About the Pioneer GM-D9605
Cool power
Cool power
Pioneer's sharp-looking GM-D9605 5-channel amplifier can power your entire car audio system, sending 75 watts RMS to each of your front and rear speakers while delivering up to 600 watts RMS to your sub. Highly efficient Class D technology keeps this powerful amp running as cool as it looks, and allows for a compact chassis that fits in a lot of out-of-the-way spaces.
You can also create a strong front soundstage with bass by putting the GM-D9605 into 3-channel mode, sending 200 watts RMS each to a set of components up front, for example, plus 600 watts to a sub.
Connecting and tuning made simple
If your car stereo doesn't have RCA outputs, you can use the speaker-level inputs to hook this amp directly into your system. The amplifier switches on automatically when it detects the high-level input signal, eliminating the need to run a turn-on lead to your receiver. And the built-in high- and low-pass filters let you adjust the sound for your car's interior.

Features
CEA 2006 Compliant: The Pioneer GM-D9605 5-channel amplifier power ratings are measured according to the Consumer Electronics Association's CEA-2006 standards. These standards allow you to accurately compare the rated power output of all CEA-2006 compliant amplifiers, even from different brands. Manufacturers who adhere to the standards can display the CEA-2006 logo on their products and packaging. The amp has the following specifications:
- Power Output:
- 75 watts x 4 + 350 watts x 1 at 4Ω (with 1% THD+N)
- 100 watts x 4 + 600 watts x 1 at 2Ω
- 200 watts x 2 + 350 watts x 1 at 4Ω bridged
- Signal to Noise Ratio: 75 dBA
Class-FD Amp: A Class-D amplifier offers higher power in a smaller chassis than conventional Class-AB amp designs. Pioneer's exclusive Class-FD design not only delivers full-range Class-D amplification, but is more efficient than other designs. The result is clear full-range sound in a small amplifier. The ultra-compact design provides many installation options.
Channel Layout: The GM-D9605 is a 5-channel amplifier. The channels are labeled A (left and right), B (left and right), and SW (subwoofer). The left and right channels of both A and B can be bridged with an output of 200 watts (at 4Ω) for each, plus 350 watts for the SW channel.
Auto Turn-on: When using a high voltage speaker level input, a signal sensing circuit will automatically turn the amp on and off along with the source unit. This prevents the need for running a system remote control wire (turn-on lead).
Controls
Input Select Switches: The amplifier has two input select switches that allow you to choose the preferred input mode. For the A and B channels, the 4-channel mode requires that two pair of RCA inputs be connected to the amplifier's A and B inputs, while the 2-channel mode only requires one pair connected to the A inputs. If you have a separate RCA input for the SW channel, the SW Input Select should be in the SW position. If you do not have a separate SW input, the switch should be in the A/B position, and the SW channel will receive a signal from the A/B input.
Gain Control: There are independent gain controls for the A, B, and SW amplifier sections, each is continuously variable from 200 mV to 6.5 V. When you use the speaker level input, the gain control ranges from 0.8V and 16V.
Crossovers: The A, B, and SW sections also have independent crossover controls. The A and B channels have crossovers that can be configured for Low Pass, High Pass, or Off (Full Range). The rotary frequency controls let you set the crossover point between 40Hz and 500Hz. The SW channel has a low-pass filter with a variable crossover frequency between 40Hz and 500Hz. You can choose a crossover slope of 12dB/octave or 24dB/octave via a 2-way switch.
Remote Bass Boost Control: The included Remote Bass Boost control module lets you adjust the amount of bass (from the subwoofer channel) from the front of the vehicle. The Bass Boost circuit is centered at 50Hz, with a variable boost level of 0 to 18dB. Module dimensions: 1-3/4"W (2-5/8" w/mounting tabs) x 11/16"H x 2" (including knob).
Connections
Power: The power and ground connections are set screw terminals that will accommodate up to 4-gauge wire. The included 3mm Allen wrench is used to tighten and loosen the terminals. Pioneer recommends different power and ground wire gauges based on the length of the wire:
- 8-Gauge: up to 7' 3"
- 6-Gauge: up to 11' 10"
- 4-Gauge: up to 21'
Note: The amplifier has three 30A fuses installed. A 4-gauge amplifier wiring kit is recommended with a 90A fuse installed within 18" of the battery.
Remote Turn-on: The remote connection is a set screw terminal that will accommodate up to 8-gauge wire. The included 3mm Allen wrench is used to tighten and loosen the terminals.
Speaker Connections: The speaker output screw terminals for the A and B channels and the SW channel are of different sizes. The terminals for the A and B channels will accept up to 16-gauge speaker wire, while the terminals for the SW channel will accept up to 8-gauge wire. The set screws can be tightened/loosened with the included 3mm and 1.5mm Allen wrenches.
Signal Input: The amplifier features three pairs of stereo RCA inputs for Channels A, B, and SW. If no line level signal is available, use the included speaker level input harness, and splice the speaker wires from the source unit to the harness.

Amp was easy to install and sounds good. Fit well under passenger seat of my 2001 Subaru Outback. I haven't installed a subwoofer yet, but even without the sub, this amp has greatly improved the sound of my Sony head unit.
