This package gives you a low profile 12" subwoofer, in a ported box, with an affordable, JL Audio amplifier that's a perfect match.

The JL Audio CP112LG-TW1-2 is a ported enclosure that comes with a 12" TW1 subwoofer pre-installed with a single, 2 ohm voice coil. The TW1 subwoofers are newer, lower profile versions of the W1 subwoofer and handle 300 watts RMS. The TW1 has minimal front-end protrusion and the enclosure comes with a speaker grille, pre-installed. The TW1 subwoofer handle 300 watts RMS and will surprise you with it's output. JL uses their concentric cone technology to mount the speaker motor closer to the front of the basket. This helps deliver full size output from a smaller, low-profile subwoofer. The ported enclosure is going to give you louder, boomier output than the sealed version of this package, CS112LG-TW1-2-JD250-1. The ported is also larger as it needs the extra enclosure room for the port, and by design, ported boxes are usually larger than sealed boxes.

The JD250/1 amplifier is both affordable and powerful. The amplifier puts out 250 watts RMS at 2 ohms, making it a perfect match for the 12-inch TW1 subwoofer. The JD250/1 uses JL's NexD switching technology, accepts both high and low level inputs, and it comes with LED clipping indicators to ensure that you set your gains at the perfect level.

Our Honest Take

This package is a great step-up option if you want a loaded enclosure, but you want something better than a W0. Also, if the W0 enclosure is big and bulky. If the W0 is too big for your vehicle, you can get the output of a ported enclosure while taking up significantly less space with the TW1. The JD250/1 amplifier is affordable and a perfect match when you look at the power handling of the subwoofer and the power output of the amp. If you want to step up to the JD500/1 or RD500/1, you can get more power from those amplifiers, but you will have the make sure you do not turn the gain all the way up. If you do turn the gain all the way up, you will blow the subwoofer.

What else will I need?

If you don't already have these items, you will likely need them for installation
  • An Amp Wiring Kit - If you don't already have an amplifier wiring kit, make sure to get one. With this amplifier, an 8 AWG kit will be able to provide the power necessary for the amp. However, make sure your wiring kit uses full-spec, OFC copper, and not copper coated aluminum (CCA). If you go on eBay, or to that company named after a jungle in Brazil, and see an amp wiring kit for really cheap, chances are it is CCA. This robs your amplifier of power and it increases the fire risk. Don't spend the money on a quality product like JL Audio and then cheap out on the amp wiring. That would be like putting pump gas in a race car. Our Classic Car Stereos 4 AWG & 8 AWG amp wiring kits use full spec, OFC copper wire and include a 17 foot RCA cable
  • Speaker Wire or RCA Cable for Input- If you buy our wiring kit, a 2 channel, 17 foot RCA cable is included. If you are using the high level inputs from your radio, you will need speaker wire to splice from your existing speaker wire, or to connect to the back of the radio.
  • Speaker Wire to RCA Adapter - If you choose high-level inputs, you will need speaker level to RCA adapters.
  • Speaker Wire - You need to connect your subwoofer to your amplifier.
  • Bass Knob (Optional) - Adding a bass knob lets quickly and easily adjust the level of your subwoofer. Every song and recording is different and so are the bass levels. The bass knob lets you adjust the bass to your personal preference, prevent distortion, and extend the life of your subwoofer.
