RE: alpine mrp-m350 enough for...
was that a refurb.?
that is cheap, alpines amps are nice, but seem pretty expensive when compared to others.
dont get me wrong, I love my 501, but I payed almost $1 per watt retail. worth it? maybe.....if you really like fine tuning your system, the digi's were great.

well now thats 450rms to a 500 rms sub.

RE: alpine mrp-m350 enough for...
I was talking about the mrp-m450.
and actually, its only rated for 400rms at 2 ohms.
and i wouldnt call an extra 200 watts pretty over rated.
my sundown will do over 2200rms at .35 ohms.....thats pretty underrated my friend.

*copy and pasted from Jacobs board*[/align][/align]results from the sundowns...
Test Vehicle.. mine.. 05 aveo..
RMS clamp and dmm, as seen in the 12" test session..
This testing includes recent results, and not so recent..
woofers used.. 2 Mags (1.9 dcr per coil), 2 FI Q 12's (1.4 dcr per coil)
either used 1 sub or both of the pair for loads..
pure 60hz sine was used to tested.. just under audible clipping
1 amp, single 1000ca everstart maxx, factory alt
4 ohm nominal = 518 watts @ 88% efficiency (voltage fell from 14.3v, to 14.0v)
2 ohm nominal = 948 watts @ 85% efficiency (voltage fell from 14.3v, to 13.6v)
1 ohm nominal = 1510 watts @ 78% efficiency (voltage fell from 14.3v, to 12.4 volts
.5 ohm nominal = 1615 watts @ 72% efficiency (voltage fell from 14.3v, to 11.8v)
.35 ohm nominal = 1748 watts @ 67% efficiency (voltage fell from 14.3v, to 11.4v)
amplifier was protection happy @ .35 with tones, and some music.
IMO.. one 1500d should be limited to 1 ohm nominal use in factory electrical systems.. for the sake of the car.. not the amp
now... to have fun with some juice..
1 amp, single 1000ca everstart maxx, 1 Eagle Picher 12a5000, factory alt
4 ohm nominal = 520 watts @ 88% efficiency (voltage fell from 14.3v, to 14.1v)
2 ohm nominal = 960 watts @ 84% efficiency (voltage fell from 14.3v, to 13.7v)
1 ohm nominal = 1635 watts @ 75% efficiency (voltage fell from 14.3v, to 12.8 volts
.5 ohm nominal = 1890 watts @ 71% efficiency (voltage fell from 14.3v, to 12.8v)
.35 ohm nominal = 2245 watts @ 65% efficiency (voltage fell from 14.3v, to 12.8v)
amplifier did fine @ .35 with tones and music with the added battery
2 amps strapped, with both batteries (for the sake of not typing it over and over... voltage drops from 14.3v, to 12.8 the entire test... lol
4 ohm strapped = 1900 watts @ 82% efficiency
2 ohm strapped = 3150 watts @ 72% efficiency
1 ohm strapped = 3740 watts @ 68% efficiency
.5 ohm strapped = 4425 watts @ 65% efficiency
.35 ohm strapped = 5415 watts @ 62% efficiency
amps would only tolerate a VERY short burp @ .35.. [/align]

i kinda thought underrated (in pretty much any context) meant: better than they say.
in the world of amps and woofers i take it to mean: more power than they say

RE: alpine mrp-m350 enough for...
I guess you could look at it that way.....
But some companies over rate by 50 watts, others by.....alot more.
there are lots of variables when testing amps.

RE: alpine mrp-m350 enough for...
So is the mrp-m450 enough?
cause theres one on ebay but it doesnt include a manual, 2 end caps, and hi-level input harness
what are all those...besides the manual
and can i get them easily for cheap?
if the amp is good enough then thats great.
im not looking to completely fine tune it as this is my first car and i plan to purchase a different one later on and then put all my time and effort into it
now im looking for something that will get the job done
and if its the 450 and the type r GREAT

RE: alpine mrp-m350 enough for...
they will work fine together. make sure you wire that amp at a 2 ohm load.
