How do i get to the voice coil in my 10" xplod? im pretty sure its blown but i wanna take a look.

Connect one voice coil to one channel of the amp. Repeat with the other voice coil. Do not bridge the amp as your only choices would be series which would be an 8 ohm final load and cuts the amp power in half or parallel wiring which results in a 2 ohm load and very few Sony amps currently made can handle being bridged to a 2 ohm load.

No keep on trying end blow everry thing up, Buy some real subs.

• Yea, you blew the voice coil. Pressing on the cone where you are is hitting the spot that is making the coil connect again. Just like a shorted wire. Sometimes you can bend it and get a connection. You are gonna have to replace the sub.

• If you have any comments please feel free to leave them here.
• Hope this helps and thank you for using FixYa.

they best way to do this is with a multi meter on the OHMS setting.... to do this set the multi meter to the least ohms setting, usually it reads 20 or under. Connect the wires to each voice coil (by the speaker wire connections) if the multi meter reads 2 to 4 ohms whichever your speaker is, then the voice coil is not blown, but if it reads 8-10-12-14 or OL which means open loop then the coil in junk.

The polarity of speaker connections verses the connection to the amp should have nothing to do with situation. The sound reiforcement would be weaker in one direction is all.

Make sure the amp was not rated for more power than your speakers. If you overdrove the speakers you may have fried the voice coils.

throw it in the trash

Hello empsglen,

If the sub voice coil is open, you will get exactly no sound. No crackling, nothing.

Use a multimeter to check the sub voice coil. If the meter reads infinity, the coil is open and to the amp, it's as if there's no sub connected, and you will need to replace it.

Hope this helps.

it isnt getting enough power and its tripping the internal switch on the amp and putting it in safe mode. either your wire isnt a high enough gauge. you might need a capacitor or you need bigger wire.

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
