I'm not specifically familiar with that model but I'm pretty sure the"CUR" is indicating under current or not enough current. what's happening is your amp is under load and doesn't have enough power so it shuts down rather than smoke. I would suggest you run heavier cable from the battery to the amp and add a giant cap so that when the amp surges the cap will compensate for the sudden draw. This is not a cheap fix but if you install heavy duty power cable and a quality giant capacitor (2 farad) you will be able to push the amp until your speakers catch fire and your amp will be fine.

Just want to know what speaker wattage matches my v12 mrv f705 85 rms x4 channel amplifier?


Use speakers that will handle 85 RMS continuous or higher wattage. I have 200 watt Rockford 6.5s on a 75 watt amp. They sound great with plenty of headroom if I go to a bigger amp.

You are probably running the ohms too low for the amp and its drawing too much current. Consult your amp manual for proper load level capacity and you can wire it accordingly. More then likely its only 4ohm stable bridged and your running it at 2 or less depending on if your subs have single or dual voice coils. Try connecting one pos speaker terminal to the other speaker neg then run the left ofer pos on one speaker and the the left over neg directly to the amp (series) I will raise the ohms (amp makes less power) but should not cut off unless the subs ohm are still to low, if this is the case you need a sub with a higher ohm rating or an amp wiht a lower rating...
