H ,ive brout a second hand fusion 10 inch sub,with built in amp .i have already tryed to c if its going to work ,all conectins are fine but no power is running to sub and amp i checked the fusez no problem?do i need a remote to turn the sub and amp on if so wher would get it from,or what might be the problem.thank u four helping me.

need new subs the connection wire to the cone is bad

fusion h/u ca-cd500

try using a ohm meter and if its not making what the factory specs are its most likly it will keep loosing more and more power then stop working which is what ive had happen to me before

has your sub blown, this just happened to me, as soon as i hooked up a differant sub it went back to green the light and worked fine.

open it up if you can and check internal connections to the sub, if all looks good, open up the amp and check the internal fuse. becareful of voltage hazards

you shouldnt have any problems with that amp pushin those speakers it all compatable

No amp is too big, you can turn the gain down. Anyway in my experience people tend to blow up their subs with underpowered stuff anyway (power spikes from clipping). Your amp is rated at 11000watts max and will probably only put out 500 or 600 watts RMS - RMS by the way is the number you should go by. It indicates the usable output w/ out lots of distortion. On the flipside you can power high wattage subs with an underpowered amp and be just fine. However if you wish to extract the most you will need to match amps and subs. A good example of under powered sub applications is in some of my work- I built a wall of nine 12" subs in a bronco, we competed in a 50 watt class and cleaned house taking first in class. Another would be a 150x2 watt amp driving two 15" CV Strokers (1200 watts each). I was going to compete in that class but they made me move up becuase I was an installer at the time. I was upset at first but after my first try I was able to get about 146db and went on to take first anyway. So if the enclosures are built right you can still use that kind of setup. I hope this was helpfull. If you are concerned with exact wattage ratings the manufactures websites should list them. Good luck.

NO it won't be your battery. Sounds more like your deck.

The first thing to try is disconnecting ONE of the two subs. See if you get more bass with a single sub than with both. If you do, re-connect the second subwoofer, but reverse the (+) and (-) wires.
