Rockville M-4 At .5 ohm (no joke)

Recommended Posts

I like the part where it's says professional peak limiter circuitry which guarantees distortion free music at all levels.

They Could not possibly make up a bigger lie than that.

Yeah i wondered about that too. Maybe a dyno test could show if the input signal gets reduced at a certian level of output?

The video of the amp dyno he tested at half ohm, dont remeber the numbers but just search rockville amp on this forum and u will find his post and videos of it on the dyno.

There are better and worse amps out there, alot of memebers gave me advise on better quality amps when i upgrade this year. For what i need now, this amp does well. Did u say u strapped them ? How well was that set up ? Im also running 2ga royal excelence welding cable. It works just fine for what this amp could pull.

Edit : spelling

No i havent strapped them yet. I was just running the single M-4 at .5 ohm.

I believe if u test at a higher frequency u will get a higher rating ? Big D did the dyno at 40 hz so even if they rated the amp at 1500 watts rms it still did it close at 40 hz.. i think certified (until distorion) it did 1283 watts and uncertified (until clipping) it did like 1534 watts @ 40hz on the dyno video

(Sorry i dont know how to quote correctly)

I think certified stops when it sees distortion and uncert is at clipping both at 1%. I think .8% is when it becomes audible.

They are both at 1% so i am not sure what the difference is. 1% is 1% right?
