Re: DHD ntx6408 subs
Voice coil has been blown open. Most likely alot of times what I do to test a speaker is connect it to a 9 volt battery. on and off and the speaker should bounce. If not speaker is blown. Plus this way you could save yourself lots of problems. If the speaker was shorted and not blown open. You would now possible have a blown amp and home stereo.

Dhd amplifierDisconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Double check all connections .A thumbs up would be greatly appreciated if this answer is helpful to you. Worth fixing.
this could be your connection to the amp .make sure the positive leads from the sub are on the positive terminals on the amp .first try one sub alone and then connect the other one .with the second one try swaping the terminals but if your using quality products you woudnt have to just connect the leads to the terminals the belong to .positive on positive and negative on negative
have you got the auto ariel lead from the head unit connected to the remote connection on your amp? if not then that is your problem, it turns the power on when you turn on the unit. and turns it off when you switch unit off.
check if you have connected the dvd/rom according to the specifications entered. if no then do it and check again if the player reads the disk. if the problem persists, and i you suspect its the manufacturer's error, then you can get a free replacement according to the warranty details
if your talking box and all, i would say put it in a ported box ( or you can port your own if you know how) other than that make sure they're hooked up at 4 ohms (look up subwoofer wiring diagrams on the internet if you need to be sure) you can mess your sub or amp up going to low on ohms....less ohms = more power.......i hope this is what you were asking....let me know
is the remote lead properly connected to the head unit? if the power led is on then the power cable and earth must be good, check the remote lead 2 your head unit first, if thats all good try looking at the amp to see whether theres a small switch to adjust the output going to the subs, if its very low or right off then nothing will be going through to the subs. if its on high and fine it only realy leaves the neg and pos inputs from the amp 2 the subs.
My guess is that one of your subs has a damaged voice coil, which acts like a short circuit to the speaker outputs. If you put an ohmmeter on the speaker terminals you should measure a resistance of not much less than 2 ohms (assuming you've wired the VC's in parallel). If you measure a significantly lower resistance then you have a damaged subwoofer.
