I helped a friend of mine move the other day and he gave me some car stereo stuff he had stored for years and decided he was never going to use.

Alpine cassette deck with CD changer, massive ported box with 12"sub, PPI crossover, and....

A Soundstream Rubicon "Lil Wonder". It's a 2ch amp with a 25A fuse.

However, I can't find any specs for the thing. I googled the amp and found a manual.

Scroll to the bottom to look at the specs and see things like "A lot!" "Huge" "you can't hear it"

So does anyone remember a bench test in a car mag or something?

I opened it up and compared it to a 4ch Alpine I have sitting on my work bench that is rated at 100X2 bridged into 4 ohms.

Both amps have single 25A fuses and a total of 8 output transistors. But the output transistors in the SS are smaller than those found in the Alpine. Because they are sandwiched between the PCB and the heat sink, I can't get a part number off them without getting messy.

The SS amp looks better built than the Alpine overall, but the power supply looks less substantial.

So...how much power and what's the minimum impedance / max load?

 

I looked at the specs on the pdf manual. Classic!

Click on some of the forums that pop up on google. Might give you a better idea of what you have. Also click on images for google and see if you can match your amp to the image and search from there.

 

as a rule of thumb you can use the Power Equation of Power=Current x Voltage. This will get you close to RMS power. So, 12.6V x 25A = 315 RMS Watts. Plus the amp is only rated to handle 8 gauge power wire. I would expect 200 to 250 RMS from this amp at its lowest impedance.

looks like the lowest impedance will be 4ohm bridged or 2ohm per channel.

good luck, sound stream has been known for strong amps.

edit....I just looked up the new lil wonder amps and the one with a single 30A fuse is 260RMS Watts @ 4ohms bridged. so the 200 to 250 i stated previously is probably close.
