newb, alpine type x 12's

i agree you don't have to have 1000 watts going to those subs...they will do somethingwith less.  the box design has alot to do with things, (ex ; ported, sealed, to small or to large)  the box design will give you the most control over your sound quality as well change the amount of power needed to make the sub perform (less power needed in ported box compared to sealed to get the same output)   the only real prob i see with your stereo design is the price. If your set on running the type x's , then to get the most out of those subs you should run a good amp like the PDX 1000.1.  that setup will get costly if you don't watch yourself. you could get a smaller amp and stil have plenty of boom.  but as haemp stated, there is lots of amps that will produce the power you want.  i personally like the digital design gear ( www.ddaudio.com)  but keep in mind you get what  you pay for as well.  listen to forbidden or haemp. i've been here a while and read alot of there posts and learned alot from what they've wrote

Some subs I can overdrive with 50% more power and they will not fail. By the logic of our new member here, this is not possible as to achieve maximum it is only what the company specs the sub to that is important.

6thaveme, slow down and think before you type. You are coming across as a kid who's voice is starting to crackle from the onset of puberty. If you want to learn, stick around there are people on this site that will provide you the opportunity to do so. The wealth of knowledge here is immense compared to other forums. Part of the reason why, it was already touched on, be an adult. Come back, post again as a adult and see how different the results can be.

I am here to tell you that it CAN be done. One of the VERY FINEST, and I do mean F-I-N-E-S-T sounding stereo systems I have EVER heard in my entire LIFE was a pair of Moondog Audio Horns. Horn loaded front (high-frequency response) and back (labyrinth style for lows), it was one driver per side... ONE FULL-RANGE DRIVER. Powered by a pair of 3 watt (read that again... three watts per channel) Class A TUBE amplifiers (again... T-U-B-E) I had never heard anything sound like it, and still haven't to this day

I am not disbelieving that you heard a great sounding system with only 3 watts going into the speakers.What all you guys are thinking is that i believe that 1000 rms is the nonminal power for two alpine type x speakers.I kno that the enclosure is the main factor for good bass response.I cant stress this enouph to you guys that i am in the industry for spl not sq.I kno nothing about a great sounding system only a chest pounding system that will take your breath away.So when i tell people more watts is the way to go if your goal is more power i mean it.For example my enclosure,kicker l7 in a 4cuft box tuned to 35hz.IM currently giveing it 1200 rms and it does wonders on the term lab meter.Now if i got my box metered with only 600 watts half the power my numbers would go down drastically.Why because the sub wont be moving as much as it was with 1200rms.Im sorry for comeing off as a child who thinks they no everything.When you guys shoot down everything i say i get in a defensive mode and start typing without thinking.I would apreciate if some of you would stop acting like you no everything becuase truth is you dont.Same goes for me i dont no everything.Im here to learn not fight every issue i try and help somebody with.

They wouldent need atleast 1000 rms between the both of them like soundsecurity just said by multiplying power you can gain db.I do spl so for me 1 or 2 db can be the diffrence to win or lose.
