I pulled up my 2011 figures for ya...between my 3 locations (one in particular does all the ghettorific cars usually with Alpine's entry level amps) we averaged 13+ cars per week, 626 in total, were open 48 weeks total per year, that recieved new audio equipment, last year alone I sold 17 MRP-M2000's, 164 MRX-M100's, 132 MRP-F30's, 41 MRX-V50's and 57 PDX-F6's, so yea 411 amps not counting other Alpine models or JL's or Audison's or Hertz's or ARC's which i do in considerably less volume. its easy to average an amp per day when each car usually has more than 1 amp, and I don't do head unit power, i leave that for Best Buy or sell an MRP-F30 for $175...

That link didn't work

 

It went from "I" to "we" in a hurry lol!

I'm not sure where you think the hate is my friend. Like I said, I've read about numerous problems with Alpine PDX amps. But maybe it was the first version as you pointed out. The link I provided shows what I was referring to but it doesn't work, oh well.

And like I said earlier, I'm VERY pleased with my Alpine MPR's in my Jeep and I haven't read any bad reviews about them.

I hope business stays great for you brother

 

I use I and we interchangibly, after all I own the company, but obviouslly i couldnt do all that work myself...i have been lucky through these tough times and thanks man, o i think i confused u with the dragonrage, my bad no hating here!

 

Ya'll arguing and bickering in my thread is completely REDICULUS. If you don't have a suggestion. Get out.

 

Okay, let's keep the personalities out of this and focus on the facts.

First, the statement that underpowered amps won't damage speakers (including subs) is inaccurate. Contrary to common myth, an underpowered amp will not damage speakers just because it doesn't produce enough power. If speakers were damaged by not getting enough power then you could never turn down the volume. Underpowered amps damage speakers only when they are cranked up to the point of causing distortion. On the other hand, overpowering seldom damages speakers unless they are driven to the point of mechanical damage due to over-extension of the coil beyond its physical limits (as with almost everything, there are some exceptions).

Thermal damage to speakers is often caused by clipping because the square wave signal does not provide sufficient movement of the speaker cone to generate enough cooling for the coil. This is the primary reason that the factory subs of a Monsoon system blow so frequently - the factory head unit puts out so much distortion at higher volumes that the speakers literally burn out (they certainly aren't being overpowered by the Monsoon amp). Overpowering a speaker with a clean signal (sine wave) is less likely to cause thermal damage because the speaker cone moves smoothly in and out creating air movement to cool the coil.

Coincidentally, more details on this subject are available on the same Basic Car Audio Electronics website quoted earlier. Just go down to page 29 entitled "Too Little Power".

So, to get back to the original subject, the OP should look for an amp that has at least enough power to satisfy his volume requirements. It's better to have an amp that is rated higher than the speakers than it is to have an underpowered amp that might be driven to distortion trying to achieve that volume level. In an ideal world, the amp and speakers would both be rated for higher levels than the user would ever attempt (e.g threshold of pain) so that the equipment would never be over-driven.

 

^^^^^ thank you

 

The Alpine MRP M500, is a good little amp, I installed one in my sons car years ago to power his one kicker 12" sub, and it still works great.

 

i have the alpine MRP M500 at 2 ohms and its awesome!
