Subwoofers / Speakers

I built my bro a box to house two CDT EF 8" subs. The box is tiny but meets the minimum recommended volume. If the bass is turned up much, whether it be by volume knob, gain, or bass knob, the subs have a high pitched electronic noise. This goes away if one sub is taken out. The only thing I can think of is that the 3" of space between the two magnets is not enough and are causing distortion. Any other possibilities? Oh yea, the subs face away from eachother so the magnets are back to back.

I only have a 4" hole in my door and i need to find a set of mids that will clear. Does anyone know how big the diameter of the magnet+ terminal is? My rainbow mid was exactly 4" and it barely cleared and my AA poly mids didnt clear at all. Heard good things about them and want to give them a try.

I'm looking for a 12" sq sub in the 500-600w range. I haven't been keeping up, but I seem to remember reading that RE products have gone down in quality. I know the IDQ is an all time favorite. Anything else fit the bill?

I have a 98' maxima and want to put the two 10s in a ported box tuned at 28hz. i was thinking this design would be pretty cool and different from a standard square box. this is a top view of the design. thanks to MS Paint

Anyone mess with the CDT mid tweets? Can't remember the model numbers. The concept and size sounds cool, but I'm wondering what the DIY realm thinks of it.

Ok maybe I am making a mistake thinking I'm going to be able to run a good active crossover system on my first system ever. I'll start out with what I do know, if I get a good enough head unit I can run active straight off of it, I don't need anything better than that for now. Also I know that I have room for 6.5" speakers in the doors and 1" tweets in the A pillars. But what is the difference between a 2 way and 3 way speaker? Also I have pretty much no way to go listen to quality speakers unless I want to drive about 3 hours to the only decent car audio store around. So I know you are all going to say that I need to hear them myself to decide but that is just out of the…

I've become interested in getting a pair of these but couldn't find the power handling of these anywhere. Does anyone know what their RMS power is? Thanks

Been doing a bunch of reading and looking for a smaller sub for my car. For the past three years or so, my RLp 15 handled the bass duties, and now I'm itching for a change. It's a great sub, but I want to step down to a 12 or a solid 10. So far I've looked into the Fi Q, Diyma 12, Hertz Hi Energy (I LOVE the Mille, but it's out of my budget, my cousin has a Mille 12...sweet sub), IDQ's, and the Rainbow Profi. So far I'm leaning towards the Hertz. Any other subs you guys have in mind that I can look into? I sort of regret selling my old Brahma 12 MKII. That was a nice sub.

i think i'm stealing andy's idea where he used a sonotube, passive radiator setup. i have a maw12 and a kicker kx400.1, will be using a tube.....now, i need the pr. other then the ones from boston and tc, anyone know where i can get a mach 5 one? lol. actually, looking for a budget one. maybe a mach5 cone/basket?(i know that's not the best way to do this, but it is a budget system in a budget car) thoughts? ideas? links? thanks ahead of time! wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

Set up for so far is Pioneer 9800 headunit, Sundown 100.4 amp, Morel Supremo Tweeter. Looking for a great mid driver now. I have looked at the morel ovations, seas, and the focal. Any suggestions? Budget = around 500 - 600. i just want a great speaker with amazing midrange and a solid midbass.

Well right now I am gonna get either 2 Fi BL or 2 ICONS. They will be wired to 1ohm off my soundstream pca2000d. But in the future i will be getting a zx2500.1. On the kicker site it rates it a 2500 rms at 2 ohms. Are the kicker amps one ohm stable? Cause if i get dual 1's to run off my soundstream amp at 1 ohm then when i upgrade to my kicker amp and not be able to wire them to 2 ohm then i got a problem. I was thinking though if i just got Dual 2's and just ran them off the soundstream amp at 2 ohms for 1500 watts then just be set for when i get the kicker amp. Or can will i be able to wire dual 1's to 2ohms off the kicker?

