elevation audio products any good?

I have several sets of the concert series components and love them.  We had three ten inch comp subs in my brothers truck with a mtx 801d and they slammed.  And I have two of the 2000.1's and love them too.  I would say they make good stuff. 

One of the 2000.1's I have running two fifteen's in a bronco and it is ridiculous.  No distortion and the amp has ton's of headroom.  I have the gain turned almost all the way down, and it is putting out tons of power. 

I understand that.  I had the amp set properly and had to back off a little bit because it was putting out too much power for the subs.  The amps start at 5v, my preouts are roughly 3v.  The amp is turned down closer to 5v.  Therefore I have the gain turned almost  all the way down. 

But thanks for your replies, they were very informative.  Especially considering you offered no information at all to the original post.   

oh come on now thats not needed.

i did not anser your main qestion because i dont have any thing good to say about that brand i also have nothen bad to say ether. i have never heard of them. to tell you the truth in my eyes they sound like some then you could buy at wallmart witch for car audio lets face it are total waist of money. if it was my money i would buy some then more known to be good like JL memphis maybe even a kicker for an amp (i dont like kicker subs) i would also say ditch the alpine head unit.

now you asked i ansered lets not have an argument over it.

That was more informative.  Just don't understand why someone wants to jump in and criticize something that is not relevant.  No one asked how to install an amp.  But anyways, argument over, truce. 

The brand is pretty good quality stuff.  Far from wal-mart or the flea-market.  It is a small company, and therefore not very popular.  Wanna say they are out of new york or something.  The place I work carried them for a short while.  Nobody sold them, because nobody knew what it was.  They were already discontinued by the time I started working here and I picked up a bunch of their stuff dirt cheap.  We decided to install some of it and turned out to be very pleased.  The subs were very clean and definetely got the job done.  I have the components in both my vehicle's and my lil bro has a set in his ride.  They might not be the best on the market but I threw out my  infinity Kappa Perfect 6.5's to install these and have never looked back if that means anything to you. 

The amps I picked up later on another great deal, and I have been very, very pleased with them.  Over all I would say if you can get a good deal on them, give em a shot.  You will probably thoroughly enjoy them.
