How do you install a subwoofer in a focus wagon?

Answer 1

I have a 2007 Ford Focus 4-door Sedan, and am currently installing my own audio system. I recommend you buy a new Head Unit to start; i recently installed a VR3 VR500CS-BT CD Car Stereo with Bluetooth. You will need a Housing for the subwoofer you decide to purchase; I'm working with a 10" Alpine Type-E subwoofer, a Capacitor because your battery won't likely support even the smallest of Amps while run running the car (Mines a Scorsche 500K 1 Farad), and most importantly, an AMP. Without the Amp, your sub will be a big, expensive, muffled speaker with crappy wiring.. You should buy wiring kits opposed to separate wires as needed, because it's cheaper in the end and likely your car won't need an extra 20' of any cable, because most kits fit in standard installation lengths with a little left over (bout 2' extra). You gotta wire the +12 of your Cap to the + terminal of your battery, and ground the - somewhere in your trunk or nearby. Your wiring kit for the Cap should come with an in-line fuse of around 100A, but you will need to charge the Cap when first hooking it up by placing a 1K resistor between the +12 wire from your batter and the Cap's + terminal until your multimeter reads at least 12V, otherwise your Cap will likely double as a beautiful fireworks display. Then, depending on your Sub woofers chosen, you'll have to connect the amp to it/them, i recommend you go here: to find a suitable wiring guide. You must connect the + terminal of your amp to your Cap's + and ground the Amp's - terminal as well; it can be the same spot used for your Cap, it doesn't really matter. Depending on your head unit, you'll have an array of wiring options. Either a yellow SV/AV looking cable labeled "Subwoofer" or Red and White SV/AV looking cables labeled "RCA out". I recommend you use the RCA out, they are much more clear and powerful. Run the SV/AV looking Audio Cords you get with your wiring kit the same way you would the +12 Gauged wire; under your side sill and into the trunk from under your rear seats, along with a wire (blue should be, but it's just an indicator color and doesnt matter if it's another color) that connects to your head unit's blue "Remote Turn On" wire (This tells the amp when the radio is turned on, and when it should fully go into "Protected Mode", meaning when it should be ready for use with the sub/s. Hook it all together as described (That last set of cables from the Radio Head Unit will go directly to your Amp), ad try it out.. you'll have to adjust the settings of your amp to match your sub's optimum power with your average listening levels tho. (By the way, I'm also using a 300 Watt amp by "Dual".)
