A Class D 5-channel powerhouse

Jensen's Power 1500.5D 5-channel amplifier will pump up your whole system with 58 watts RMS to four separate full-range speakers, plus up to 340 watts RMS to a subwoofer. This small but powerful amp will fit in a lot of different places in your vehicle, so you'll have plenty of installation options. A plastic sleeve encapsulating each power and speaker connector eliminates any worries about short circuits.

Adjustable for perfect sound

The Power 1500.5D comes equipped with frequency filters so you can shape the sound to best fit your speakers and sub. The subwoofer section includes a bass boost if you want some extra thump, and a wired remote level controller to dial in the right amount of bass from the front seat.

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Features

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
Note: The following manufacturer's power specs, displayed on the box and in the manual, are measured @ 2% THD+N, 1 kHz, and 14.4 Volts DC:
  • 60 watts RMS x 4 channels + 230 watts RMS x 1 channel into 4 ohms
  • 90 watts RMS x 4 channels + 400 watts RMS x 1 channel into 2 ohms
  • 190 watts RMS x 2 channels (bridged stereo) into 4 ohms

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.

Note: A 6 AWG power wire is recommended for installing this amplifier. Since 6 AWG amp wiring kits are not very common, a 4 AWG amp wiring kit can be substituted for a 6 AWG kit. A 60A fuse should be substituted for the fuse supplied by the 4 AWG kit.

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.
