Time for another Flea Market amp test. Today we will look at the American Legacy LA3090D, the largest monoblock from Legacy's 2005 amplifier lineup. Although the amp states "3000W" on the plexi panel, the manual mentions 1200W RMS or 3000W max. It is not unusual for amps like this to have bloated ratings and usually they don't even state RMS numbers. Not sure why, but this amp just looks cool to me and it would be really cool if the amp could perform as advertised.

The LA3090D sold for $140 back in 2005 although the "retail" price was over $300. Yeah, right, that's the price they would show at the local Flea Market before slashing the price to over 50% off...today only! I must say if I saw an amp like this I may have been swayed to pick one up. Could it possibly be a legit flea market amp?


Ratings as shown in the manual:
4 ohms - 400 watts RMS
2 ohms - 800 watts RMS
1.3 ohms - 1200 watts RMS
1 ohm - 3000 watts "MAX"


Other than JL Audio and maybe MMATS amps, I don't recall companies giving ratings at 1.3 ohms. It was my thoughts this amp couldn't really handle 1 ohm. Well, it does, kinda. You'll see what I mean in the video.
