I've seen people say that "Old Pioneers" could be bridged. Are there any current models? Is anyone on the site doing this?

I really don't want to do an external amp, so this would be a great option for me if it is not ridiculously expensive.

Any info out there?

 

Generally, NO. Unless the manuals that came with your head unit
specifically state that your head unit can be bridged, then do NOT
attempt it - this could destroy the head unit's internal amplifier, and
possibly void your warranty.
