Alpine KTA-450 4 channel class D amplifier..

50w RMS X 4 channels - 100w RMS X 4 channels dynamic peak power..look it up on YouTube to get what that's about...can be used independently or pairs nicely with alpine ilx w650 headunit..

Very nice amplifier..I used it to power four 6.5 & tweeter combo's rated @70w RMS by JBL and cooked a tweeter in 90 seconds .so what I'm trying to say is that this amp is powerful!! ..it can be bridged to 2 channels..

Look at pictures for specs. I've only used this amp for a month..after cooking my tweeter I had to buy new speakers so I took the opportunity to go way BIGGER...not saying this amp isn't powerful...just saying that I don't know when to quit...I upgraded my entire system to 2000w RMS..(still not done)..i'm guessing I would be what you'd call an "audiophile "..don't let it's compact size fool you..it's small because it's a class D amplifier..for those of you that are unfamiliar with different classes of amplifiers do a little research before you judge this amplifier by it's size.....class D amplifiers are all i run.
