That would depend on the preamp. Name it. A true preamp outputs a variable signal.

It's not clear from the manual what the state of the volume output is without the VCA. Most amps default to full ON and the preamp attentuates the signal with a volume control. Try it with a signal that fades in slowly so you can intervene if it gets too loud. If it's full ON a preamp will control its volume.

If it has a tape/aux imput/output yes!
All you need is to connect suitable cables between them.
If your computer has jack sockets and the amp RCA type, use the type shown below:

How many ohms is your sub? The SA 3 Amp can only handle speaker(s) 6 ohms and greater. A lot of subs, as I understand, are 2 and 4 ohms typically. If yours is 2 or 4 ohms, then that explains it. The speaker would be "straining" your amplifier and blowing it.

its alwaays better just to call bose their great when it comes to this

You cannot add other brand speakers to Bose systems. You must purchase the Bose second zone speaker amp and speakers.

tda 2040 are a cheap aschips

your media centre and sa-3 are from two different countries they work on radio wavs, if the amp and media centre are different they will never work sell the amp and buy one that is the same region code as your media centre
