autotek 400x "the street machine"

[akheathen Premium Member]

ok, so i've been searching both the forum, and web, and cannot find any info on it. i'm sure there are some of you out there that have experience, or even still own one. it has an autotek fat900 board in it, and the nudies suggest that it can support a lot more than 400, but idk at what ratings, and how far it can be pushed yet. i know it works, but i'm going to go through and check for any dry connections and such before putting any load on it. it's from 96, btw.....

Autotek Street Machine, very rare but powerful amp. built like tank, sound like beast.

200x -

Output Power at 12V:

2 x 100W @ 4 ohms (0.015% THD)

2 x 300W @ 2 ohms (0.15% THD)

1 x 200W @ 8 ohms bridged

1 x 600W @ 4 ohms bridged

S/N Ratio: 102dB

400x -

Output Power at 12V:

2 x 200W @ 4 ohms (0.015% THD)

2 x 600W @ 2 ohms (0.15% THD)

1 x 400W @ 8 ohms bridged

1 x 1200W @ 4 ohms bridged

At 14.4v, it's about 20% more power, and it's heavily under-rated, actual output is more than double

^ specs are very wrong i have ran a few of those amps including the 601x and 200x.

they are made in korea and underated but not that much.

100x2 @ 4ohm 200x2 @2ohm or 400x1 @4ohm mono. they are underated some and will run 1ohm stereo and 2ohm mono no problem.

I have aquired an autotek 201x. on the amp body it says 200 watts, is that true rms or max? also, can anyone tell me how to bridge it to get more power? Just want to run one single 10" sub from it and the sub is 4 ohms..? also, when bridged, anyone know the true rms wattage on this amp? cant find any real info on it.

thanks

no bridging it is a class a/b mono block. 200rms @2ohm, 270rms @ 1.33ohm
