Default Bridged ohm load

If I wire a 4 ohm speaker bridged to an amp does the amp still see 4 ohm? I know if I parallel wire them the amp will see a 2 ohm load. Just can't find a clear answer on a straight bridged wiring. Amp I would be using is 4 ohm bridged stable (JL XD400/4v2).

Yes with a single 4ohm speaker bridged across 2 channels, the amp will see a 4ohm load.

Thanks. That's what I thought, just needed some reassurance.

Z,
I would still ohm out the speaker in question. even though the sticker says 4 ohm. Some manufactures are not as strict as others.

the act of bridging an amplifier is the combining the aspects of 2 channels into one channel. +from channel 1 and - from channel 2, in order to get more power, the amplifier's stability should be listed in the spec/instruction sheet and doesn't really change and should be be safe as long as your load is = to or a higher impedeance than the spec. if the amp is stable @ 4ohms, it's ok to put a 6 or 8 ohm load to it (lesser output) but not a 2 or 3 ohm load.
the wiring of speakers either in series or parallel will change the ohm load that the amp will see,,2 4ohm speakers in series = 8ohm load, 2 4 ohm speakers in parallel= 2 ohm load. check out this link,

hope that helps.
