amps you will not be disappointed. Just make sure to match the rms watts and ohm rating as close as you can to your factory speakers if you are using the factory head unit. Get these you will not be disappointed.
