Product Research

Features

Woofers: Each JL Audio C1 speaker features a mineral-filled, injection-molded polypropylene woofer cone with a rubber surround.

Tweeters: The 3/4" edge-driven, aluminum dome tweeters are damped by a silk surround suspension.

4/2 Hole Compatibility: Most 4" factory speakers use four mounting screws, however, in some vehicles, only two are used. The C1-400x's mounting tabs can be removed, allowing installation in 4-hole or 2-hole applications. Care should be taken handling the speaker after any tabs are removed because the broken edges may be sharp. Please enter your vehicle information to confirm fit.

Power Handling: JL Audio publishes several power specifications for this speaker, 35 watts continuous power handling (RMS), 105 watts peak music power, and 10-50 watts recommended amplifier power (RMS). We've listed the conservative combination of 10-35 watts RMS in the specs table.

Customer Q&A

4 questions already asked

Q
What is the distance between the mounting holes. This is going on a 2003 Honda GoldWing and the holes need to be exact ?
tom  Sep 10, 2023
1 answer
A
We do not have any information in our system on your 2003 Honda Goldwing sadly Tom, so we cannot guarantee any speaker fitment. That being said, these JL Audio C1-400x speakers are a good choice as the mounting holes are open ended, with a wide variance of fit possibilities. We measure the inside and the outside of the slotted tab also for accurate fitment in situations like yours. The inner diagonal measurement is 4.381" (the inside edge of the hole diagonally) the outer diagonal measurement is 4.95". I hope this helps!

Q
Can the mounting tabs be bent without them snapping off? My Toyota uses 2 mounting screws and one tab needs to be bent forward in order for the speaker to sit flush.

A
Hypothetically, this should be possible. However, our advisors are happy to review your project in greater detail to see if there will be any issues. Please reach out to us via online chat or phone at 1-800-324-9695.
