IMO, I still think your current draw requirement is too high. With all the electronics in the car for various systems, I probably wouldn't even want to approach 120A.
I want one class D. No budget. Atleast 1500w rms. Powers a 15" woofer custom enclosure.

dude, i heard sony xplod makes some bombass amps
on a serious note, talking about SPL, I heard one of these the other day: http://www.ground-zero-audio.com/english/05_nw12.htm

now it didnt sound that great, but it wasn't bad for a SPL sub, and boy does that thing move some air.

anyone remember ground zero in the US? well, the mother company in germany is still around and it looks like they are making some really nice subs.

Here is a starting point...



Anyways, read up @ http://www.diymobileaudio.com/ and http://www.caraudio.com/ instead of this forum.
lol i am actually a member on both forums ! thanks for all that copying and pasting i will get my calculator out right now buckaroo

I know its not quite 1500 watts but I'd reccomend a PDX M12 http://www.alpine-usa.com/product/view/pdx-m12/ it uses less than 100 amps of power and mine actually puts out 1345 watts birthsheet. You can find them on ebay with a 1 year warranty for under $500. Personally I am trying to find a way to upgrade my stock alternator or add a second alternator.

I'm just going to answer your question but by no means take it as a recommendation. It seems like you really need to look into this a little more before you dive into this as your knowledge of this platform and basic electronics seems limited and you only act hastily to anyone who tells you anything you don't want to hear.

Lemme teach you guys a thing or two about these particular amplifiers. The sundown seems to be by far the most efficiently rated although I have never owned of those. The us amps which is a great amp btw has three internal fuses 3x40 which makes it actually require 240a fuse ! I have narrowed my amp choice down to these 3 monsters

Let's hope you stick with the boom boom crowd and never attempt to teach math!

Sorry, an internal picture of the amp shows no internal fuses. If you think about it logically, if it really did require a total of 6 40A fuses in parallel, why would they make 3 external and 3 internal. If it actually did have 3 internal, the more logical application would be that the 2 sets of 3 fuses would be connected in series but I can't see why an amp designer would want to do that either.

Since you do not know a thing that your talking about let me clear it up for you since you didnt obviously understand. The Us amps has 3 internal fuses, which makes it 3x40 + 3x40 = 240 retard ! You should give advice if you have no clue what ur referring to ! I dont teach math I just teach smart asses that make weak jokes to stfu

sorry, many users and internal pictures of the amp actually show 3x40 internal fuses. I am not sure why the engineers decided to build the amplifier this way but I have heard it is quite reliable and efficient. Check out this post there are many others that back up what I say...But in all fairness i dont wanna take anyones opinion 100% seriously so I called US amps and the service tech told me the same thing...
