Audiobahn Immortal

XXX re, one has been reviewed by some person and i cant remember who it is but in sealed these babies hit 134.6db look at the possibilities of two in ported. whohooooo 

go to www.reaudio.com . cool ass website. in the contacts they have a phone number, just call and order. if there is a dealer in the area, they'll hook you up through there. can't get them on the internet though, so if you do find one, it's probably defective, don't buy it. only buy from their dealers. they cost about $450, and from what i hear, will kill a JL audio W7 ($999). impresive.

i did a system with 3 10 etrenal subs, and they didn't sound bad. rand about 400 watts each. not real loud, but it did sound ok.

as for power for your subs,  600 watts will be enough to start with, although i would have your local car audio shop build a ported box to put them in.  going this way will be alot easier because you won't have any charging system problems, and the ported box will give you more output for your power. you might as well stick with the subs you have now, because you have them, and once you hear them you might like them alot.  

Kill? As in how? SPL? SQ? Price? Coolness factor? Reputation? Xmax? Materials? Warrenty? Shelf life? Packaging? Bubble wrap?

For those individuals who do not know too much about car audio and come here as a source to learn, it would be wise for others to steer away from making such broad, generalized statements, that, taken at face value, have no basis in fact whatsoever and are highly misleading...Don't be like the marketing department at MTX and not compare things of like properties while saying (with a straight face) "The MTX Sledghammer will KILL a JL Audio W7. Here, look at these facts that we've carefully and meticulously crafted - err, picked to compare the two"...

...and you can get a 13W7 for $550-$650 if you know where to look (I think you were referring to the 13W7, although since you didn't say, I and others have to assume. You also did not supply the size of the XXX you are recommending - 8,10,12,20? eh?). That would also change the model, and hence price, of the ambiguous W7 you are referring to if we were to compare the two subs (W7/XXX) honestly and accurately.
