Features

Overview: The CP208LG-W3v3 MicroSub is a compact bass solution for vehicles with limited space. This slot-ported enclosure is loaded with two 4-ohm 8W3v3-4 woofers, internally wired in parallel to present a 2-ohm load.

Enclosure Design: The enclosure features top quality MDF (medium density fiberboard), cut using state-of-the-art CNC woodworking equipment, and covered with high grade automotive carpeting. Extensive interior bracing permits the use of thinner MDF that maximizes the enclosure's internal volume relative to its exterior volume. Each driver has its own airspace and is protected by a black steel-mesh grille.

Flared Ports: The enclosure has side firing slot ports. The flared port opening minimizes turbulence and improves overall fidelity. The ports are 1-1/2" high and 4-1/8" wide at the openings and wrap around two walls of the enclosure to produce the necessary low tuning frequency.

Driver: The 8" W3v3 drivers have the following features:

  • Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method aimed at improving dynamic motor behavior. As a result of DMA optimization, W3v3 motors remain linear in motor force over a very long range of excursion, and also maintain a highly stable fixed magnetic field in the gap over a wide power range. The result is vastly reduced distortion, faithfully reproduced transients, and tight, clean, articulate bass.
  • Floating Cone Attachment Method (FCAM): JL Audio's patented FCAM technology is an innovative method of bonding the surround/cone assembly to the voice coil/spider assembly. This assembly technique ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.
  • Vented Reinforcement Collar (VRC): The Vented Reinforcement Collar is a composite structure that addresses two issues related to reliability. By reinforcing the critical junction between the cone, voice coil and spider, the VRC greatly reduces failures due to glue breakdown or material weaknesses. It does this by greatly increasing adhesive contact area and providing stress relief to the spider material at excursion extremes. the VRC also feature slots that facilitate air flow directly onto the voice coil windings to reduce thermal compression effects and enhances reliability.
  • Spider/Lead Wire Assembly: The W3v3 features a unique spider, coil and terminal subassembly which is assembled prior to installation in the speaker frame for optimum alignment and glue-joint integrity. The spider is insert-molded into a composite carrier tray which also incorporates the terminal assembly and lead wire strain relief features for enhanced reliability and optimal alignment of parts. The flying lead wires are carefully controlled and strain-relieved without resorting to woven-in lead wires, which can degrade spider performance.
  • Elevated Frame Cooling: The elevated frame design of the W3v3 delivers high-velocity air flow through slots directly above the top plate to the voice coil of the speaker. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.
  • Surround Stress Relief: By creating a radiused feature on the edge of the cone, stress is relieved from the surround material at maximum forward excursion, resulting in longer life and more consistent surround behavior.
  • Customizable Trim Ring: The woofer comes with a removable ring made of black ABS plastic which can be painted to match the installation theme and create a personalized look. You can purchase optional grille mesh inserts which are specifically designed to fit into the inner diameter of the trim ring.

Will this fit a regular cab 2014 Ram 1500?

We have not have a measurement for the available space for a subwoofer box in your 2014 Ram 1500 regular cab. The measurements for this enclosure are 36"W x 11"H x 6-1/4"D. I recommend checking the space in the truck to compare with these measurements.

We do not qualify universal subwoofer boxes like the JL Audio CP208LG-W3v3 for specific vehicle fit, Angel. We advise taking accurate measurements of your desired location and comparing to the listed specifications on the JL Audio enclosure. I have listed those measurements below to help, and any items that simply do not fit after due diligence in measurement can be returned for a refund within the first 60-days. JL CP208LG-W3v3 dimensions: 36" Wide 11" High 6-1/4" Deep

We do not measure universal boxes like the JL Audio CP208LG-W3v3 for specific vehicle fit, Raymond. If you are considering installing the JL Audio subwoofer, we advise measuring your available space carefully and comparing to the dimensions I have listed below for the JL box: 36" Wide 11" High 6-1/4" Deep. Space is limited in the quad cab, and we do not have any truck specific JL Audio options like the Stealthbox available. I hope this helps!

Q
Will this fit in a single cab 2000 s10?
aaron murray  Sep 22, 2022
1 answer
A
Greetings Aaron, and thank you for your question. Its going to be pretty tight. The JL box is 6.25 inches deep on the bottom, and the top. We measured the S-10 at 6.5 inches by the floor, then up 22 inches where you would have 4 inches. The JL box is only 11 inches tall. Im thinking it will, but be right up against the seat.

Q
Can this fit in a 1996, 2 door Chevy cheyenne? And would I be able to put it on the back of the seat instead of the bottom of the seat?
ivan  Jun 17, 2022
1 answer
A
Based on our measurements of the space behind the seats of a 1996 Chevy Cheyenne, this will likely be a bit too large to fit. Nevertheless, our advisors are happy to discuss fit and consider other options at 1-800-324-9695.
zachary  Jun 17, 2022 (Staff)
Q
Do you think this can beat in sound quality one 12" from other brands like Sundown ? Can this reach that low ?
nelson solano  Nov 17, 2021
2 answers
A
Sound quality yes. It wont play as low as a 12, but its solid bass. I listen to old rock, 70's and 80's mostly and the bass is right there. I dont listen to rap or try to entertain the neighborhood with my stereo but it will crank
wayne  Nov 17, 2021
A
Sound quality is great. It will not get as low as a 12 due to frequency response. Sound output is about same due to cone surface area. If you listen to more hip hop/rap then get a 12 inch with alot of xmax such as a sundown or JL W7. I listen to everything and this has surprising output even for hip hop music. I have this in the back of a Tacoma double cab and now in my WRX STI being powered by an old Rockford Fosgate BD1000 with the bass knob (I have the non self powered version). I rarely need to use the bass knob except maybe some classic or 80-90s rock.

