AMP!!!! Double output linkage.

Dannyball · 28th May 2004, 03:54 PM

Hi all.

I have got one of these:

http://www.bkelec.com/new/HiFi/Drive...bsbl12-100.htm

and i am going to power it with one of these: (it's the 621)

http://www.st-and.demon.co.uk/Audio/armstrong.html

Since the upove has only got a 40w output i am looking at taking both the outputs from the amp and joining them somehow to power the driver. But how am i going to do this? Can you help?

I only really have knowledge of standard grade physics so please make the explinations simple, this is the first sub i've ever built.

Thanks for any help

Hi,
You can not join the two outputs together!!!!!!!!!!!!!!

However you can bridge your amp (one input to the amp normal and the other inverted) which would give you 80 Watts.

bridge???

How does that work.

Is there a simple diagram of this setup?

^^Sorry if that was a stupid question but i got to learn about this speaker/amp stuff somehow
