  • Question: 30 October 2018
    Car: Peugeot 307 - 2005>

    Would it be possible to wire the door speakers into the amplifier built into the sub?

    in short no it wouldnt, your amplifier wont have the outputs and they are often not full range amplifiers

    Car: BMW 5 Series (E39) - 2004> (E60)

    Is there any additional things I need?

    to install a subwoofer into your vehicle you will need the following accessories, a subwoofer must be connected to the original subwoofers under the seats, or the front speaker lines as they are the only lines that run full range, the rear speakers are on a high pass filter allowing minimal bass through them which means the subwoofer wouldn't work correctly on the rear channels, if you are going to install the SRCA adaptor in the boot you will also require around 5 metres of speaker cable per input.
