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 16 for details.
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 HD600/4's "+12 VDC" and "Ground" connections are designed to accept 4 AWG power wire. 4 AWG pure copper wire is recommended for any power wire run longer than 72 inches (180 cm). For runs shorter than 72 inches, 8 AWG pure copper power wire is acceptable
