AudioControl A600.4 Altitude Series 4-channel car amplifier (100 watts RMS x 4)

Flying high in first class

AudioControl's Altitude A600.4 four-channel amplifier's sleek anodized aluminum chassis protects the precision high-spec electronic components inside and provides high-temperature thermal dispersion through its stylish cooling fins. AudioControl designed this Altitude amplifier to power the music system in almost any vehicle — including some vehicles with stop-start electrical systems.

Performance

The A600.4 can power four speakers with 100 watts RMS each, so you'll hear and feel all the fine details of your music clearly when you're on the go. The amp can power separate tweeters and woofers in an active 2-way front stage stereo system, thanks to the adjustable onboard crossovers' wide frequency ranges. For a complete system application, you can use the amp to power two speakers and a sub — with up to 300 watts RMS for the subwoofer from bridged channels. An optional wired remote bass knob lets you control the sub level from your front seat when the amp's set up that way.

Volume-level security

The A600.4 has a Valet Mode feature that limits the amp's volume to 25% of its maximum when you engage it with your custom-installed switch (not included) — so parking lot attendants or your teenagers' friends can't damage your speakers by cranking up the volume too high when you're not around.
