Alright, thanks very much for all the help!

 

If you look at the birthsheet for an MTX amp, you will see the explanation right there.....the RMS ratings are at 12.5V, dynamic is at 14.4V.

I like the way they do it, the dynamic is closer to what you will get when you use it "real world" and the RMS gives you a fair value when comparing other amps to MTX products.....

IIRC they don't even bother with 'peak' power ratings which is a good thing....

HTH

 

That's what I thought. My first amp was an MTX RT2200X that had the birth sheet and all that jazz but that was about 10 years ago. I just can't make sense of the math. If the voltage increases by about 15% (from 12.5V to 14.4V) and ohm's/Joule's law says that if you double the voltage you will quadruple the power (P = Vsq'd/R). Therefore at 14.4V the RMS rating should be about 663 Watts. 800 Watts of dynamic power at 14.4V would seem to indicate the peak power, and now we might have more of a glimpse into the amplifiers capabilities, RMS (safely, all day long) output of +-663W and a peak output (maybe only safe in short busts) of 800W when connected to 14.4V.

After a quick bit of hunting around last night I found more info siding with dynamic being equal to peak than the other. And it made me second guess my initial thoughts. I think the OP is more correct to relate dynamic power with peak power.

 

Hey so it looks like I'm gonna have to use the clarion apx400.2 any more input about this amp. will it power these subs sufficiently and how should I wire them? Thanks a lot for the help.

 

Is the MTX no good?

 

yeah I was told I could use both but then found out the the MTX doesnt work..

 

That amp looks like 100W x 2 at 4ohms. I would look for something else. Here's how you should wire it if you do end up using it.



I have a JBL that I'm no longer using, it's about 6 months old. Don't know if you're interested though but it would be a great match. JBL GTO7001. 700W RMS @ 2ohms.

 

Sorry I should have specified, is there any way to run them at 2 ohms?
and pm me the details about the amp, I may be interested.

 

Yes no. Each sub is 4ohms so if you wire them in parallel you'll have a 2ohm resistance but now what do you connect it to. The best you could do then will be to connect them to only one of the channels and you get 200W from the one channel but that will be for 2 subs (100W each sub again)

If that amp is 2 x 100W @ 4ohms, 2 x 190W @ 2ohms, 1 x 380W @ 4ohms bridged. What I showed you will be the best you can do.

 

Oh ok all good, I think I'll just use the clarion for a little while because the subs are rated at 50-250rms. So it should be find until I get another amp right?
