PRODUCT DESCRIPTION

Sundown Audio E-8 V.7 D4 – Big Bass from an 8-Inch Subwoofer

Don't underestimate an 8-inch subwoofer.

The Sundown Audio E-8 V.7 D4 is designed for customers who want real aftermarket bass but don't have room—or simply don't want—to install a large 10", 12", or 15" subwoofer enclosure.

Its compact size makes the E-8 particularly useful in pickup trucks and space-limited custom installations.

A properly designed E-8 system can provide strong low-frequency output while preserving significantly more interior or cargo space than many larger-subwoofer installations.

---

DUAL 4-OHM VOICE COIL – D4

The D4 designation means this version uses a Dual 4-Ohm voice-coil configuration.

That gives installers useful wiring flexibility.

One E-8 V.7 D4

A single Dual 4-Ohm subwoofer can typically be wired to a:

• 2-ohm final load with the coils wired in parallel
• 8-ohm final load with the coils wired in series

Two E-8 V.7 D4 Subwoofers

A pair provides additional wiring configurations, including the ability to create a 1-ohm final load when all four 4-ohm coils are appropriately wired in parallel.

This makes a pair of D4 E-8s a useful match for many 1-ohm-stable monoblock car-audio amplifiers.

Always verify amplifier stability and final impedance before connecting the system.

---

COMPACT 8-INCH DESIGN

One of the biggest advantages of the E-8 is simple: space efficiency.

Not every customer has room for a large subwoofer enclosure.

The E-8 can be an excellent choice for:

• Chevy Silverado
• GMC Sierra
• Ford F-150
• Ram trucks
• Regular Cab trucks
• Extended Cab trucks
• Double Cab trucks
• Crew Cab trucks
• SUVs
• Jeeps
• Cars with limited trunk space
• Custom center consoles
• Under-seat enclosures

Vehicle fitment depends on the enclosure and available mounting space. The E-8 itself is a universal subwoofer, not a vehicle-specific product.

---

PERFECT FOR CUSTOM TRUCK SUBWOOFER BOXES

The Sundown E-8 platform is particularly appealing for pickup-truck audio systems.

An 8-inch woofer allows enclosure designers to build boxes for areas where larger drivers can become difficult to package.

This makes the E-8 V.7 a great candidate for:

Under-Seat Boxes: Maintain passenger space while adding serious bass.

Behind-Seat Boxes: Useful for Regular Cab and other space-restricted trucks.

Center-Console Boxes: Build the woofer into a custom center-console audio system.

Dual 8" Boxes: Two E-8s provide additional cone area while retaining the compact dimensions associated with an 8-inch platform.

---

BUILT FOR PORTED BASS SYSTEMS

The E-8 family has traditionally been well suited to properly engineered ported enclosures; prior E-8 generations were specifically optimized around ported-box performance. For the V.7, the box should be designed using the current V.7 parameters rather than simply copying an older-generation enclosure.

A properly designed ported box can provide:

• Strong output
• Deep low-frequency response
• Greater efficiency around tuning
• Excellent output from a compact woofer
• Powerful bass for everyday listening

The enclosure is one of the most important components in any subwoofer system.

Do not choose enclosure volume or port tuning solely because a box is labeled "8-inch." Match the enclosure to the V.7 specifications and your desired response.

---

WHY AN 8-INCH SUNDOWN?

A common question is:

"Why would I buy an 8-inch sub when I could buy a 10 or 12?"

Because woofer diameter is only one part of subwoofer performance.

The motor, voice coil, suspension, excursion capability, enclosure design, amplifier power, electrical system, and installation all contribute to the final result.

A quality high-excursion 8-inch subwoofer in the correct enclosure can produce surprisingly strong bass.

For truck owners especially, an 8-inch platform can provide an excellent balance between:

Bass + Space + Enclosure Size + Installation Flexibility

---

SINGLE E-8 V.7 VS DUAL E-8 V.7

Single 8" Setup

A single E-8 V.7 is ideal when space conservation is the main priority.

This configuration works especially well for customers who want noticeably stronger bass than factory audio without filling their vehicle with an oversized enclosure.

Dual 8" Setup

Want more output?

Run two E-8 V.7 subwoofers.

A dual-8 configuration doubles the number of drivers and gives the system substantially more total cone area than a single E-8.

Dual E-8 systems are especially popular for custom truck applications because they can provide impressive bass while still fitting into compact enclosures.

PRODUCT SPECIFICATIONS

Important V.7 Specification Note

The E-8 has gone through multiple generations. Older V.5 and V.6 specifications should not automatically be applied to the V.7.

For example, the prior E-8 V.6 was commonly listed as a 300-watt RMS 8-inch woofer, while current marketplace results confirm that E-8 V.7 packages are now being sold.

For that reason, before publishing structured specifications for RMS power, Xmax, mounting depth, cutout diameter, displacement, recommended enclosure volume, or port tuning, enter the exact figures printed for your V.7 inventory rather than copying older-generation numbers.

That keeps your East Car Audio listing accurate for customers, Google Shopping, and AI search engines.
