- Key Specs
- Continuous Watts x Channel @ Ohms: 45 Watts x 4 @ 4 Ohm
- Amplifier Class: D (An amplifier's mode of operation, specifically the conditions in which its electrical current flows for the duration of an audio signal, determines its class. Each class has its strengths and weaknesses when it comes to power efficiency, levels of crossover distortion, and overall sound quality.)
- Number Of Channels: 4
- Bass Boost: None (Circuitry that boosts the bass response of the amplifier, improving audio reproduction enhancing the sound of low frequencies. Fixed boost means the level of bass response is preset, whereas variable boost allows the user to make adjustments.)
- Bridgeable: true (Bridging an amplifier increases the power it supplies to the speaker(s).)
- Low-Pass Crossover: Variable (Devices with this function allow only audio frequencies below a chosen cut-off frequency to pass through to a speaker or sound system. A device may have a cut-off frequency predetermined by its manufacturer (fixed), multiple cut-off frequency options to choose from (selectable), or have the capability for the frequency to be configured by the user (variable).)
- High-Pass Crossover: Variable (Devices with this function allow only audio frequencies above a chosen cut-off frequency to pass through to a speaker or sound system. A device may have a cut-off frequency predetermined by its manufacturer (fixed), multiple cut-off frequency options to choose from (selectable), or have the capability for the frequency to be configured by the user (variable).)

A: Plug and play in the sense that you if: - you do not have an aftermarket head unit with pre-amps, you can still splice the RCAs to your factory wiring harness (but i wouldn’t recommend that, as it would be better to get an aftermarket stereo wiring harness for your unit, they provide more standard color coded cables to splice to, then splice from the RCA to it) - you do have an aftermarket head unit with pre-amps (this means you should already have an aftermarket stereo wiring harness), you can just connect the RCA cables (which are included) from your head unit to the amp Once the audio wires are successfully routed from your head unit to the amp and then back to your harness, all you have to do is: - splice the remote wire (blue) and power wire (yellow) to the stereo wiring harness - splice the ground wire (black) to the stereo wiring harness or ground it to your chassis This process may seem tedious and time consuming, but will save you $ and is also a good way to get into DIY car audio. There are plenty of walkthrough videos on YouTube that you can reference when performing this process, as it is pretty standard. Lastly, if this sounds like it’s out of your comfort zone, Best Buy does provide geek squad installation services (which in my area cost around $130) but you may have to wait a while (sometimes up to a month as they get backed up with orders) in order for them to get to your install. Hope this helps :)
