ok dont have the wallet for those amps... although ive seen a Zapco Amp power 2 L7's to maxiumum wattage ... but i need something more in the 200-300 dollar price range
I've heard that the Hifonic amps don't have that great of reliability. I love my kicker amp, and ask most people. The Kickers are very well built, when used properly, they hold up well. The KX450.2 should do nicely. It has a little more than you'll NEED per say, but it will do well. In your budget too.
If you're not a fan of Kicker amps(which i was skeptical before I bought mine(its great)). Then I'd say go with the MTX thunder502. These are both nice amps and within your budget.
Oh... if forgot, if you're looking to power TWO SETS of perfects, not just 2 speakers, then I'd go with the KX800.4. It'll push 100 RMS to each of your 4 speakers.
