4-channel versatility

Here’s why lots of people start building their systems with a 4-channel amp. You can run your front speakers with the front channels (A) on this Pioneer, then combine the rear channels (B) to drive a subwoofer. Then, when you’ve got enough cash to buy a second sub and a dedicated amp for your bass, you can use your 4-channel to run all your speakers. You can also put this versatile amp into 2-channel mode to send up to 190 watts RMS each to a couple of component speakers or subwoofers.

Practical features

The front channels sport variable high-and low-pass filters so you can better adjust the sound for critical front soundstaging or a finely-tuned bass. Switchable high- and low-pass filters on the rear channels help take the rumble away from full-range speakers or the sizzle away from a sub. A bass boost adds extra kick, if you want it. Speaker-level inputs allow you to add the GM-A6704 to a factory system. If your vehicle needs a sonic upgrade, this amp’s performance features and reasonable price make it a great choice.
