Tip & How-To about Car Audio & Video
If you're ever unsure about how you need to wire your subwoofers to get the correct ohm load to your amplifier there are a few resources to help. Usually in the owners manual that comes with your subs and your amp they include a detailed ohm load calculator. First step is to determine what subwoofers you have. Common subs come in a dual 2 ohm or a dual 4 ohm version or a single 2 ohm or a single 4 ohm version. Next determine what ohm load your amplifier is rated at. Mono "subwoofer" amps usually are rated x amount of watts at either a 2 or a 1 ohm load. This means you need to purchase the correct subwoofer combination to match your amp. If youre purchasing 2 dual voice coil 4 ohm subs then to maximize an amp you should buy a mono amp stable at 1 ohm. and Dual 2 ohm subs would need a 2 ohm stable amp wired in series parallel. A great resource for a beginner is to go to www.the12volt.com and on the top of the page find the words "subwoofer wiring diagram" and click on it. This will bring you to a drop down menu where you choose the number of drivers "subs" or "speakers" you have and then you choose the impedence in the next drop down menu. Next you'll be provided with multiple wiring options. Good luck and never think you can't do it yourself. Once you learn it's very easy to retain.
