You can use one channel for a dual woofer setup.
No
Subwoofers last, for most purposes, the life the car.
you need an amp and an amp wiring kit
yeah, it is a must.
You would need Four DC Audio 7.5k for 15 Digital Designs 9918Z 18 subwoofers.
First you will absolutely need an amp to power any subwoofers. Nowadays subwoofers come along with amp..& normally one 1200watt subwoofer decrease your car battery lifetime to 2-4 month
There are two types of subwoofers. 1. Active subwoofers 2. Passive subwoofers An active subwoofer will have a built-in amplifier. A passive subwoofer doesn't have a built-in amplifier which will require the use of an amplifier, the use of a power source.
No thanks...I got a nice 4000 watt system.
no, a factory CD player can be used in a vehicle that has subwoofers attached. as long as the factory CD player in the vehicle has treble, bass, and subwoofer controls on it, it will be fine. if not, an aftermarket CD player will be the solution. with subwoofers, you need to control the amount of power that are ran through them. the amplifier is a control, but if not set correctly on the CD player, you could blow your subwoofers.
To power your speakers, and to ensure that your amp has enough power to power your subwoofers, you would need at least an amp of 750 watts true power.
no, i really dont think there is a real need to do that anyway.
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.