You will need to take some measurements of the space you have to determine this.

I would contact jail audio themselves since they make the box and ask them I'm sure he could probably work something out

How long do you expect this system to last ? I had the CP108 version and it lasted only 6 years
nelson solano  May 03, 2020

I've had mine for over 3 years powered with a Fosgate BD1000. If the gain is set proper it should last quite some time.

Yes as long as you pair them with an appropriate amp.

Not sure you will probably need to tape measure the height of the back seat compare with the size of the speaker cabinet
nojir  Mar 06, 2019
A
Yes! If I could buy the speakers again, I'd buy two 10s

Q
Will this fit under the 2nd or 3rd row seating in a 2001 Ford Excursion?
joshua  Feb 25, 2017
1 answer
A
Probably as long as the inside measurement under the seat from bracket to bracket match outside diameter of the box. We fit one under the rear of an f-150 but the seat sat up a little because of the hump in the center.

Q
Would this be loud enough in a jeep with the top off? Obviously with a proper amp.
troy  Jan 29, 2017
2 answers
A
YES plenty of sound
marciano  Nov 17, 2021
A
When properly powered, the JL CP208LG-W3v3 should produce plenty of volume in a Jeep with the top down. If you would like to discuss further, feel free to contact an Advisor directly by phone (1-800-324-9695) or online chat.

Q
Will this fit under rear seat of 2014 Jeep Wrangler Unlimited?
troy  Jan 29, 2017
1 answer
A
I'm afraid we don't have any information on the available space under the rear seats in your '14 Wrangler Unlimited. However, the JL Audio CP208LG-W3v3 measures 35-1/2" (width) x 11" (height) x 5-1/8" (depth) if you want to try and measure the space on your own to verify fit. If you would like to discuss further, feel free to contact an Advisor directly by phone (1-800-324-9695) or online chat.

Q
so all i need is an amp that runs 500w rms to the sub? theres only the one terminal?
blake  Jan 20, 2017
2 answers
A
There is only 1 terminal pair input (1 positive/ 1 negative). [I'm running a 5 ch JL amp. Using 4 of the channels for the door speakers, and the last channel is 300wx1 at 2ohm. Plenty of power for me. Shakes mirrors, hits hard.] If you just want to power this sub, a mono (1 channel) sub would do the trick. 500w at 2 ohm would be a lot of power.
ryan  Jan 21, 2017
A
Yes there's only the 1 terminal but with 500 w job amp put both outputs to the one speaker input and spearkers sound good. Have the same setup in my 2016 f150 and it sounds good for 2-10's.
paul  Jan 21, 2017
Q
Can I use a JL XD 1000/5v2 on these 2 8"s and my front and rear doors? The Rms for the sub out is 600w. Will that be pushing them to hard if it's turned down?
long  Oct 17, 2016
1 answer
A
Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system.

Q
How much does this dual JL 8w3 enclosure weigh loaded with both woofers(non amplified)?
chris  Oct 01, 2016
1 answer
A
The weight of the JL Audio CP208LG-W3v3 alone isn't provided--however, the shipping weight (including the box its shipped in) is 36lbs. So the enclosure and dual woofers are likely somewhere between 32-35lbs. If you would like to discuss further, feel free to contact an Advisor directly by phone (1-800-324-9695) or online chat. I hope that helps!
david  Oct 05, 2016 (Staff)
Q
Would the JL Audio XD700/5v2 5-channel car amplifier work with this sub? I want to run my JL Audio c5-650 component front speakers and and rear speakers with 4 of the channels and run this sub with the 5th channel. Will the XD700 be powerful enough for this sub?

500 watt rms powered amplifier at least if not more for headroom
marciano  Nov 17, 2021

I have the JL Audio JX500/1D with the bass control knob. A quality amplifier of this output should do.
jose a  Jun 23, 2014
A
I went with the Pioneer GM-D8601. It is 500 watts at 2 ohms and comes with the bass boost know while only being $200. It sounds Great in the back of my 2005 4runner. Highly recommended for the price. Hope this helps.

For details on installation please contact an Advisor by phone or online chat. They will be able to pull up your vehicle and give you the details on what you will need for an installation. If you run into any issues during installation our Tech Support team will be happy to help.

As this is 2 4 ohm subs could I just pull them and rewire them to run 4ohms on 2 different channels?
alex  Dec 30, 2013

A
Contact JL Audio for this.
marciano  Nov 17, 2021
A
This would not be recommended as you would need to add a separate set of terminals for the second subwoofer wiring (which would mean modifying the box). For details on a sub box that might fit your needs please contact an Advisor by phone or online chat.
