Skar Audio 6.5 Subwoofer Lineup: Which Model Fits Your Setup?

Best for: Custom single-sub builds needing 1-ohm wiring

The Skar Audio EVL-65 D2 6.5″ 400 is an individual raw component driver designed for custom enclosure projects. Built with a dual 2-ohm voice coil configuration, this model gives car audio builders the flexibility to wire the coils in parallel to present a 1-ohm final load to a monoblock amplifier, or in series for a 4-ohm load. The driver is engineered around a hefty 39-ounce motor structure and features an advanced air flow cooling system to dissipate heat during intense listening sessions. Its competition-grade pressed paper cone is mated to a high-roll foam surround, allowing for deep excursion and responsive low-end frequency delivery.

This standalone skar audio EVL-65 D2 suits the hobbyist or installer who wants to craft a tailored fiberglass pod, underseat enclosure, or center console baffle. With a conservative power rating of 200 watts RMS and 400 watts peak, it pairs effortlessly with small-footprint class-D amplifiers. The driver features an aluminum enclosure listing specification, a resonant frequency (Fs) of 61 Hz, and an operational frequency range of 50 to 250 Hz with an 83.1 dB sensitivity rating. It gives way to pre-loaded models for buyers who prefer to skip woodwork and wiring calculations entirely.

Best for: Trucks and compact cars needing drop-in bass

The Skar Audio EVL-1X65D4-V-LP 6.5″ 400 Watt provides an all-in-one bass solution that eliminates the time, measuring, and cutting required for custom fabrication. This skar audio 6.5 loaded enclosure houses a single EVL-65 D4 subwoofer inside a low-profile slot-ported box constructed from 5/8-inch high-strength fiberboard MDF. To streamline installation, Skar Audio pre-wires the dual 4-ohm driver internally in parallel, presenting a ready-to-connect 2-ohm final impedance at the exterior spring terminals.

With an enclosure total depth of just 5.25 inches, this system is specifically engineered for tight truck cabs, compact trunk corners, or storage cubbies where depth is strictly constrained. The slot port is tuned specifically to 56 Hz to optimize air movement and maximize output from the single 200-watt RMS driver. A heavy-duty metal mesh grille is pre-installed to protect the cone from cargo, luggage, and shifting equipment, while premium black carpeting gives it a clean aesthetic. This unit gives way to multi-subwoofer bundles when total cabin volume demands greater cone area and higher power handling.

The Skar Audio dual-driver package contains two matching EVL-65 D2 subwoofers in a single bundle. Each woofer features a dual 2-ohm voice coil, giving fabricators a wide range of wiring possibilities when designing a dual-driver enclosure. When wiring two dual-2-ohm subwoofers together, you can run all voice coils in series-parallel for a final 2-ohm load, or run every coil in parallel for an ultra-low 0.5-ohm impedance load on specialized competition amplifiers.

This skar audio 6.5 pair delivers a combined power handling of 400 watts RMS and 800 watts peak, doubling the total cone area and air displacement compared to a single driver. Each unit features a 2-inch pure copper voice coil and a substantial 39-ounce single-slug ferrite motor to control cone excursion during sustained bass notes. This bundle is best suited for seasoned audio enthusiasts who want to build a custom dual-ported enclosure for a truck or hatchback. It gives way to the dual-4-ohm package if your specific amplifier requires a standard 1-ohm mono load.

Best for: Dual-subwoofer systems paired with 1-ohm amplifiers

The (2) Skar Audio EVL-65 D4 6.5″ bundle provides two dual-4-ohm subwoofers engineered to solve a common impedance matching challenge in multi-driver setups. Wiring two dual-4-ohm woofers in parallel results in an exact 1-ohm final load at the amplifier terminals. Because the vast majority of modern class-D monoblock car amplifiers generate their maximum rated wattage output at a 1-ohm load, this specific bundle allows installers to extract optimal power without pushing equipment into unstable impedance territory.

Each driver in this skar audio EVL-65 D4 bundle handles 200 watts RMS and 400 watts peak, combining for 400 watts RMS across the pair. Both subwoofers feature 2-inch pure copper voice coils, 39-ounce single-slug ferrite motors, and heavy-duty suspension designed to withstand intense low-frequency reproduction. This package suits custom-box builders who prioritize clean electrical efficiency and widespread monoblock compatibility. When compared to the pre-loaded box, this dual set yields significantly more output but requires dedicated enclosure construction.
