Notes from JL Audio:
  • ¹If you connect a load higher than 4Ω nominal per channel in stereo mode (or 8Ω in bridged mode), power will drop by half with every doubling of impedance above 4Ω stereo / 8Ω mono. If you connect a load lower than 1.5Ω nominal per channel in stereo mode (or 3Ω in bridged mode, the amplifier protection circuitry activates a "safe" mode which reduces amplifier power to protect the circuitry from failure (the LED status indicator on the control panel will light up amber to indicate that this has happened). See page 15 for details.
  • ²When connected to the amplifier, the HD-RLC operates as follows. At full counter-clockwise rotation, the audio will mute completely. At full clockwise rotation the level will be the same as if the HD-RLC was not connected at all. In other words, it operates strictly as a level attenuator.
  • ²The RBC-1 Remote Bass Control used with JL Audio Slash, Slash v2, e-Series, A-Series and G-Series amplifiers is NOT compatible with the HD Series amplifiers. If you attempt to connect an RBC-1 to an HD amplifer, the control will not work. You must use the HD-RLC controller.
  • ³We do not recommend the use of "copperclad aluminum wire" or "CCA" wire because this wire is significantly less conductive than pure copper wire. Only use pure copper power wire, such as JL Audio's Premium Power Wire. Tinned copper wire (silver color) is acceptable as the tin-plating is only a very minor component of the wire.
  • ³The MHD900/5's "+12 VDC" and "Ground" connections are designed to accept 4 AWG power wire. 4 AWG pure copper wire is the minimum recommended wire size for this amplifier. Use of smaller gauge wire (including cheap wire that is fraudulently sold as 4 AWG wire) can create a fire hazard.

Great Amp, Small Footprint

The following review is for MHD900/5, which is a part of the bundle you are viewing.

This thing is a BEAST! It fit behind the seat of my Super Crew with ease and my system sounds amazing! I wish I had a little more juice for my subs (2 10" W1s) at times but I do not regret this purchase one bit. I love the look of my clean install with this amp and did I mention it sounds amazing?!?! Absolutely NO white noise, no hum, just raw power. Worth every penny.

Best Amp I have ever owned!!!!

The following review is for MHD900/5, which is a part of the bundle you are viewing.

I have owned everything from Polk Audio, Alpine, Kicker and most recently a Pioneer amp all in different vehicles with different setups. I replaced the Pioneer amp with this JL. Install was a breeze as it comes with connectors for the all the wires. Hardest part was figuring out where to mount the amp in the boat. Great design. Great quality. Would recommend it to everyone. Yes it’s expensive but well worth it.
