Amplifier Ohm load, is this safe?=Help

[ak49 10+ year member]

So the amp im using does 550 rms @ 4 ohms/1 channel, the sub i have is a dvc 4 ohm sub, so i can either wire it for 2 ohms or 8 ohms, the question is can i wire it for 2 ohms and run it off the amp? or will this damage the amp? (idc if it hurts the sub much cus its a pos freebie anyways lol)

the amp is a crunch p1100.2

the amp has no 2ohm rating?

nope, well it has a 225rms@2ohm on 2 channels.

so it is a 2 channel and you want to bridge it...

do not bridge a 2 channel amp below its ratings.

you can run 4 ohm stereo or 8ohm bridged. 2ohm bridged will send that amp into protect

****, so basically for the 1 sub id have to do 8 ohms, and it would get no power?

it would still get power...

ya but barley anythign right? liek a few hundred rms @ best?

it will get over 1000 watts since each channel does 550. when you bridge an amp at 8 ohms, each channel will see 4 ohms. this is why you can bridge it at 2 ohms, each channel would see 1 ohm and your amp is not one ohm stable...

am i wrong. that was my understanding.......

550 bridged at 4ohm is what he said:fyi:

and the crunch p1100.2 is

Power @ 2 Ohm: 550W x 2

Power @ 4 Ohm: 225W x 2

Its going to be hard on that amp and may even put in protect. Lets say it runs at 2ohm bridged with no problems (at the time), the only way it will be hard on the sub is if you clip the amp for a long period of time or unless it a low powered sub then you will over power it.
