JL Audio Built In USA Great bass on your boat

The MX10IB3-SCR 10" marine subwoofer reflects JL Audio's commitment to top-quality engineering and sound quality. The sparkling chrome/black finish and "Sport Grille" design make it a perfect match for many boat interiors.

Built for life on the water

Built from the ground up for the marine environment, the MX10IB3-SCR sports a corrosion-resistant Centrex® polymer basket that surrounds the sub's internal structure for extra protection. The marine-grade synthetic fiber spider, injection-molded polypropylene cone, and synthetic rubber surround provide top performance, while shrugging off the harmful effects of sun, salt, and moisture.

The chrome-plated grilles look terrific, of course, but they're also durable enough to survive in harsh marine environments. That's because the plastic grilles are carefully prepped, then coated with four layers of metal substrate before the chrome finish is applied. The result is a deep, rich finish that's made to last.

Designed for a variety of enclosures

The subwoofer's motor structure allows extended cone movement, so you'll hear bass that's loud and low, yet precise and smooth. The versatile MX10IB3-SCR works in sealed enclosures, but it also works well in free-air applications, so you can mount it directly into a bulkhead if there's no space for a box.

Crutchfield Customer Review (What's this?)

Great bass. I have this subwoofer powered by a bridged 3rd and 4th channel off a Clarion XC2410 amp in my boat which has a manufacturer stated output of 150 amps at 4 ohms. It puts out plenty of bass. boat was vibrating my seat on some more bass heavy songs. The sub looks great too.

Pros: Great sound/bass Nice looking

Cons: None

JL audio all the way!!!!!

charlie g from Maryland on 10/31/2015

I love these subs and everyone in the water around me loves them.I installed 2 of these in my 21' bow rider with a m700/5 JL marine amp pushing them and 6 MX650 (matching grills) and my boat rocks. I've gotten so many people wanting to get on my boat to listen to the music and so many compliments on how deep and clear the bass is even from hundreds of feet away. My gains are only set at slightly past half. They have been installed for a full boating season now with many hours on them and i couldn't be more pleased.Thanks to the people at Crutchfield and JL Audio I have an incredible sound system. No question i will only buy JL Audio products from now on for my cars and boats

Pros: look great sound great grills are tough

Cons: could've used longer mounting screws for my application

"Wow! This sub sounds great!"

Crutchfield Customer Review (What's this?)

We had this sub installed about a month ago when we overhauled the original stock audio system on our 20' ski boat. Mounted it under the driver's side console just above floor, didn't need a separate box, powered by JL 5-channel marine amp. This sub hits hard! Very happy with the results, you can definitely hear us coming! Our fellow lake rats are blown away at how good it sounds. Top marine grade quality, from pop, rock, to Bassnectar... you won't be disappointed.

Pros: Clean powerful bass Premium quality, marine grade Looks sharp

Cons: A bit pricey, but you get what you pay for.


Hands-on research

Product Research


Marine Tested: JL Audio's marine subwoofers go through ultraviolet testing chambers (to simulate years of sun exposure) and salt fog chambers (to simulate years of exposure to salt-water environments) and are built to withstand the rigors of marine use.

Woofer: The subwoofer features an injection-molded, mica-filled polypropylene cone woofer with a synthetic rubber surround specifically formulated for marine use.

DMA (Dynamic Motor Analysis): JL Audio's proprietary Dynamic Motor Analysis (DMA) technology results in ultra-linear motor force over a long range of excursion and a wide range of power inputs to reduce distortion and improve sound quality.

Infinite-Baffle Operation: The M10IB3 is optimized for infinite-baffle operation so that it can be installed in a variety of locations, without the need for a dedicated enclosure.

Polymer Basket And Grille: The polymer basket and grille are corrosion and UV-resistant, and the basket encapsulates the motor assembly to prevent corrosion.

Connections: The speaker terminals are 0.25" wide gold-plated, marine-grade brass, male quick slide connections.

Mounting Hardware: Marine-grade stainless-steel mounting screws and washers are included.

Box Type: If mounting in an enclosure, JL Audio recommends a 2.5 ft³ sealed box (2.0 ft³ minimum). The M10IB3 should not be mounted in a ported enclosure.

Grille: The woofer is shipped with the grille attached (using three screws). The grille can be removed, but the woofer can be installed without removing the grille. If the woofer is mounted without the grille, several measurements are different:

  • Mounting Height: changes from 1.6" to 0.791"
  • Flange Height: changes from 1.125" to 0.5"
  • Frame Diameter: changes from 10.76" to 10.382"
