how'd car audio get in there?
1% lizard tongue, 99% magic

thats what the termlab likes //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

car audio? where?

i dont know what m1005 your talking aboutheres my friends test sheet we have it wired at 2 ohms, and on the amp it display's a 14.4-14.3 idle voltage

I've actually tested the amp... those tests are under strict conditions on a RESISTIVE load.

Wire the amp to 2 ohms... watch impedence rise up to 4+, watch it put out under 700 watts.

Wired the amp to one ohm to get more juice out of it, only put out 850 watts. Had I not have multiplied by .707, it would be about on par with alpines rating... but x .707 = RMS //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Anyone that hooks thier subs up 2x thier RMS rated wattage would be paying attention to how the sub acted... and turn it down if need be...
Its not like they wire up the sub, full gain, and crank thier head unit...

lol, full gain, bass all the way up, sub level +20.... its typical! Especially with setups that aren't "loud".... people try to do as much as they can to get it louder, which is typcally turn everything up.

I've seen some sorry setups... the subs got to full volume on a *pioneer* mid level at volume 5... out of 60! Then they keep turning it up, and up, and up, and up.... and it just sounds nastier and nastier.

Sure, you SHOULD pay attention, but most don't.

Im kinda fishing around for some input.... I have learned lots about the ported Type R 12, but what about sealed? Anyone had one in a truck? How'd that sound, and were you putting 1000W to it, or just RMS rated power?
Can the Type-R 12 handle 1000W RMS as a daily LOUD driver?

What size sealed box for this kinda setup?

PS - I'm talking about the NEW Type-R 12

itll sound like shit and btw i hate that alpine amp.

car audio? where?

I saw one last week... or it could have been a home theatre on wheels //content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif

lmfao, take it from someone who had em in a sealed box.... Should make a vid with your sealed box too... haha watch it pull a 132 at 55hz //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

The R lasted all of 5 minutes in a sealed box, this includes install time, in my car. Why it hates being sealed so much, I dont know...

umm i dont think it can break a 130 sealed w/ my amp....

hehe you might be right... man do they **** sealed.

BUt, if i had to guess.. 132-133 at 48-50hz.

i can guarantee it wont, they had to turn the gain about 80% up for them to get loud and very distorted.

hm, they were definitely in phase? Below a 130 with a pair of 12's is just miserable //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

yes it was horrible, with gains set appropriately they sounded worse then factory speakers did

Are you sure you dont have some kinda defective amp? I mean I have no idea how you can say the MRD-M1005 sucks... Ive read about 50 reviews of the thing that say they are top notch... just dont get it, I will see soon enuff...

When you take an amp in to be tested for TRUE REAL LIFE RMS output... what kind of test do I need to have done, is there a name or someway I can describe to the guy what to do if nessessary?

mark said what mine did he was the one that did it, its garbage, no one actually tests them they go off numbers alpine tells them and says its great.

exactly...

645 watts isn't far behind the bx1605's 750 wired to 1 ohm.... and its ahead of hte bx1500's 550... lol //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

So if you don't know the actual power output.... you would think the alpine KICKS ***!!! just as loud as the bx1605 (to the ear)!!!! But no... the 1605 just sucks //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

don't think its uncommon for an amp to not come NEAR rated power when run under "rec'd" specs... it *never* happens. To get 75% of rated power under rec'd specs would make one hell of an amp.

The only amp I've tested to do more than rated power at (or below) rec'd specs was my kicker dx700's.... they put out 818 watts each @ 2.4 ohms, at 12.5 volts! Birthsheet said 750 at 14.4 @ 2 ohms.

The worst amp so far has been the autotek mm4000.... wired to "2 ohm" it did a wopping 1600 watts, thats 2400 watts less than rated!

 

[SmokeyNChris 10+ year member]

Just because I heard a couple people say it doesnt do the 1000W RMS @ 2OHM I will take mine in for testing on tuesday/wednesday, and scan thier reports, see who's talkin shit, and see who isnt.
I beleive it does between 900-1000W, Ive had Alpine amps for a long time, and all have put out atleast thier rated wattage.

custel or whatever says 850W atleast, which would be more beleivable than 650W... but none the less, I still stick with the 900W +

Any betters?

well getting results will vary. you can take it to them and theyll tell you one thing in one setup then , in your setup it may be diffrent, unless its gonna be tested in the same vehicle, either way that amp is rated @ 700W i believe. and most amps dont do there rated power. and yeah by the way that amp doing 900-1000 peak may be in belief. but who cares about peak! you also have voltage dropouts, so might wanna consider that and all that other good stuff...peace
