You should definately bridge them. Firstly, lay the 2 speakers face down next to each other. Note the connections +- +-. The first + will go to the amplifier. The next terminal(-) will be connected to the next speaker(+). Take the last(-) and connect to amplifier. Please note that your amplifier has a bridge section which is normally the first + and the last- on the two channels. Connect your woofers on the bridge.

its behind the magnet but you cant replace just the voice coil you need a whole new speaker

do you have a power on signal wire hooked up?

What kind of subs are you running? Meaning what brand, what are the ohm, spl and wattage? I'll look up your amp while you get that info to me. Looking forward to helping you:) Thanks!

go to the sony website or any dealer website and look at the model number of your sub, punch that in and get the measurement.. mostly gonna be inches.. but then go to google and convert it to mm

A faulty voice coil may be to blame on one of the subs...when it heats up it starts to act up leading to a undesired preformance.
