Yes just include what size and where you want us to ship it to

Thanks for the pics guys! Sitting in the Neon was off the chain man....damn that thing is loud

Its definitely a dual 4 ohm sub

7.5 -10 cubes is recommended for a 21......good lord your box is huge

You can take it to a local stereo shop and they should be able to tell you for sure as well......if you dont have any that are close, Im sure a mechanics shop or any electronics repair shop should be able to help you out.

Not sure if you have emailed Nick about this yet, but I would advise you do so if you have not. [email protected] Now, on to the problem......I would love for you to be sure the sub is in fact a D2 instead of a D4 before we have to go through the hassle of sending call tags, building new subs, etc, etc. It would be very easy for someone here to have marked the sticker wrong on the box. If it is wrong, we will fix the problem. Sorry for the trouble, and thanks!

They fit about like an Affliction shirt. I'm wearing a large in the pic and I'm 6'1 and about 195

17 cubes with 240" of port tuned to 32 hz would be killer

We don't list specs on those woofers just because of the custom nature of the build. There are too many coil/suspension variations to give just one general set of specs. A DP will be fine on 4k, but you need to be very careful. Any subwoofer can blow up at that power level.

Glad you figured out the problem

And thats the situation we have

What program are you using to calculate your box tuning? A box tuned to 36 hz shouldn't have any trouble playing songs in the mid 40-hz range. Sounds to me like your box could be tuned more like 28....haha I could be totally wrong, but could you post the internal measurements of the box and your port dimensions?

just for reference, I have 2 15" LI's on a Sundown 1500 (ported) in my car, and my cousin has a pair of the 12's on a Hifonics BX2000d (sealed)

Search for posts by "pawn man". He has a pair of Warden 12's.

wow awesome vid! Thanks for posting!!

Ive talked to Frankie a time or 2 at Finals/SBN, but not sure if he would know me.......seems to be a very talented installer, and overall good guy

Tommy has his own IA line of subs known as the KOB or King of Bass series. He also runs our new 20.1 amps on the subs, and our new 6.4 amps on his mids/highs. He sells those and all of our products in his shop.

Damn Im sexy LOL

Yes, they will be fine

Expensive batteries? Stepdown modules? IDK? lol

Oooh....Nifty Would the .7ohm coils be safe for daily? (series, then parallel the woofers). Depends on what amp you are running, but yes, perfectly safe

Because they are all built on a customer to customer basis, T/S parameters are not available. (i.e. so many different coil/spider combos)

I have 3 4" aeros in my personal car for 2 15" LI's, so Im pretty sure you will be ok for the 12's if you can squeeze 3 in there

If you are running a 3000d I wouldn't recommend building much over 8 cubes per
