  • IDMAX12 D4's?

    I can get two IDMAX D4 12's for $400. Is this a good deal? How do these subs compare with other subs, like the type x's, w7's, re xxx's, brahma's...?

    Hell ya thats a good deal those subs are fantastic. My only word of warning is make sure that you have enough power to run those monsters. I am a big fan of all ID subs. Keep us updated if you get them.

      I will, I'm talking to the seller right now. He says that there is a small dent on the metal cone of one of the subs, but it's purely cosmetic and doesn't affect performance....getting me worried, but it's probably still a good deal.

      What do you think is enough power? I think my amp right now might be able put out 800 watts to each sub.

        the best way to know if ur amp can power those 2 subs is to call ID or email them or post on their forum. I am a total ID fan boy and totally support you buying those subs, they only need about 600 watts apeice to run off. but are you sure you'll be pushing the right amount of ohms for 2 of em? if not check this out too http://www.cardomain.com/shop/wooferwizard.pl

          I just paid for the subs (it was $460 after shipping). The seller said that the dent was purely cosmetic and that they sound perfect...so looks like i got hooked up.


          The way I would wire them would depend on the amp that I'll be getting. I am thinking about upgading to either a Nine.1 or a jl 1000/1. If I go with the Nine.1, I'll be wiring the subs to 1 ohm and that should give them 600 a piece. If I go with the jl, I'll be wiring them to 4 ohm because the jl can only handle 1.5 - 4 ohms.

          Those are the only two amps that I've considered so far. Another option would be to have 2 jl's or 2 Nine.1's...one for each sub. The only problem is that the jl is $600 a piece. The Nine.1 is $350, so it seems like a much better buy. I don't know if a jl is worth the $250 difference. The only reason im considering it is because it would match my jl 300/4.

          Basically, im thinking that i can go with the Nine.1 amp and have 600 watts per sub for now (versus the jl's 500 watts per sub) and later on I can add another and have 900 watts per sub @ 2 ohms a piece.

                I just got the Idmax's last night and I couldn't wait to install them, so I threw them in right away. The magnets on those suckers is huge...i thought my audiobahn magnets were huge, but these things were at least two inches taller....easy. I have them running off my excelon amp which has the following specs:

                KAC-X810D Class D Mono Power Amplifier

                Maximum Output Power: 1600 Watts x 1
                Power Output at 2 Ohms, at 12V (1kHz, 0.5% THD): 600 Watts x 1
                Power Output at 2 Ohms, at 14.4V (1kHz, 0.5% THD): 800 Watts x 1
                Power Output at 4 Ohms, at 12V (20Hz-20kHz, 0.05% THD): 300 Watts x 1
                Power Output at 4 Ohms, at 14.4V (20Hz-20kHz, 0.05% THD): 400 Watts x 1

                I hate it when they give you a maximum output number that can never be reached. I don't know how much power I'm giving the subs, but I wired them down to 1 ohm (even though the amp probably isn't 1 ohm stable) and they sound awesome. I'm guessing that I'm currently giving them around 4 or 500 watts a piece. This is only temporarily until I get the Nine.1.

                  Power (wattage) = Current x Amperage x Efficiency

                  find the fuses on the amplifier, plug that number into the amperage part of the equation.

                  Figure 14v for current as a high, 13 might be more normal (err on the safe more conservative side)

                  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

                    Thanks Red,

                    I never really noticed that about the ed. I'm on the website right now and it says it has a signal to noise ratio of -95dBA and an efficiency of 64%. It has four 30 amp fuses and has a max current draw of 130 amps.

                    The only reason I was considering the ed was because it's so ridiculously cheap compared to the 1000/1 (but then again, what isn't?) I was asking around on caraudio.com/forums and they said that the ed with the idmax's would be a good combo. I found a used one for $250 shipped, so I jumped on it, but do you think I should reconsider?

                    I was also considering the kicker sx 1250.1, the orion 2500d and the orion 1200d. I also saw a viper 1200d refurb for $125 on ikesound, but i wasn't sure if this was a good amp or not. I've heard a lot of good things about the ed, but for $250, do you think there is a better alternative?


                    Some more misc. info:

                    I did the wattage calculation for the ed (im not sure im plugging in the right numbers): power = 14 x 120 (4 30amp fuses) x 0.64 = 1075.2

                    The amp is rated at 1200 watts @ 1ohm (12.5v), but it should put out around 1450 because it's underrated (so i was told).

                      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?
