Can you bridge a Head Unit?

The rear channels on pioneers cannot be bridged.

Turning on rear speaker subwoofer in the menu simply applies a low pass filter and a mono signal to the rear speakers. They are still 4 ohm stable as a pair, so you could run two 4ohm subs at 22w each, or one dual 4ohm sub at 44w total.

They ARE 2 ohm stable if you only use one channel. Using two, its power supply will probably run out of current and something will fail. Thats why they say to use only one channel at 2 ohms.

Not bridgeable by any means.

The reason is that modern head units (mid90's and up) already have bridged outputs. Think of a HU as having a STK IC amp with 8 channels, bridged to 4. That is how they get the power out of something the size of a credit card.

Yo I appreciate all the help my negros, so with 2 ohm I can do it without blowing up my face

Aside from the few exceptions noted, you can't bridge HU speaker outputs because they're already bridged internally. That's how they're able to get 22 W from a 14V power source. All 4 channels are identical. If you connect between L & Rt channels you get a mono output at normal HU power. Connect between F & Rr channels and you lose the ability to fade but don't get any more power. No smoke will escape.
