So basically mate its a 5 channel amp, and you will get 4x50w RMS out of all for channels, then the 5th channel will give you 200wRMS for a sub. All speakers must be 4 ohm for this mode.

The Rockford Fosgate Power 551X is 2x70wRMS at 4 ohms and 275wRMS bridged on the rear channels at 4 ohms, which is pretty close and as its Rockford its top quality stuff. Thats priced at £250.

Actually im not totally certain on that particular mode, as the amp states these RMS outputs:

70x4 @ 4 ohms
140x4 @ 2 ohms
275x2 @ 4 ohms


Ill look into it a little further.

Yes it is possible to run the rockford fosgate in 3 channel mode. Thats the closest ur gonna get mate!


Quite a pucker amp really, considering it myself now


4x 140wRMS at 2 ohms, mmmmm

4x 70wRMS at 4 ohms,

2x 70wRMS + 1x 275wRMS at 4 ohms, yummy OR LAST BUT NOT LEAST:

2x 140wRMS at 2 ohms and 1x275wRMS at 4 ohms!


For £250 i dont think thats beatable
