    Aftermarket Subwoofer in 22 M3P

    Got some stuff ordered and trying to finalize a plan for the install. Do you have any diagrams describing your setup? If not any guidance with what I’m thinking so far: Use the constant “12V” power and ground from the OEM subwoofer to power the LC2i Pro. Pinout diagram from a harness. Use the...

    Aftermarket Subwoofer in 22 M3P

    Sounds good thanks. I’ll give it a shot once I get everything ordered and see how it goes. Going to skip the relay/resistor combo at first and see if it’s needed.

    Aftermarket Subwoofer in 22 M3P

    I ended up buying a JD250/1 (JL confirmed it would work <16V) and plan on running it with a 10W1V3-2.

    Aftermarket Subwoofer in 22 M3P

    How long have you had everything installed? I've been reading through threads and some don't seem to have any issues for months (but some have them in days or never get them at all). I'm planning on using this harness to go from the current subwoofer over to the LC2i Pro, then from there to a JL...

    Aftermarket Subwoofer in 22 M3P

    I’ve been looking around for information on and off for about a year now regarding adding an aftermarket subwoofer and amplifier to my car. Anyone have any experience and want to share their setup or issues? For some other info, I have a 2022 Model 3 P with the factory subwoofer in the trunk...
