Sub wiring

Bought a cheap sub for our Mav (which was supposed to have the upgraded stereo with extra speakers and sub but dealer messed up the 22-23 transition).

I have it all wired up and working but the high-gain inputs (tapped front speaker wires) is supposed to trigger it turning on, but it never turns off when the stereo turns off.

I have a dashcam wired to back window, I could splice that wire for the blue wire "input signal" for the sub. But would I connect to the positive or negative of the dashcam?...

Yes forgive my cheap engineering- I used the existing bracket behind the back seat with the cheap ($150) sub. Sounds pretty good but I don't want the battery dead from the sub always staying on....

I've always had problems with auto on/off on subs not working properly.  I always just leave my subs on, but that's indoors where they are plugged in, so no big deal.

My guess would be connect it to the positive of the dash cam, but not entirely sure.  Either might work, as the sub is probably just looking for a change/spike in the current to trigger the switch.

If it were me, I'd wire in an in-line on/off switch that I control myself...though that might be kind of annoying in your DD, might forget sometimes, etc.

TL;DR, I'm not of much help.  Try it, see what happens. :huh: :lol:

LOL I'm very much of the same mindset- wife may or may not like manual on/off switch, she drives Mav to work most days. (I drive when we're together, or if it's definitely going to rain she or I will take minivan (instead of me driving Miata).

Tried the negative and positive wires from the dashcam power cord- sub still stayed on.

The instructions for the "auto power on" button were counter-intuitive. I had to turn it off. Works perfectly now.
And yes, I've been messing with it this entire time since original post....

So, the sub is a great addition and well worth the headache of install!

When you push the button to turn the truck off the sub immediately cuts out even though the radio/Pandora keep going for a couple minutes or until the door is opened (whichever is first). The stock stereo isn't terrible but I've always loved bass and it's quite full with the addition.

Not enough to rattle the neighborhood, even at max bass knob.
