you need an amp and an amp wiring kit
Subwoofers will need to be supplemented with larger auditions to an audio system when they are install in a 1997 Honda Civic. Properly wire the units into the audio system. Be sure to upgrade the ground so the larger additions will not burn anything out. Make sure the subwoofers are also safely mounted to the car.
you just say install sesame
No, you connect the to an amplifier.
i have the same problem did you find out how?
How do I install my output converter to my factory stereo in my car
No
Subwoofers last, for most purposes, the life the car.
yeah, it is a must.
Installing "replacement" subwoofers can be very costly, Factory Cadillac subwoofers are indeed very tricky. You must first purchace the proper sub, then install it as you would any other subwoofer. Your best bet would be to install an aftermarket sub and amp due to the costly BOSE system. If you choose this route you may also need to purchace a RCA adapter, and a factory amplifier bypass harness.
You would need Four DC Audio 7.5k for 15 Digital Designs 9918Z 18 subwoofers.
What I have done before is i attached wires from my door speaker and connected my sub. It sounded pretty good.
Many amps are made for interior speakers instead of subwoofers, so yes.
