James,
it looks like you placed two speakers in parallel. Was the second speaker essential as it is still only the one amplifier driving the second speaker?


They are both driving the sound. The speakers are 8 Ohm so best use them to get 4 Ohm.

I used these http://digitrains.co.uk/ecommerce/search/hb078s-high-bass-speaker-0.78%22-square.aspx

Does sound good though.
