Subwoofer Wiring?

I am planning to get a mono subwoofer amplifier which i am going to use to play my factory sub in my Terrain.I know that the factory sub has 2 ohms per voice coil, what i am not sure about is how will i wire up the mono subwoofer amp to the speaker. Are the voice coils 2 ohms + 2 ohms = 4 ohms ?. Is it wired in series or in Parallel . Can someone set me straight on this . Thanks.

The stock sub is actually a 2.5 ohms DVC, but they're not wired at the sub in series or parallel. The plug to the stock sub actually has 4 wires and each voice coil is getting its own channel from the stock amp. Not sure how the stock amp is internally wired, but I would think it's still 2 channels for the sub. Just for the **** of it, I removed a stock sub from one of the enclosures I used to modify and sell, to see if anything useful could be done with it. I wired the voice could in series for a 5 ohm load and hooked it up to my Alpine mono amp that's powering my aftermarket 10" sub. I knew the stock sub wasn't going to be able to handle much more power than the stock amp was sending it and I confirmed that VERY quickly. The thing started popping with the bass even turned down drastically!

Don't waste your time trying to power the stock sub with an aftermarket amp. You will most likely blow the **** out if it quickly. The stock sub is mated to the stock amp and that's really all the power it can handle. If you're going through the trouble of adding an aftermarket sub amp, then at the very least, replace the stock 8" sub with one that can handle the power of the aftermarket amp. However, I've stated several times on this forum that IMO, an 8" sub just can't move enough air in an SUV to have any meaningful impact. I would recommend stepping up to a 10" sub, and I'm personally running a pair of 10's these days. One is in my modified stock enclosure, and the 2nd 10" is in a small sealed box that can easily be removed if I need my whole back hatch.

BandDirector you said "The plug to the stock sub actually has 4 wires and each voice coil is getting its own channel from the stock amp". How did you connect them to your amp which is the same amp that i am ordering, did you twist the + together and the - together also and plug them into the amp. Thanks

I figured out which 2 of the wires were positive and which 2 were negative, treated those as 2 channels when I tapped them for the signal for my mono Alpine amp. My 10" sub is a 4 ohm svc sub when I wired it back. My 2nd sub is identical, so they're actually wired in parallel so my amp sees a 2 ohm load.

What about the ANC? If you go with an aftermarket DVC sub how do you wire it to both maintain the ANC and enjoy more power?

V6's, like mine, don't have ANC. I didn't have to worry about it. Only the Pioneer equipped vehicles use the sub for sound, and you have to disable the ANC for that to work...and it's been reported that even then, the sub makes funny low hums & pops periodically. Personally, I'd just tap the back door speakers for my sub signal if I didn't have a Pioneer equipped V6'.

Do you have the Pionner system and are trying to get more power out of the sub? Or do you have the base model and are trying to use the ANC sub for music?

BandDirector ...I have a 2017 Equinox ... not the Pioneer I added a aftermarket amp and sub with audio control processor ... installer tapped into factory amp wires and NOT speaker lead wires ... upon turn on there would be a extremely loud bass/hum for about 5 - 10 seconds ... like LOUD ... what he found after searches . ANC was doing this . if I shut off vehicle with radio ON and start up vehicle I get NO bass/hum . not sure I wanted that he disconnected two wires that control the ANC . I get no bass/hum feedback... but with ANC disconnected I get a CONSTANT noise ( like riding in a shell ) sound ... when I turn off suv after 5 seconds amp powers off and everything is SUPER quiet ... hope im making sense here . what do you think

My only suggestion would be to tap the back door speakers for your signal. Front door speakers are used for phone, etc, back hatch sub is ANC, so the back door speakers are the only speakers left that their sole purpose is music...