Hello, I have a friend that just had his sub and amp removed in a unfriendly way from his 2000 Toyota Tundra access cab. He is thinking about putting a new one back in but not visible this time. he was told by a local shop they had a console that could replace his that would have a ten in it. they would of course rape him on the price of that and the install price. I looked around and so far can only find a dual eight under the back seat box. Does anyone have ideas what could work or any other suggestions. He is not proficient with fiberglass or installing. I will do the install but I do not have the time to do a comprehensive install that will take days to do. thanks in…

What are a good 6.5 mid by SEAS and where can i purchase SEA's in general?

so i have my maw 15 in a sealed box 2.7cuft and was wanting to port it this is the largest box i can fit in my reg cab pickup does anyone no what size port to sue thanx in advance

right now i have a jl e6450 amp http://www.carsound.com/articles/publish/article_268.shtml and im getting these type 4 components http://www.alpine-usa.com/US-en/products/p...ng=en&tab=F the amp does 70 watts at 4 ohms and 110 watts at 2 ohms my question is can u wire components to get the 2 ohm load? cause the alpine type r components are 4 ohm and i dont want them getting 70 watts when they can be getting the 110

w/out getting into the high dollar range, are components worth the harder install over co/tri axial speakers? I'm getting my lows (sub) squared away now, I got the Avic D3 head unit, so now it's time for speakers. Currently, I got the stock bose and I'm not sure if I've heard a worse 'premium' set up. I'm going to say I have about $200 to work with for speakers

What is the RMS for these 4inch tweeters. Site says 220 but just making sure if its rms.

ive been wanting the BL for some time now but i think im goin to wait untill springfor a system . but i think i want to throw the alpines in the picture. which set ups will most likely get louder and sound somewhat better with the same power (1.5kw) and which would u choose for a first system?? ive also looked at MAC.com and saw there hellboy and crossover box and the crossover box caught my attention.are these boxes any good?? if so why? thanks

I just wanted to say congrats on building a great driver. If it sounds anywhere as good as it looks(which I know it does) you have a winner. This is hands down one of the best looking/meanest subs I've seen in a while. Its always after I buy a sub something new comes out that I want I'll get one sooner than later....

I just purchased a pair of SEAS tweets and was wondering if I wrapped them with grill cloth over the metal mesh grill if this would affect the sound.

I was looking on your site, I see the mpyre comp set, but the links down. DO you still carry the 6.5 mpyre comp set. ANd if so what do they cost. Thanks, Joe. P

my car has stock 5.25" speakers in the doors and i really wanna KISS on the front stage, with a 2-way. of course i will be deadening and sealing my doors as much as possible, but right now, i dont wanna spend too much on the mids 70 per will probably be the max for me. I have the seas neo metal version sitting here next to me and a set of aa poly mids. the only problem i think will be the fact the stock grill will ONLY fit a 5.25 speaker and i don't want any bad reflections off the inside of the door panel. I wanna HP the mids over ideally around 80hz, but if i must go to 100 i must. For the amps, i will have an Usamps md42 bridged at 180x2 @ 4 ohms so power should…

I'm looking for a 12'' subwoofer to work well in a .7 to 1 cuft enclosure before speaker displacements. Getting about 1000RMS. I listen to a lot of 80% rap and 20% rock and possibly some techno here and there. I was aiming for a Fi Q 12 but i was told that there are subs around that work really well in small sealed enclosures. I want it to be as loud as possible. I also have had a RE SX 12 in a .6 sealed box after displacements. It did really well and sounded clean but it got pretty warm. I'm just exploring my options. Any feedback on woofers is greatly appreciated! Thanks

Ok guys thanks for any help ahead of time. I'm lookin into a 18 BTL but would like your suggestions on speakers.

It's for a friends car stereo, he's got an all eclipse system with an XA-1000 amp (~500w RMS @ 2ohms) that will be powering a MAw15 in a ~3cf box tuned to 33hz. 14.5x2.5" slot port 24" long. Overall box dims will be 29x16x16. Should do quite nicely in his 99 civic coupe I'm kinda sad it's not for me though lol. Pics when we actually start building
