enough power?

punch 200s specs: Per channel power 50 W X 2 @ 4 Ohms RMS 100 W X 2 @ 2 Ohms RMS 200 W X 1 @ 4 Ohms Bridged RMS Total power 400 Watts Peak/Max pushes 2 premier: 200 nominal 4ohms will this under drive it if i bridge and parallel? thinkin parallel get to 2ohms and the power will be at 400. is this right?

Read your manual and see if your amp can actually push a 2 ohm load in the bridged mode. From the above information you can not, if you do it will blow. I would run it in 4 ohm stereo mode, one channel to each speaker, or buy a second one and bridge both, run one to each speaker, this should give you the 4 ohm load and maximum power you are looking for. I did this with a pair of kenwood 600 watt amps and a pair of jbl 12's and it worked out pretty well and bumped, considering the I didn't spend over 5 bills on it.

thats what i thought. am just makin sure, my buddy tells me thatll push it.

im installin this for this other guy, but my buddy insist that the amp will push it. he said that rockford pushes more than it tells. i told him that it wont be stable at 2ohms. he also tell me that if rockford overheats it will shut down (i know it has thermal protection). what should i tell him. what are the consequences that will happen, so i can tell him.

find a Class D mono block stable down to 1 ohm. the you have all the power you need. run the rf on your mids and highs Big Dave

Rockford falls in with most other manufacturers where the mono stability of multi-channel amps is concerned. 2ohms Stereo and 4ohms Mono is the lowest you can go without either... 1) Shutting down the amp 2) Causing the amp to Clip, which can damage the amp and/or subs 3) Destroying the amps circuitry What your friend was referring to about Rockford amps "pushing more then they tell" has to do with Continuous Power Output (or RMS output), not the minimum impodence (ohm) stability. Most of the time RF amps will outperform their rated power specs, like a 500 watt amp may actually push 550+ watts. But the minimum stable ohm load does not change. If they say a minimum of 4ohms mono/bridged then they mean it! And yes, you will be underpowering the subs if you hook them up to that amp. The only safe ways to hook them up are either 1 sub per channel (50 x 2 @ 4ohms), or hook both subs up to only 1 channel (not bridged, just hooking both subs up to only 1 channel), left or right it doesn't matter (100 x 2 @ 2ohms). Either way you'll only get 50 watts per sub. So that's underpowerring them by 150 watts a piece. What you want is either... A) 1 Class AB 2-channel amp rated: 200 x 2 @ 4ohms B) 2 Class AB 2-channel amps rated: 200 x 1 @ 4ohms mono/bridged C) 1 Class AB 4-channel amp rated: 200 x 2 @ 4ohms mono/bridged D) 1 Class D Mono amp rated: 400 x 1 @ 2ohms Always rate based on the RMS rating of the amp and the correct ohm load. Don't get fooled by the "Max Power" rating. It's bullsh*t, and you'll never get it. Most of the time the max power rating is a millisecond before the amp melts itself into a molten pile of steaming metal, and they have to use an ungodly amount of amperage to even get close to it.Squirrel
