well in any case, your subs will most likely stay in a working state. Rockford is notorious for over rating there amplifiers. The thermal will def not kick in and save your amp if the impeadence (ohms) is too low. the only way to connect two dual voice coil subs to a stereo amp (2 channel) is by a series parallel combination. You need to series the two voice coils together on the subs and then parallel them on the amp(bridge).

I would disagree that RF is notorious for over-rating their amplifiers. Every one that I have tested puts out close to its RMS power and then some depending on model.

I have found this to be somewhat true in their higher end amplifiers. I've just never liked the sound that that ive gotten from them as i do from other companies. Their FET's inside the amp are too small. Well I'm mainly talking about their stuff from a couple of years ago. I'm liking what i see from them now but am still dissappointed in their overall performance.

alot of amps wont even play if the ohm load is too low.....will just kick into protect........but if it did play at 2 ohms it would get hot fast and therefore kick into thermal/protect. Like hillbilly said....most of rockfords amps are slightly under rated.....at least the ones i saw, thats including the punch line.

So because my amp is only 4 ohm stable and my subs are wired at 2ohms, if I unbridge my subs and just wired them regualry everything will be wired how it should??

No, because your subs are still wired at 2 ohms, and the amp can only handle 4 ohms...

What you need to do on your subs, to make the amp happier, is wire the voice coils in series, then the subs in parallel.

Or buy a 2 ohm stable amp (preferably mono for subs...)

I really think that you should take your system to a local installer and let them install it for you. That way, nothing gets messed up and you dont hurt your subs or your amp. Im not trying to be mean, just honest.
