Help 0003 Converting BTA 10100's to Passive

Hello everyone, anyone?

I have a few BTA 10100's that I got off Crutchfield and both stopped working about 3 months after having them installed. One right after the other

From the way they sounded before totally shutting down and from what the installer place said, I'm figuring my issues have to do with the built in Amp's: Both the tubes look virtually new.

Since I have several Amps laying around; is there a simple way to convert my BTA's into Passive Subwoofers?
(I was figuring maybe taking out the Amp unit or snipping some wires?)

Any help is appreciated

If you do decide to bypass the internal amplifiers on the Tubes you need to keep in mind the impedance of each voice coil as well as the power handling limit of the drivers (2 ohm DVC/100 watt power handling limit).

You can simply remove the connection from the internal amplifier to the terminals of the subwoofer, or, remove the internal amplifier completely. However, in going that route you will need to fabricate a back plate for the Tube. Keep all of the polyfill in the Tube.

However, keep in mind that if the Tube's are not a year old they are covered under warranty for repair or replacement if the Tube's are found to be defective. If you still decide to convert the Tube's, just be aware that you do void the warranty.

You can always increase the power handling of the Tube's by replacing the BTA drivers with the passive BT drivers.

Not worried about the Warranty since they're both a few years old (I'm just happy I don't need to throw them away): I'm one of those that doesn't have the time to learn how everyone's return policies work, it just frustrates me to no end...

Since 100 Watt's is pretty useless for a Subwoofer I guess I'd need to look into increasing their power handling limits. About increasing the power handling of the Tube's (by replacing the BTA drivers with the passive BT drivers):

How much are BT Drivers?
Where can I get the Passive BT Drivers?
How difficult is it to replace the BTA Driver with the passive BT Driver?

You can order the replacement drivers through the online store. Either one of these will work if you want to get down to a 2 ohm mono load;

Switching out the subwoofers is quite easy. Remove the fasteners, pull of the grill, remove the woofer and replace.
