This kit includes the JL Audio CS112LG-TW3 12 inch TW3 loaded enclosure and an RD500/1 500 watt monoblock amplifier.

The CS112LG-TW3 is a loaded enclosure with a 12" TW3 subwoofer that has been wired to a 2 ohm load. The 12" TW3 subwoofer handles 400 watts RMS and has dual, 4 ohm voice coils. The sealed enclosure has a very low profile design with a depth of only 4.5 inches. The sealed enclosure is designed and optimized by the team at JL Audio for maximum performance from the TW3 subwoofer.

The TW3 subwoofers are among the best low-profile subwoofers you can buy. The output of these subwoofer is similar to the full-size W3, but the low-profile design provides much more installation flexibility. Many "shallow" subwoofers available for cars sound shallow. The JL Audio TW3 is one of the exceptions and delivers serious sub-bass output without sounding shallow. The CS112LG-TW3 comes covered with high-quality, black carpet with "JL Audio" embroidery and a subwoofer grille pre-installed.

The JL Audio RD500/1 amplifier delivers 500 watts RMS at 2 ohms, making it a great match for the 12 inch TW3 subwoofer. Since the TW3 is rated at 400 watts RMS, you want to make sure you don't turn the gain up all the way and risk blowing the subwoofer.

The RD500/1 uses JL's NexD switching technology to efficiently deliver power to your subwoofer. The RD500/1 amplifier is one of the best values among JL Audio monoblock amplifiers. The RD series amps are very similar to the more expensive, XD series. The RD amps are bigger, have cheaper internal components, and don't have JL's advanced thermal rollback technology. However, the RD amps come with LED clipping indicators. The LED clipping indicators allow you to determine where the radio clips on the input and where to set the gain on the amplifier to ensure that you never get a clipped signal. This helps extend the life of both your amplifier and your subwoofer while also providing a better listening experience, without distortion. The JD500/1 has a selectable, low-pass filter between 50-500Hz at 12dB/octave and accepts both high and low level inputs.

For quickly and easily adjust the bass level for each song and recording, don't forget to add the RBC-1 bass knob.

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.
