Bridging a 4 channel amp uses less current than the same amp ran in 2 ohm stereo (assuming same power output). bridging makes more power by doubling voltage (which quadruples power).

Further,

If the impedance load is the same, and the same power is attained, then voltage is the same and current is the same. A non-bridged 2 ch making the same power as a bridged 4ch into the same load will draw the same current as the same voltage.

Now, the efficiency is a different story, but the amps are different so no direct comparison is reasonable and it depends on the amps used. THD is another concern, but you generally have more available power when bridged so you are operating lower on the exponential THD curve.

Finally, you have more options with 4 channel amps, including active or bi-amp. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

We should compare two identically priced amps by the same manufacturer using the same topology... Ideas?

So a 4 channel amp is my best bet? Im a noob yall are kinda confusing me

A 4ch amplifier would be ideal, as you have more options as for more power in most cases, and configurations compared to a 2ch amplifier, for your money.IMO

sorry, Zako and I got into a more detailed discussion.

i recommend a 4 channel amp. but if you can find a good price on a nice high-power 2 channel, then that is ok too. Boston Acoustics has a line of high power 2 channel amps.

i will say that gain setting is more tricky with bridged 4ch, as is splitting the signal. you should use a DMM to set the gains on any bridged amp configuration.

Its alright and how about the Alpine MRX-F30 Its 300 rms 4 channel amp?
