probably 4 ohms bro. I dont think that sony can handle a 1 ohm load.

depends if the sony is mobile es or not.

If the amp is 2X400 W at 2 ohms, you could wire each of the outputs to its own voice coil. I've never done that, but I've read of others doing it.

^^^^ you could do that, you just have to run both channels off a single input... the little differences in input on L & R can cause some cancellation problems with the sub, and make it sound worse...

best bet would probably be to just bridge it at 4 ohms, just to be on the safe side, till you get your new amp in. sony isnt really that great of quality when it comes to car audio.

I would not recommend running each voice coil off of one side of the amp. Series it to a four ohm load and run it bridged. It will be the same output as 2 ohm stereo or running it to each voice coil but much better. Doubt that amp is one ohm stable.

if they do that then they would be setting the gain with a dmm

Dual Voice Coil Wiring Options | KICKER

That right there is for wiring kicker speakers. I wired mine wrong many of times till I found out this. Its ON there website.

I wired mine parallel/series. My amp didn't take a 1 ohm load very good. I have two L7's 2/4 Impedance.

Was overheating my amp alot. Amyways. Here you go. Try these wiring diagrams.

The only way to find out the ohms of your amp is to either look on the amp and see if it tells you or find the model number of your amp and google the specs.

See if you can find this amp. MTX thunder 6500d. Tell me if you can find what its stable at. I can't find it
