Alpine 1507

[fuzzai 10+ year member]

Hey Guys, i was wondering, if anyone has alot of experience with this amp? I currently own one, and as per Alpines "guidlines" i guess, the amp should only be ran at 4ohms bridged.....

now my question is, how efficient would it be running at 3ohms pushing a 10w7?

Obviously yes i can hook it up to 3ohms, //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif but should i? are the amps that picky?

Thanks

and besides the ohm load is going to fluctuate a bit as your sub moves and when you put it in the box. Usually it goes up, so I would say you're perfectly safe.

dude how much does one of these amps go for in US? anyone ever made a test to see it's real wattage?

im curious

The amp when tested from Alpine is tested at 12volts, at 4ohms per channel.

It is to put out 150wrms x 2 at 12volts. so at 14.4volts its to put out 450wrms x 2 at 2ohm i think and 900wrms x 1 at 4ohms...

mine was tested at 193wmrs x 2 at 2 ohms at 12 volts. so im sure it puts out a little over 1000wmrs....its a big amp, thats the only problem //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

are there any other alternatives to it? heh it seems kinda big and heavy lol... i'm sure there are many other alternatives for the price...

but it must be a very good amp, because Alpine amps usually keep a clean signal after the amplification, unlike some other brands hehe... but it's not all that necessary for subwoofers, unless we're talking about amps that send too much distortion or has that unpleasant bass you know...

i noticed alpine amps, fosgate etc have a MUCH better bass for my ears than many other brands... i heard some amps that offer much more wattage per penny.... they hit harder, but a "clean" amplifier gives you that will to increase the volume because it's bass is much better for your ears, and i believe that coutns much more than just decibels...

well what do you heavy spl guys use to amplify your subs in US usually?

this alpine amp is getting old, and i like that... prices drop a lot heh.. i may get an used one soon, it must be kickass from what i've been reading... any personal experiences from any user here to share?
