Nope, have you tried it on cd mode to eliminate it from the radio reception

Try a 9v battery across the speaker terminals briefly do you get any sound.

Check the speaker terminals/speaker wire isn't touching any part of the chassis. Having just installed it, I'd be looking behind the stereo first. There is a way to test the speakers for shorts if you can't find anything wrong behind the stereo

I assume you definitely have the correct wires connected! Pink/Purple = Front left//Blue/Green = Front right etc

Some jap import cars have an external amplifier mounted between the factory stereo and the speakers. Removing the factory stereo removes the power supply for the amp. The external amp is unnecessary anyway now that you have an amp built into whatever headunit you bought. Grab a spare speaker or remove one from a door and wire it direct to the new headunit bypassing the factory wiring to check if it solves the problem.

Don't do this while it's wired up to the headunit.

Good point, I just assumed one would disconnect it first.

carkitter : I considered a factory amp too. but I don't think the Surf came with one (its been a few years so my memory may not be serving me correctly) But if the speakers and power wires were tested, it will be obvious there is an amp due to not being able to find speakers. Plus the wiring colours will be totally different to 'normal' Toyota stereo colours.
