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.

2 NTX-6812's. need box and amp.

if your subs are dvc 1000w max and 500rms wiring up to a 1 ohm load you would need a 1000w max 1 ohm stable amp. to put this in a pickup truck, i would not put them in a box, i would get 2 12inch tubes to put them in. cause a wedge truck box would make your system sound like garbage and will be distorted, your sql will be poor, basically you would need the right amount of air space for the subs.

Car subwoofer just past half volume cuts off the amp

Assuming there is no short, or lose ground wire somewhere inside the box, diodes( in the amp) are fine, you might be overheating it by not allowing it to get good ventilation. This can be a big deal on some low end Chinese amps. Or the speakers are blown , or your Resistors (in the amp) are bad, but for arguments sake.
Most people don't use the proper size and or conductivity types of wiring, for pushing high amperage Think about it like this, Watts (power) =.Amps (energy) x Voltage (pressure) Resistance or Ohm's (amount) determines how much Wattage will go in or out, Ohms = Volts x2 / Watts.
What gauge wire are you using on your setup?

Premier sub used to work great ... now nothing

Did you check to make sure that you didn't blow a channel in the amp? Another thing to check would be the connection on the inside of your box, maybe there is just a wire loose.

First you'll need to buy a good quality amp wiring kit. For the torture your battery receives, get a power cap. The higher the farad the better off. And as for sound quality use really good RCA's and speaker wire. Try to keep the amp as close to subs as possible, and speaker wire a the necessary length. Not to long. Be sure to have a good ground.

Sub does not fully work

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.
