    JL Audio 400-watt, 4-channel Class D full-range amplifier is for those of you that have a 1987 and up Wrangler, and are looking to add an amp either to power speakers and/or a subwoofer. This is going to be a very compact amp, while still being very high-power. Because this is a four-channel amp, it gives you the opportunity to run multiple components and multiple types of components through it, and it is going to provide 400 watts of power. So even if you're trying to drive a larger subwoofer, this is going to have more than enough power. Now, JL Audio does make a very high-quality component. This is going to be something that's a little bit more expensive than some of the other amps out there. But if you are looking for quality and you have the budget for it, this is going to be a good option. Like I said, one of the big benefits to this amp is that it's big power in a small package. This is a fairly small chassis for a 400-watt, 4-channel amp. This is going to have a couple of different pre-ins and pre-outs. You're going to be able to bridge your two channels and other two channels together to give you even more power per channel. This is going to put out a total of 75 watts per channel if you're using 4-ohm speakers, or 100 watts per channel if you're using 2-ohm speakers. This is going to give you a lot of power and be a very flexible system. One of the big benefits to this amplifier right here is that if you take off the cover, it does have LED clipping indicators built right into it. So without any other audio equipment, you can go ahead and make some adjustments, or make sure that you're getting the proper frequencies and the proper amount of power to each of your components. As far as the install goes, I am going to give this a one out of three wrenches. It's going to be a pretty easy install. You are going to have to pick a spot that, of course, is dry and clean for you to mount your amp. That's something that you're not going to have a problem with in a lot of cars. But in your Jeep, if you do a lot of off-roading, again, you want to keep this away from moisture and also away from dust. Once you have a spot to mount it, go ahead and mount the amp. Then, you're going to have to power it in, and also power it out. If you're not somebody who's comfortable with automotive audio, maybe you want to take this to a shop and have them install it. However, if you do decide to tackle this on your own, it is going to be a pretty easy install with just some wiring tools. This amp here comes in at right around $300, which I do think is a pretty fair price for what you're getting here. As I said before, it is going to be a very small package, putting out a lot of power, and JL Audio does make a premium item, so the price is going to be a little bit higher than some of the others out there. If you're looking for something a little bit more budget-friendly, and you're not looking for all the bells and whistles that this has, those options are out there as well. But if you're looking for the top of the top, this is where you want to look. So if you're looking for a very high-quality amplifier, this one from JL Audio is going to be a very nice option for you, and you can find it right here at extremeterrain.com.

    Impeccably Clear Audio. The 4-Channel Class D Full-Range Amplifier from JL Audio delivers crystal-clear audio efficiently within your Wrangler YJ, TJ or JK reliably using exclusive NexD Switching Technology and differential-balanced outputs. The 4-channel amp powers 75 watts RMS through your Jeep's speakers with low distortion, and offers studio-grade signal processing with high- or low-pass 12 dB/octave filters per channel pair. When you want to change it up, switch to a 2-channel or 3-channel mode with the amp's input type switches that bridge stereo output channels without any Y-adapters required.

    Compact Amp. JL Audio proves that a large chassis is not a requirement for a powerhouse amp. The Class D full-range amplifier is ultra-compact, featuring all controls conveniently on the amp's top; with its dimensions of 2.12"H x 9.78"W x 6.96"D, this amp won't take up much space in your vehicle's interior. The amp is protected within a sleek black powder-coated casing and has a dual-color LED light on top to show condition and status at any time. Enjoy being able to automatically turn it on too, via DC-offset sensing or signal sensing.

    LED Clipping Indicators. The RD400/4 amp comes with LED clip lights, which you won't get with just any amp. The indicators enable you to set the amp's input sensitivity settings easily and fast, without having to break out any special tools. Once you determine where to safely mount the amp in your Wrangler, follow the included instructions to install it, which includes running power wire from the disconnected battery to the amp.

    Application. The JL Audio 4-Channel Class D Full-Range Amplifier fits 1987-2018 Wrangler YJ, TJ, JK and JL models only.
