Question about DHD NTX-6812 Car Subwoofer
About 2 weeks after I bought 2 of these subs I noticed a kind of acidy smell coming from my trunk (I thought it was the box since that was new). Anyways after another week or so I was driving down the road and and lost bass, so of course not being new to sound systems, I checked the fuses on my amp then the fuse leading to the battery, which had blown, no surprise since I am running 2 DHD subs and a 2000 watt legacy amp at 1 ohm. So the problem now is that when I turn the subs on even at a low level it causes my amp to draw insane amounts of amperage, about the same as it would cranked when everything was working. The odd thing is that one sub appears to work fine but the other hardly moves with the same amount of power. If I try to turn the subs past any low level it causes my amp to go into overload protection. Any Ideas would be greatly apprecaited! Also does DHD Power Cruiser have a website?
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.
