The Pioneer GM-D8604 Class FD 4-Channel Bridgeable car amplifier is an excellent purchase if you’re looking to step up your car audio by several notches, and this amp will certainly give you the punch you’re looking for in a nice compact design.


In general, you can expect this amplifier to send around 100 W RMS to every one of your speakers, so you’ll really notice the power that your current system is able to produce when you install this beast of an amplifier.

Efficient Class D Technology

While many amps like these are known to be power hogs, this one benefits from the efficient class D technology that keeps it running surprisingly cool, and the compact size means that you won’t have too much trouble when it comes to installation either.

It’s worth noting that you can incorporate this system into many different setups, both large and small, and its versatility is a large reason why many people choose this particular model from the well-respected Pioneer brand.

Final Thoughts

One of the best ways to run this system is to hook it up with a mono amp to drive your subs while using this to run your other speakers, but the amp can equally serve well in any other setup you choose.

Lastly, the Pioneer GM-D8604 comes with some useful features such as the variable high and low pass filter that give you some extra control over your playback, which makes this a very attractive amplifier.
