Lightning Audio

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Our take on the Lightning Audio LA-51000

by Buck Pomerantz

Lightning strikes again

Lightning Audio makes a great line of amplifiers that'll appeal to car audio fans everywhere. Their LA-51000 5-channel amplifier will hit your whole system with over 60 watts RMS going to each of your four speakers, plus up to 250 watts RMS going to a sub or two. This handsome amp packs its wallop using Class AB amp technology, for clean, distortion-free reproduction of your music. Want power for two high-performance component sets and a sub? You can hook up the LA-51000 in 3-channel mode and blast a couple of speakers with 200 watts RMS each and a subwoofer with 250 watts.

Precise control

The amp features separate high-pass filters for the front and rear channels, so even if you're running smaller speakers up front and some big 6"x9"s in back, you can make them all sound their best. You can use the variable low-pass and subsonic filters on the subwoofer channel to clarify the bass to perfection, then crank up the bass boost when you want to add some punch to the proceedings.
