How good of quality is a db crossfire 12 inch sub. i think it is a 425 watt.
will post a pic of it in a while

 

another quick question how do you set up an amp to just run one sub do the speaker wires go on the side of the amp that says right or the side that says left

 

your amp should tell you how to run it mono right on the amp or have a switch. it most likely will be + on one and - on the other so you are running both outputs. this will change the ohms by half of what the amp runs in 2ch mode.

 

thanks for the help really helped me out thanks. is it normal for there to be a poping noise when i change the track on the cd player or turn up the volume. it all works and plays fine just when i make a change on the cd player it makes a pop.

 

some radios make noises but i can't tell you if it's normal for yours.

 

it only started doing it after i hooked up my sub and amp. the amp is only running one 12 and isnt hook to any other speakers
