5-Channel Full-Range Amplifier: The Jensen Power 1500.5D is a five-channel, class-D amplifier, designed to run front and rear speakers and a subwoofer. It comes with a Remote Input Level Control that allows you to vary the volume of the subwoofer channel from the front seat of the vehicle.

CEA-2006 Compliant: CEA-2006 is a system of testing and measurement methods for mobile audio amplifiers. This voluntary standard advocates a uniform method for determining an amplifier's RMS power output and signal-to-noise ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts and the RMS power output is measured into a 4-ohm load at full 20-20kHz bandwidth with 1% or less Total Harmonic Distortion plus noise (THD+N). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. CEA-2006 allows consumers to compare car amplifiers and receivers on an equal basis. Following the CEA-2006 criteria, the power ratings for the amplifier include:

• 58 Watts RMS x 4 channels + 215 Watts RMS x 1 channel into 4 ohms @ <1% THD+N
• 87 watts RMS x 4 channels + 340 watts RMS x 1 channel into 2 ohms @ <1% THD+N
• 180 watts RMS x 2 channels (bridged stereo) into 4 ohms @ <1% THD+N

Controls

Independent Gain Controls: The Power 1500.5D features independent rotary gain controls for the front, rear, and subwoofer channels. The line inputs will accept signals between 400mV and 5.0 Volts.

Crossovers: The amp has independent crossovers for the front, rear, and sub channels. The front and rear channels each have a continuously variable high-pass filter with a cutoff frequency of 16Hz-160Hz. You can defeat the crossovers via a 2-way switch by setting them to "Flat". The sub channel has a continuously variable low-pass filter with a cutoff frequency of 30Hz-160Hz. The low-pass filter cannot be defeated.

Input Mode: The Input Mode can be set according to the RCA line inputs connected to the amp. A 2-way switch lets you choose between 4CH and 5CH modes:

• 4CH: For head units without a separate subwoofer output, you should select 4-channel mode. The subwoofer channel is a sum of Front L, Front R, Rear L, and Rear R.
• 5CH: For head units with a mono Subwoofer output, you should select 5-channel mode. The subwoofer channel is a sum of both sub RCA inputs.

Bass Boost: The amp features a continuously variable Bass Boost on the subwoofer channel, adjustable from 0 to +12dB, and centered at 45Hz. This allows different subwoofer/enclosure combinations to be equalized. The control lets you increase the level of low bass available from the subwoofer/enclosure combination. Ported and Bandpass enclosures should be limited to about +6dB to +9dB of boost, while sealed enclosures should be able to accept the full +12dB of boost, if necessary.

Connections

Power/Ground/Turn-On Terminals: The amplifier features set-screw terminals for the power, ground, and remote turn-on connections. The Power and Ground connections will accept up to 4 AWG power wire, while the turn-on lead terminal will accept 18 to 8 AWG wire. A Phillips-head screwdriver (not supplied) is required for tightening or loosening the set-screws.

Speaker Output Terminals: The Power 1500.5D amplifier's ten set-screw speaker terminals will accept 16 to 8 AWG speaker wire. A minimum of 12 AWG speaker wire is recommended by the manufacturer. A Phillips-head screwdriver (not supplied) is required for tightening or loosening the set-screws.

Preamp Inputs: The amplifier features 3 pair of RCA jack inputs. The Input Mode switch should be set according to the Line Input connections.

Remote Input Level Control: The amplifier features a 3.5mm connector for connecting the supplied wired Remote Input Level Control. With Remote Input Level Control, you can control the volume of all channels from the front of the vehicle. If the amp is used to drive subwoofers, and the low-pass filter is activated, the Remote Input Level Control can be used to control the bass level independent from the rest of the system. The Remote Input Level Control has a 16.25' cable.
