    the numbers match up when you calculate it out - so they aren't over rating their amps, which is a sign of a good company for sure.

    I presonally don't believe in the thought of going with a lesser name just because you feel that you will be paying for the name with the name brand stuff. It honnestly doens't make much sense to me. but that's just me, and I've been known to disagree with quite a few people on quite a few things...lol

    Image Dynamic Subs are just rediculous... They are the most amazing subs i have ever heard... I have 2 ten inch IDQ's which were built specifically for sound quality and run with low power requirements... they are perfect for my application... the IDMAX subs are crazy... they have excellent sound quality as well as a very high decibal level... although they do require alot of power, they are amazing subs and you got a great deal

    I thought I had a great deal when I bought a pair for $250 each. even online on elite they sell for more, usually. If that deal was offered me, I'd have to think hard about picking those up on General Principle.

    in case you get tired of sealed and want to play with ported, here it is, straight from the good people who work at ID's mouth into your brain:

    http://forum.elitecaraudio.com/showt...hreadid=118055

    and Rob's car is still the loudest car ive ever sat in under 2000 rms (pair of IDmax in 5.0 ported)

    edit: forgot to give my semi-unsolicited opinion about how they compare with the other subwoofers you mentioned in post #1. the efficiency of the IDMAX alone makes it a TOUGH competitor for ALL those other subwoofers you mentioned. Great, Great subwoofer.

    @Red: I disagree......lol. No, but I don't mind spending money on a better product. I've been learning a lot about car audio, but i'm still a relative noob at it, so it's harder for me to spot a quality product. If the JL is better than the ED, than I'll get the JL, but i'm not sure if it is better. I know that the ED puts out more power, but I also know that it's less efficient....so without listening to either of them....they are pretty much equal in my eyes. The only difference is that JL is double the price....so when I compare them, i compare 2 ED's to one JL.

    @OneFast97Z: Thanks, I heard the same thing about the max's..how they require a lot of power. Hopefully 700 watts per sub will be enough...if not, i can just throw in another ED and send 1000 to each...but i think i'd be pushing my alternator/battery as it is...so i should be ok with just one.

    @WhiteRabbit: Are his subs in a ported box in a 5.0 mustang or are they in a 5.0 cf ported box? Thanks for the link. Somebody on caraudio.com/forum is actually building me a box right now. I told him that I mainly listen to hip hop/r&b/trance and he recommended that I have it tuned to 32-35 hz. Do you think this will be good, or should i ask him to tune the box higher? Also, what would you recommend as a ported box volume? I sent him the idmax specs, but do you think that the subs would sound better in a slightly bigger box?

    5 cubic foot box. 2.5 each. one 12 inch long 4 inch diameter port per subwoofer.

    I think you are at about the perfect tune for music. Any higher, and Id worry about "excessive" peaking, and any lower, and I'd worry about killing my upper bass, and making it impossible to "match" my subwoofer response up to my highs (and still sound good!)

    if you wanna screw around with port tune, I say go for it, its a fun one to play with. However, in this case, I wouldn't mess with box volume too much. 2.5 is a pretty tried and true boxvolume for the maxes, so why mess with a proven number if its been shown to perform DAMN well?

    heres a neat trick you can do if you want to screw around with port tune. go out to Home Depot and buy 4" pipe couplers. The ones at Home Depot are black, but they look like this:

    http://www.radon.biz/ProductImages/f...0-1W-large.jpg

    instead of going with a 12 inch long port, make each about 5 inches long. then slip on that coupler and cinch it on.

    now cut two more pieces of pipe 7 inches long, slip them into the other side of the coupler, and youve got your pair of 12" long ports!

    but now if you want to tune higher, just cut some PVC 4 inches long and insert instead of the 7 inch pieces. or jsut remove the 7 inch pieces! want to try lower tune? insert some 10 inch pieces of pipe in there!

    its a good way to verify whether you can trust the opinions of folks here who say tuning lower is better. Or tuning higher is better. Youll get to see what works best in your car and your ears

    or stick with the ID recommended numbers. you know, whatever

    Thanks WhiteRabbit....lots of good info. If only I would have asked around ahead of time, I could have built the box myself...lol. I'll PM the guy who was building my box to make sure that hes uses 2.5 cu ft. per sub and the recommended porting. I'll post pics of the box and the maxes when i get them installed.

    sounds good. Have you gotten a chance to visit the ID plant yet? they have shows every month. Or used to. Either case, you dont have to go to show off, you can just go and sit in other people's cars.

    or you can have them sit in yours and offer advice/praise.

    or you COULD go to show off

    No, I havn't had the chance. I'll definitely check them out...if they're in SoCal than it would be nice to get some advice....I could use plenty at this point.

    Efficiency is listed at ?? for the efficiency number

    and you'll have your true power

    one question I have about that ED amp....it claims 64% efficiency...yet it's a class D?

    Class D amplifiers are usually > 85% efficient and have a s/n of maybe 70

    that's one hell of a clean, EXTREMELY inefficient amplifier if it's really a class d amp....might want to look into that

    Wow I had to register an account to reply to this bundle of misinformation I have stumbled across. What kind of engineer did you say you are I sure hope its not electrical because you need to go return your diploma and ask for your money back. "14V for current" what is that supposed to mean?.. there is a V after 14 for a reason its volts.... volts is volts a measure of potential. Current is measured in amps.

    The correct calculation to find your power in Watts (equal to the power developed in a circuit by a current of one ampere flowing through a potential difference of one volt) Is Voltage X Current in Amps = WATTS

    This reply is not a flame by anymeans it is mere fact, but like most you will most likely take it as one and right this off as some kind of malicious attack at your level of intellect. But please do some research before you go on some ingnorant bable, people do look these sites up read what is posted and belive it then go tell all their friends what they claim to know. Remember its ok to not know.
