mine was a budget system under $1000CAD lol :P

curretly i am pumping out 730W RMS

87.5W RMS / Speaker (x4) = 350W RMS
190W RMS / Sub (x2) = 380W RMS

pretty good considering it came from the stock 100W Peak (25W RMS?) system

mazdaspeedwest

i run about 800-900w RMS

600 to the subs alone

but IMO, power is nothing with out the quality behind it.

i have 65x4rms plus 800rms@2ohm under rated watts to my sub. I will soon drop the amp to 1ohm and pump 1200+rms to my new sub hehe so ill have around 1400-1500 rms if my car can provide it lol maybe for short times.

Wonder how many of these replies are accurate...

Robdoggz

well im just letting you know the rated power my amps do at 12.2v so with some votage drop im still getting very close to if not more than 1000rms but only when im pounding away but as far as daily driving im probably pushing maybe 4-600 at regular volumes.

KYREDP5

Simply because I don't trust the mfr. ratings, and I'm too damn lazy to get the ol' multimeter out, and my old EET books out for the formula to figure wattage.

KYREDP5

I never said the amps were pushing that. It's just eaiser and shorter to put what the amps say on the front rather than the model number. And I don't have a DC power source at home. (wish I did). So bench testing is out of the question.

This was very aggrivating guys! It just snowed here today, and is about 15 freakin degrees. Now with all respects to our Canadain friends on the board, here in Oklahoma that is cold, and the 8 inchs is enough to make moving around a drag.
BUT- I go slogging into my shop today, and break out the brax, and got the numbers off the computer generated performance sheets that come with each one. The three X1000 produced 105, 105 and 105.5 each per channel, with .0025 THD. The SPL amp produces 312 in mono at .002THD. Total of shy of a 1000, sorry.
If I had hooked one up and benched today, I would have expected to exceed these number marginally thanks to the cold (although I keep the shop a little heated all winter).
Every amp off the line will have varations thank to mass production except individually built units, and then as you can see here, there are variations. (Somehow I don't see the Germans not meeting thier minimum marks though!!) Some amps will provide a computer generated test chart showing actual output, but even then the true readings may vary due to enviorment. Lastly the speakers themselves produce very unlinear loads on a amp, different notes, tones, harmonics, the lenght of wire runs themselves, input voltage, will all result in different ohmages at the amp. Some of my favorite speakers out there don't actully read 4 ohms when you test them, they might show more like 3.85. I am always big on trying to find amps that will actually hack it down to ONE ohm if I am going for a two ohm load.
I guess I am trying to say that even with the bench full of testing equipment I have, I can't get replicated results all of the time, and my mentors and teachers in the field couldn't have been that wacked out when they taught me how to use the hardware!
Finally in a car itself, you really do have to get right to the speaker terminals themselves and measure with a musical load to see what you might really be running, on a good day, with decent source materal!
Many of my friends who do serious SPL love the unregulated amps for the extra bump you can get if you run a full 14 to 15 volts, but for daily use regulated amps have always seemed much much more logical. In traffic, with lower volumes, they will at least keep producing at a level amount.
KYREDP5- your distrust is sound, there are no true standards in audio performance measurement, no governing body. I would hope the reputable manufacturers would not lie too much in thier numbers though- it would frankly be bad for business once it was to come out in the competition circut and the trade rags. The trick is to see what distortion numbers are measured at.
No one will give you the true measure of items like the tonal load used to test (unless a hand built Godzilla), but the numbers are probably the best we all have to go by. In my years of testing amps, I only found a dozen or so that when I put them on a constant (somemight say friendly to results) load did I find were under the manufactures suggested performance specificatons.
I don't see anyone stepping up out of the kindness of thier hearts and becoming a international regulatory body on car audio specs, and I don't see the industry seeing any need to pay for it on it's own( afterall we all do know they are just a bunch of crazy hop heads, or corporate greed mongers, right? )
So we have to trust what they tell us for numbers, unless it is a cool flea market brand! I use to have a friend in town who when he either replaced a dead cheapo with a nicer amp, or told the cheapo amps owner it was not worth fixing, would then give the dead amp to me! They were really fun to take to the gun range! And who said they served no useful purpose?
By the way, the trip to the shop was cool, Allison and I built a snow cat, and snow dog, and had a good time throwing snow at one another until we froze! Right now the curry is cooking, hopefully we will warm up, and go to bed early!
Happy Amping!

hey, I'm running a single Infinity 1020W ~250W RMS, but only feeding it ~100W RMS. It pounds like a mada ***** !!!

EZ as 123

wow
those magnets are HUGE.

What kind of box are you going to be using ?

eggynatey

Oh yeah? Well I've got a Basslink! LOL! It actually sounds pretty good for us who just want a little extra kick.
My wattage: Alpine HU-20x4rms(bridged to the rear), Alpine amp-50x4rms(bridged to the front), Infinity Basslink-200rms= 480 big ones! woooh!
Watch the quarters jump!!
(BTW, that third sub is a MONSTER!)

geez, i still haven't upgraded my amp. 500 to my subs, 500 to my spkrs. even at 500w, my subs POUND. too much for a little p5 tho... didn't plan my system very well, got too caught up in the spending

eggynatey

---Your system looks nice to me... T.V.s and ****?...you're Pimpin' compared to my little stereo.

onehawaiian

thanks for checking out my system, but i wasn't thinking when the guy who i bought my fusion stuff from offered me two 12" jonah lomu's for an incredible price. but putting two 12" drivers built for spl in the back of a hatch? took me forever to get my frontstage just right. and my sub amp gains are down, as is the sub channel on my eq, and it still pounds!

next system's gonna be cherry cause it's gonna be planned out right.
