When you power up a single subwoofer, you use only 1 channel of the amp right? Or can you use 2? If so, what are the advantages of that? Sorry, i really don't know jack when it comes to car audio.

you can use 2 channels and combine them into one channel. but you can only do that if your amp is bridgeable. (its should say that somewhere, if not, then its probably not). the advantages that you get is more power. usually the amp will send out 50% more power than the use of one channel. but different amps will vary.

 

if your amp allows you can bridge 2 channels (typically take the + from one channel and the - from the other) and combine the 2 and it will give you more power/wattage.. but make sure 1) your amp is capable of that and 2) your sub can handle the increased output (RMS wattage) of the bridged channels...

 

theres also alot of different wiring styles you can do with subs to put more wattage to them, like 2 subs down to 2ohm load etc. etc.

to find more info follow this link...has great pics and everything http://www.jlaudio.com/tutorials/wiring/index.html

click on a sub setup to see the wiring, SVC = single voice coil (your regular sub) DVC = (dual voice coil) a type of sub offering extended wiring options.

Hope this helps
