Question about Dual XNBP12D Car Subwoofer

1 Answer

I Have a set of Dual XNBP12D Car Subwoofer and curious about if

When i got them home i realized that they are running on one connection outlet instead of two separate wire hook up's. whats the purpose of that and is it possible to cut into box and connect my own so they run off of 2 channel instead of one?? or is it better to keep it running off one channel together and just bridge my amp to one channel

You need to look at the specifications of the speakers and the specifications of the amp you are hooking them up to. For example: The speakers could be 8ohm drivers wired in parallel which would produce one connection at 4ohms. Most "bridgeable" car amplifiers are very stable at 4ohms. However you must first find out if the amp is "bridgeable" which means it's taking both outputs and adding them together for one monoral output.

Now to the contrary: If both speakers are 4ohms wired parallel, this would produce a 2ohm load and alot of "inexpensive" amps will not work efficiently in a 2ohm load since it creats alot of heat! and will cause an amp to shut down.

Get your manuals out and look at the specifications for impedance.

Lastly, you've got a band-pass box that is specifically designed for a mono load. (one channel) since there is no internal divider between the subs. If you were to run this box in 2 channel or "stereo" the subs would not be moving in unisome and fighting each other for "airspace". Hope this helps

Do you have a fuse on your battery to your amp wire?? If you don't that could easily happen. And make sure you have a big enough ground.

When ever I connect the fuse in the power cable to my car, my car doesn't start. But when I remove the fuse it takes a couple tries then the car starts again. Is the battery my problem?

NO! I hope I am incorrect, but it sounds like a "Dead Short" in your power wire. If you are not fused at the battery and at the amp, you are creating a bomb!. That said, if I'm wrong and you have fuses at the battery and amplifier. God Bless Ya!. What you will need to do is go to any battery house or even Walmart. They can load test the battery and let you know if it has an internal failure causing no cranking amps, yet still reads 12volts on a meter. Second thing to do is check your starter feed from the battery for corrosion, check both sides and make sure contacts are clean and no corrosion has "wicked" up the wire. This can cause your vehicle to eat batteries more than any other issue I have ever encountered. Lastly, never run a car audio system that includes an amp without your vehicle running. That's the number 2 cause of battery failure. Hope this helps. If you need to dig any further, post a comment with all the specifics: Year Make and Model vehicle, then list equipment models. Best of luck

Subs wont light up

i have the same speakers. get a 12volt light tester and make sure that the positive you have going into the light connection on the back has power going to it. not trying to call you out but there are some people out there that just don'y understand this stuff. other than that you can take off the plastic shield and use like a 9volt battery and test each light inside.

Gettin feed baq from the subwofer output when Y splitter is attached to feed RCAs to the amp.

use a "y" adaptor on the amplifier inputs instead of the headunit output. In other words run a single rca line from the headunit to the amplifier but connect to a one female into two male y adaptor before connecting to the amplifier

What would be the ideal amplifier for these subs?

i have the same subs. i am running a total 500/1. i would say not a good idea, just today i was listening to bass mechanic and i could smell the voice coils heating up. so probaly a 300-400 watt amp would be good. just make sure it is a true wattage amplifier. not a cheap amp. pioneer amps that walmart sells are actually good amps.

You have to connect the light to a 12 volt source. DO NOT CONNECT IT TO THE SPEAKER WIRES!!!!! You can use the GROUND and REMOTE terminals on the amp and it will turn on and off with the amp. Also, make sure the little toggle switch next to the light screws is ON.
