From value and sound quality to ease of installation and lack of unnecessary frills, the Pioneer GM-D9705 is one of the best 5-channel Class D amplifier that can run an entire mobile speaker system.


  • Delivers big sound without sacrificing space
  • Offers installation flexibility for a variety of applications
  • Packs a major punch with 2,000 watts max power onboard


  • Runs a bit hot
  • Down-angled inputs can pose installation challenges
  • Documentation in box is minimal


It’s true that there are a whole lot of amplifiers out there on the market, but only a few we’ve come across that are actually worth the money the manufacturer is asking for them. The Pioneer GM-D9705 is one of those amps.

This model is part of Pioneer’s line of midrange amp models in the classic GM series, boasting Class D certification (which equates to utilizing a modern high-efficiency design based on high-speed switching amplifier technology).

What this basically boils down to is that the Pioneer amp delivers higher power efficiency (less wasted power being dispelled as heat) and cooler operating in high power output conditions.

Like other five-channel amps, the GM-D9705 offers flexible installation possibilities, allowing you to drive rear speakers even if you have only one pair of RCA outputs, as there is a two/four-channel input switch provided.

Power Configurations

Several configurations are possible with the Pioneer GM-D9705:

  • Four main channels (full-range front and rear) plus one subwoofer output (bass only)
  • Three main channels (two standards plus one bridged) plus one subwoofer
  • Two main channels (two bridged for extra power) plus one subwoofer

Signal Input Options

As we already mentioned, the Pioneer is extremely flexible, but this doesn’t end at its number of channels: It’s great for factory systems, as well, as the handy four-channel speaker level connection that’s included makes it simple to connect this car amp to stock head units.

The product comes packed with an owner’s manual and warranty info, bass remote knob assembly and cable (plus mounting screws), amp mounting screws (black, half-inch), speaker, and power terminal Allen (hex) wrenches and front/rear speaker level input harness.


The Pioneer GM-D9605 was Our Pick for recommended five-channel amps, so you can rest assured knowing the 9705 will follow in its footsteps in terms of power, quality, efficiency, and longevity.

This is a very compact amp for its power class, with controls that are well laid-out and which work well in our experience, and wiring terminals that are a bit out of the ordinary in terms of placement but are of very high quality, too.
