Bridge into 8 ohms?
#1
Ok, I know this is probably a stupid idea, but what would happen if i bridged my 4 HU channels to power two 8 ohm speakers? Will it even bridge (won't it have to invert the channels or something?)? Will it fry (my guess)? Also, i heard that many/most modern HU's are already pre-bridged (8 channels bridged to 4), is this true?
Don't tell me just to get an amp or whatever, i just wanna know if this will work .

won't work... any "high power" head unit is already bridged (so anything with a +,- wire for each speaker.. common ground head units could in theory be bridged but you'd have to find a way to invert say the rear channels to be able to bridge with the front... even in that case you wouldn't get as much power as a single "high power" head unit channel

isolation transformers have a 1:1 ratio
Regular transformers either step up or step down voltages.
I dont see why regular transformers would not work since transformers are close to 100% efficient.
With 2 transformers you wire them in parallel to the speaker , and connected to the speaker leads of each channel.
the same as you would a 2 way crossover with 2 wires in and 2 wires out.
On this page is an example of the 2 transformer principle enclosed in a single unit.

The downside of transformers is you loose some low end response because of the induction of the windings on the transformer.
