HDS2.2 Series Car Speakers Subwoofer: Come in a 6.5", 8", 10", 12", 15" Sizes so listening truly becomes an experience! Add bass to your daily driver with the affordable Heavy Duty Street Series car audio subwoofer. The oversized 100 oz magnet handles 600 watts of RMS power from your amplifier with dual rather than single subwoofer voice coils. This is a subwoofer for car audio enthusiasts at all levels can appreciate. Beat the Heat: Heat kills coils! Like any speaker subwoofer voice coils collect heat, especially at higher power levels. The vented electroplated back platelets heat escape smoothly with less turbulence in the coil gap. Designed to withstand temperatures over 350 degrees (F), the high-quality copper coil wire guarantees reliable long-term performance. Dual Voice Coil: The HDS2.2 series comes with 2.5” diameter, four-layer subwoofer speaker voice coils withstand high temperatures by incorporating high-quality wire and high-temperature adhesives. Having two coils allows for series or parallel wiring. With either 2 or 4 ohm impedance options, you can make your subwoofer car subs happy by wiring for the correct RMS power from your amp. Built for Bass: With 100 oz of the magnet, this is not a small subwoofer for car motor! A cast aluminum frame supports a three piece suspension and non-pressed fiber reinforced cone for maximum efficiency and lower tuning in a ported enclosure. The conical back plate allows for longer voice coil travel while the wide, tall surround allows for a long, controlled excursion.
