ok so i ordered my sub right around valintines day an it took over a month to get here an i finally got time to build a box this week end an hook it up! it never seen power till to day an i thought my amp was fried at first i couldnt get any sound or movement out of it at all.. so i hooked it up to a friends amp an it barely played so we put it back in my car on my amp. when we did that it finally started to play on my amp.. but it barely moves an you cant even here it hardly unless you get close to the sub. i tryed rewiring it a couple different times an it still just doesnt play hardly.. what is wrong with it? i know it aint the amp because i hooked my tens up an they played just fine! so please help me! its a d1 sub wired to 2ohms because my amp does max at 2ohms! all power wire is 0 gauge speaker wire is 10gauge have yellow top and a xs power d2400 in the back have big 3 done up front! i tryed switching my rca cables out an made no difference have good grounds in the back every thing is working fine except for my btl 15! please help me out!!

for starters what kind of model/brand amp do you have? and how do you have it wired from the sub to the amp?

I have a hifonics xxv colossus an from the amp I have the positive from amp to on coil an the negative from the amp to the other coil an the the negative an positive that are left are connected I got the diagram from the12volt.com I wire it to 2ohMs if I confused you sorry!

time to whip out your handy dmm

when you hooked it up to your friends amp did you use your car or his car? and if you can try to hook up a different sub to the amp and see if it works that might help to narrow down the issue. and check the sub with the DMM like stated before, see what the ohm load is on each coil. dont forget to post any results.

Wen I hooked it up on his amp it was threw his car he backed up an we ran wire from his trunk to mine an I then hooked up a pair of tens to my amp an they played just fine! That's why Im askin if it's my new btl sub?

i think i've seen something like this on here before. the VC may be backwards or something. when looking at the terminals i think the + should always be on the left, maybe check that out?

should the - from the amp be on the left, or the - that goes to the + be on the left?

i was talking about the terminals on the sub itself

Sounds kinda like the coils are wired out of phase with each other. Take a small 9v battery and hook it up to each coil. If the sub moves outward, you have the positive on the battery hooked to the positive on the sub. If it sucks in, you have the positive wired to the negative on the sub.

Ok I'll definatly try the battery trick! Do I do that with my wires hooked up? I'm guessing I do but just wana be sure!

here's the video Nick made of how to do the 9 volt trick.

Hope that helped!

What about hooking up just 1 coil?

Do me a favor and throw a metal screw or something steel on the magnet..let me know what it does.

So I'm gunna try all the above after I get out of skool today! What am I looking for when I put a screw on the magnet? Do I have to pull the rubber case of the magnet first?

you will see, nope you do not need to take the rubber boot off

So i tryed the battery an it pops both coils but you can't tell wat way the sub moves.. Can't get the magnet to do anything with a screw i just tested each coil they both read .08 ohms then i put my jumper in to connect the coils like i have been an it read 1.6 ohms.. so i dont know wat to do ive tryed alot of different things and im not getting anywhere!

If a screw won't attach onto the magnet, it was not magnetized.

And do you mean both read 0.8 ohms? They can't each read .08 and then 1.6 together.

If you put it in a regular box with no support that driver will become DESTROYED... if you just opened the box recently reuse it.

yea i still have every thing from when i bought it so it will be the way they shiped it to me! but do i need to get like a RMA# or something like that? i have a paper that says any product sent in without on will be sent back without being looked at all! and also how much is shipping gunna be for this massive beast?

No clue..just fill out the warranty paper that was in with the box with all of your contact information and we'll check it out.

Ok so I've been trying to call warranty hotline all day an haven't gotta answer yet? Is there anybody there or what? Not trying to be rude or anything just wondering

You don't need to call anybody..I told you what to do

Send it in and we'll figure out whats going on.
