Blaupunkt VA4100...yes BLAUPUNKT!!!!!
Disregard the name...this is a quality amp. I would have never bought a blau product until I did some research. Quote from a fellow ca.com member regarding this line of Blau's amps:
1. Powers down when it gets hot, but does not turn off. Just lessens the output until it cools back off. Known as "Thermal Throttle".
From Blau's site: "Our Velocity amps keep right on blasting – thanks to our unique “thermal Throttle” circuit, when the heat goes up, the amp gain adjusts automatically to prevent overheating from happening in the first place."
2. Has ground loop switches on the bottom. If you have a car that induces noise you can turn this on to kill alt whine, if not then you can leave it off. Known as "Hush Circuitry".
In my situation all I needed was power. I have my processor to do everything else (x-overs in this case). For the money, I feel these are great amps. I think they can be bought for $160 online, though I paid $140 shipped for mine. Also doesn't cause anymore dimming than my previous amp did, but puts out 2.5x the power @ the same impedence. This really brought my Rainbows up to speed, and I have much more clarity and refined sound (especially in the 200-2400hz range).
Manufacturer's Specs:Channels 4/3/2Also comes with a "cover" to hide the terminals:
Unbridged Power (Wrms) 4 x 100
Bridged Power (Wrms) 2 x 300
Load stability (min./unbridged) unbridged 2 ohms @ 4 x 150 W / bridged 4 ohms @ 2 x 300 W
S/N Ratio: dBa @ 1W > 80
dBa @ Full Power > 100
Input Mode RCA
Input Gain Range (V rms) 0.3 – 8.0
Crossovers (cont. variable) HP/LP, 50 – 250
Dimensions (in) 2.4 x 11.8 x 19.3
To sum it up, GREAT amp for the money.
