Question on this old MTX amp...

[rn240sx]

Ok, ive had this amp for yrs and ive never really asked this question...

Here is what the specs are...

SpecificationsRMS Power 12.5 VDC Input2 Ohm Load 180 w x 2 4 Ohm Load 90 w x 2 Bridged 4 Ohm Load 360 w Dynamic Power 14.4 VDC 2 Ohm Load 250 w x 2 4 Ohm Load 125 w x 2 Bridged 4 Ohm Load 500 w

I understand the rms power at 12.5 V is.... but then i see DYNAMIC POWER at 14.4V.... does that mean PEAK power at 14.4V..?? If im correct then that means my sub has NEVER seen 500 peak watts cause my alternator has never went above 13.5V at any time which means my sub is starving for power cause it handles 500 watts rms...

Am i getting this right..??

The dynamic power can be thought of as potential power. It's how much the amp can deliver in a very short period of time, with plenty of voltage and likely lots of distortion. Don't worry about that number, just worry about the RMS at 12.5v.

Your sub is not "starving for power". It's not like you're running constant sine waves at clipping...though if you were, youtube it!

What else would you like to know?

I don't think they are using "Dynamic" as "Peak". In unregulated power supplies, the power output will increase with higher voltage AND decrease with lower voltage.

I don't think they are using "Dynamic" as "Peak".

What's the difference?

im just amazed how complex mtx words this crap.... I mean seriously RMS pwr at 12.5V.... thats easy and simple to understandThen u got DYNAMIC pwr at 14.4V.... ok, most of us understand what 14.4V is, but what the heck did they use the DYNAMIC word..??

Does DYNAMIC mean peak power..??Does it mean rms power..??

Jeez, not all of us out here are amp guru's... I called mtx 3 times and got 3 different answers.

One rep said it was PEAK power at 14.4V.. 2nd rep said it was rms power at 14.4V..3rd rep didnt even know what dynamic meant cause it was not on his computer and he didnt know where i was getting it from. I tried to send him the link but i dont think he was even trying to look for it judging from his enthusiastic (im over-exagerating here btw) voice...

The point is, most vehicles will NOT see 14.4V at any given time, at least i have never seen it in any of my 6 previous vehicles which means i will not ever experience what mtx's dynamic power really is....

some people need to keep it simple

If you look at most amps manufacturers "peak" ratings, they are a full double to triple the actual 12.5V RMS rating. That is why I'm saying that MTX is not using "dynamic" as "peak" since the power increase is only printed as 30% or so. It is not out of the realm of possibilities to get 14.4V at the amplifier but it is certainly optimistic in most cars. For SOME regulated amps, there will be little output variance from 10.5-14.4V (depending upon brand, model, etc) so it is not as important to have 14.4V for full output. However, the closer to 14.4V you have at the amp, the less amperage the amp will pull, the cleaner the output will be, the more power output there will be, and the cooler that amp will run. The electrical system must be in good condition for the best performance from your electronics. As a consumer, you should only be looking at the 12.5V RMS output rating since it will be the most realistic.
