Well im no fan of the Alpine amps either, at least the older ones, have no  experience with the newer ones. Eclipse amps are nice but are not as clean as the Diamonds. Check out the THD ratings on the various amps listed. Alpines are very dirty amps, esp that one, 1%thd, thats pretty sad. The Eclipses usually are about .1%, the Diamonds are .02 or .03%. Hell the US acoustics would be a better choice than the Alpine, they are about .5%, built solid, and about half the price.

Specs are good sometimes, however they don not tell you how an amplifier sounds, how loud it is going to play or what it's capabilities are. Put that spec sheet up to your ear and tell me how it sounds, because for those of you that believe in "specs" being the most important factor, it's time to do a lot more learning. I used to be the one who looked at the "specs" because it's what I was led to believe was the most important consideration, I was sure mistaken and it cost me a whole pile of $$$$$. This is  the main reason why I own two of my own stores today. Everybody hears differently, what can sound good to you might sound like a$$ to your friend. Are you aware that most subs play an average of 15% distortion along with the music your playing, and as such do you think that .1% or .02% or even 5% is going to make that drastic of a difference? Just a ponit made about how a spec can have nothing to do with what we hear. Amplifiers make amps, they are not called wattlifiers or thdlifiers for a reason.

my test sheet does not show efficiency.

and as for thd, , it is impossible for the human ear to hear the difference in distortion until it gets to the 5% mark, so never base the clarity of an amp on thd.  Pyramis amps have like .9%thd, but the sound like my toilet bowl after chilly day.

The alpine class d amps arent meant for speakers, there ment for subs, and they play the bass frequencies clearly at peak volumes.

if you are worried about distortion, then get a class a/b amp and draw 200 amps of current to get the same result you can from 50 amps on a class d  ( that was exaduration)  << i can never spell that word right haha.

"forbiddin" is right, so listen to him....

Thanks alpine guy, It's nice to hear praise from someone other than my regular customers. I've had to re-learn alot over the years and continue to do so everyday. Look at some of these posts and even veterans can get new information from them. BTW Alpine has had some damn nice gear over the years, my favorite is the original 7909 and the 3558 pure class A 4 channel amp, I actually won this amplifier in a contest back in the late 80's - early 90's.
