0 St. Louis, MO. Sep 6, 2011. #13. wiring only one voice coil to a dvc is not bad for the sub, but it does indeed reduce power handling by half. also, the Q will rise, causing a peakier response at resonance. best option at this point is to wire for 4 ohm. VoiceCoils: Dual 4 Ohm and 8 Ohm: Lastly, we'll see a comparison between 2 15-inch subs and a single 18 inch-subwoofer. First of all, the dual 15-inch subwoofer has a wider cone area. This means the 15-inch ones have a higher bass output than an 18-inch sub. So, you should use an 1100 Watt RMS amp for 2 15-inch subwoofers. Greatdeals on Speaker Voice Coils.

It's almost too much for my extended cab Silverado. I love it and will never buy anything other than Scar Audio products. Quality-built, awesome sound, great power handling, and looks as good as it sounds. Asingle 4 ohm woofer on a mono amp gives you a 4 ohm load. Adding a second one in parallel can be calculated by the formula Zt = (Za x Zb)/ (Za + Zb) where Zt is the total impedance, Za is the impedance of woofer A and Zb is the impedance of woofer B. The total impedance in this case is 4 x 4 divided by 4 +4 (or 16 over 8) which is a 2 ohm load. Featuringa 2.5" 4-layer high temperature copper voice coil, the SDR-10 can operate at peak performance for hours on end with the peace of mind knowing that it can handle the brutality. Combine that with the top-tier, high flux ferrite motor of this driver, and it is by no surprise that this subwoofer can reproduce low end bass frequencies with DualVoice Coil (TS-W306DVC only) TS-W306DVC provides two voice coils, each at 4 ohms. This design offers you the flexibility of turning the TS-W306DVC into either a 2-ohm sub (voice coils connected in parallel) or an 8-ohm sub (connected in a series). So you can use a low-impedance amp to produce much bigger, much more powerful bass. boOV34.
