Any problem bridging an amp into 8 ohms?

so you are saying it will not run at 2 ohm ???

hence my lack of understanding of the "total rms" rating

It will run two stereo. Four ohms bridged. It may be stable to two ohms bridges but why risk it when you dont need that much power.

900 whatever watts is for both channels running at 2 ohms. You will get a slightly different amount of power at 4 ohm mono but still close. And you should see mopre than half of that at 8 ohms bridged.

it says right there in the white circle i made that it does 958 total rms@ 2 ohm all channels combined.

so it just said it will do 958 at 2 ohm bridged.

so why won't it??

From my reading, the Punch 150 was basicly a 800.2 in a different case... The had exactly the same layout with different boards.

im just saying by the birth sheet it proves it can?

Im assuming thats both channels @ 2 ohms stereo combined... Should equal 4 ohm mono bridged.

and to think i had this all planned out a few minutes ago.. //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

Combined, you know like basic addition. Run each channel to a 2 ohm load and add the resultant power from each channel for (OMG!) combined power. The amp will not like a 2 ohm bridged load, but it should do plenty of power into 8 ohms and run relatively cool.

why not do it 2 ohm bridged mono?? it is on one sub

 

[patrick1202 10+ year member]

its w/e just saying it is whatever you wanna do

just showing your options

No it doesnt. You arent comprehending. 2 ohms all channels is not 2 ohms bridged.

1. Because the sub is only 500w RMS

2. Because Fosgate said the amp is only 4 Ohms stable Bridged

3. Cause i dont want to work my amp hard if i dont have too.

Thank you for your help everyone. BTW: These amps kick ***.. Almost 1000 Clean Watts for $200 and a pretty darn efficient for a Class A/B.

^^^^those ratings are confusing BTW....
958 total rms @ 2ohm.....what does this mean since it is a 2 channel? each channel does 459?

HAPPY DANCE
