Frequencies wernt the concern here, and iv never seen a monoblock amplifier that goes into frequencies above 250hz anyway...nevertheless power efficiency was the related concern, as for power being free in a car, true.. but the thing to remember is you are limited to the amount of amperage your charging system can put out, if your using a class a/b amplifier for whatever application just know that style of power supply switching is normally at best 50% efficient, which is why you always see in gigantic product packaging 1000WATTS!!! followed by a size 8 font of 500wrms, also a multi channel amp being used for subwoofers is putting more strain on the amp in turn causing more heat due to a heavier load, and being a class a/b will turn itself off to protect from overheating much more easily then a class d style amplifier, im sure most everyone has seen that before.

so without turning this into a flamewar or an army of misdirection just a good tip and relative way to think about it class a/b 50% efficient and class d 80% efficient at best, at least for the majority of the products we have or can afford.

most all Mono amps today are just internally bridged stereo amps. no real difference there.
like talking to a brick wall on this forum sometimes.

also a multi channel amp being used for subwoofers is putting more strain on the amp in turn causing more heat due to a heavier load, and being a class a/b will turn itself off to protect from overheating much more easily then a class d style amplifier, im sure most everyone has seen that before.
you shouldn't be driving a load that makes it over heat anyways. not trying to argue, just trying to keep misinformation from spreading. a properly sized amp on a proper load will not overheat. no matter if a/b or d class.

I whole heartedly agree that a class d is more efficient. Would you trade your Ranger in for a Prius? just because its smaller and more efficient. even though it saves gas your still downgrading to a weaker less useful vehicle. thats the same concept with cheap Class D amps ... they are not always better. there are very few well made class d amps out these days.

my current set up is metering well for being inexpensive. its also very very clean and tight. I have been through the reg cab battle for a while. im running 2 re audio 8s and an autotek amp. no problems here!

He said 1000 watt max. I doubt he constantly pushing anything near that.

Kicker cvr are always good. I have a cvr 10 in me x cab for years and I never even ran it to its full capacity and it was great for me. If I were to do a new system I would go for low profile subs especially for a single cab.
