Stereo Information (Wiring, Upgrades, etc...)

[TonyNJ]

Higreat thread, although I can’t find exactly what I’m looking for after searching through many pages.

I have a 2016 ecoboost with the shaker audio system with subwoofer. I have replaced the factory speaker in the sub box with a pioneer TS-A2000LD2 which is an 8” shallow sub with 2 Ohm DVC.

currently, I have wired up exactly as the standard speaker was with a pair of wires to each side of the sub. So each channel is seeing 2 ohms.

My question is and I can’t find the answer, what is the best way to make use of the standard amp? I know I cannot bridge the 2 channels and I’m getting conflicting information on whether I should:
1)run it as I do now using both channels to power a voice coil each

or

2)do I wire the sub in series to show a four ohm load and just use the one channel of the amp? Information of come across suggest the amp is not a true two channel amp and the coils could be fighting each other in the way I’ve got it set up at the moment

Does this help? I have the shaker sub with the original speaker 2ohm dual voice coil. Sounds great wired as per the diagram.
