Best Choice No. 1
Kenwood Excelon P-XR600-6DSP 6-Channel Car Amplifier with Digital Signal Processing and Maestro AR Interface
  • Many new cars equipped with premium amplified systems are nearly impossible to replace and very difficult to upgrade the audio performance. The XR600-6DSP when combined with an iDatalink Maestro AR can use a true stereo signal from the existing OEM stereo and translate all the CAN-Bus communication of the original radio to the XR600-6DSP. Integrates with many Chrysler, Dodge, Fiat, Ford, Jeep, Lexus, Maserati, Ram, Subaru and Toyota premium systems, with more vehicles to follow.
  • Use the KENWOOD DSP Control App (compatible with iPhone and Android) to setup the XR600-6DSP. The listening position, advanced equalization and filtering can be set during installation and the setting stored in memory. A simplified mode is available for day to day use.
  • The 32-Bit 192kHz DSP gives the flexibility of independent tuning and equalization that is required with the variance of speakers and location challenges being used in a typical system. The channel flexibility allows any function or tuning on all 10 channels making it one of the most versatile solution based amplifiers on the market today.
  • These HEX-type terminals can accommodate up to AWG 8 – AWG 12 speaker wire thickness for better signal delivery to speakers. The HEX type design allows for maximum tightening and contact onto the wire.
  • These HEX-type terminals can accommodate up to AWG 4 – AWG 6 battery and ground wire thickness for better voltage maintenance from the vehicle’s battery. The HEX type design allows for maximum tightening and contact onto the wire.

NVX MVPA6 Marine-V Series 6-Channel Bridgeable Micro Class D Compact Car Amplifier | 900W Total RMS
  • Don’t let the size fool you! The Marine-V Series Amplifiers packs a massive punch when it comes to power. Here at NVX, we know how important space is when installing anything aftermarket. The Marine-V Series Amps are capable of being installed anywhere and everywhere in your vehicle. Whether you are installing it in your motorcycle, UTVs, ATVs, boats, and golf carts, the Marine-V Series Amps will take up little space.
  • The Marine-V Series Amplifiers are created for outdoor vehicles. We want to make sure your amplifier is safe no matter the application. Most amplifiers on the market claim to be meant for boats, motorcycles, and other outdoor vehicles, but lack any real measures to protect their amps. Here at NVX, our marine amplifiers are truly ready for the elements and have an IPX67 waterproof rating.
  • The Marine-V Series amps are Class-D amplifiers, meaning they run at or over 90% efficiency. This efficiency is extremely high compared to Class-A/B amps, which run at less than 78% efficiency. So, what does this mean for you? This translates to smaller heat shrinks, less power draw from your vehicle’s charging system, and it makes smaller internal components possible, allowing the overall footprint of the amplifier to be smaller as well.
  • All Marine-V Series Amplifiers are fitted with 3.5mm AUX signal input to work seamlessly with our NVX Bluetooth controllers (like the XUBT4 or XUBT3). This also allows you to have a direct connection to your device’s headphone jack. As an added bonus, all Marine-V Series Amps come with a bass knob, allowing you to have full usage of a subwoofer if you decide to bridge two channels together.
  • General Features: RMS Power Rating: 4 ohms: 100 watts x 6 chans. / 2 ohms: 150 watts x 6 chans. / Bridged, 4 ohms: 300 watts x 3 chans. / Class-D FullRange 6-Channel Amplifier / Heavy-duty aluminum alloy heat-sink OR high-density split-dome convection heat-sink for extreme heat dissipation
