Review DELCO Pontiac Rear Seat Speaker U20 fits 1955

The **Delco 984968 U20** is a meticulously crafted, full-range rear seat speaker designed for classic Pontiac vehicles from the mid-20th century, including the iconic 1955 models. This high-quality audio component embodies the engineering precision and durability that defined Delco s reputation for automotive electronics, making it an ideal choice for enthusiasts seeking authentic sound reproduction in their restored or restored-style vehicles. Engineered with a **19-inch (48 cm) diameter cone**, this speaker delivers a rich, balanced audio experience across the frequency spectrum, from deep, resonant bass to crisp, articulate treble. The **paper cone** is constructed from high-grade, reinforced materials, ensuring long-lasting performance and resistance to distortion, even under demanding listening conditions. Behind the cone lies a **1-inch (2.5 cm) aluminum voice coil**, wound with fine-gauge wire to maximize efficiency and power handling, allowing it to drive both subtle nuances and powerful audio signals with clarity. The speaker s **spider suspension** is designed to provide optimal damping and flexibility, reducing unwanted vibrations and enhancing the overall soundstage. Mounted in a **black, injection-molded plastic frame**, the U20 is built to fit seamlessly into the rear seat compartments of classic Pontiacs, offering a clean, unobtrusive installation that complements the vehicle s vintage aesthetic. Whether used in a custom audio setup or as part of an original-equipment restoration, this speaker ensures that every note, from the smooth hum of a vinyl record to the dynamic peaks of a well-mixed track, is delivered with the warmth and fidelity expected of a Delco original. Perfect for audiophiles and car collectors alike, the **Delco 984968 U20** stands as a testament to timeless craftsmanship, blending historical authenticity with modern audio performance.

### Pros and Cons of buying a Delco 984968 (1955 Pontiac Rear Seat Speaker, U20)

1. **Authentic Fit and Function** This is an original or high-quality reproduction speaker designed specifically for the 1955 Pontiac, ensuring a proper fit in the rear seat speaker location. It will integrate seamlessly with the car s wiring and mounting system without requiring modifications.

2. **Vintage Sound Quality** The U20 series (or similar era) speakers were built to deliver clear, robust audio for their time, often with a fuller bass response compared to modern small speakers. If you re restoring or maintaining the car s original sound, this speaker will provide an authentic listening experience.

3. **Durability** Delco was a reputable brand in the mid-20th century, and this speaker is likely built to last, especially if it s a well-preserved or restored unit. The materials (e.g., paper or early plastic cones, aluminum or steel baskets) were designed for longevity in automotive applications.

4. **Aesthetic Continuity** Using an original or period-correct speaker helps preserve the car s historical accuracy, which is important for enthusiasts who prioritize authenticity in restorations.

5. **Ease of Installation** Since it s designed for the 1955 Pontiac, wiring and mounting should be straightforward, assuming the car s electrical system is compatible. No custom adapters are likely needed for the speaker itself.

6. **Potential for Upgrading** If the speaker is in good condition, you could later upgrade it to a modern high-fidelity unit while keeping the original mounting points intact, making it a flexible choice for future modifications.

7. **Collectible Value** If the speaker is rare or in excellent condition, it may hold value for collectors, though this is less relevant for functional use.

1. **Age and Wear** If the speaker is original to the car, it may show signs of aging, such as cracked cones, weakened voice coils, or degraded wiring. Testing it for functionality (e.g., checking for shorts, resistance, and sound quality) is crucial before purchasing.

2. **Sound Quality Limitations** Compared to modern speakers, this unit will likely have lower efficiency, less bass extension, and poorer high-frequency clarity. It may not meet contemporary audio standards, especially if you re using it in a modern car with amplified systems.

3. **Limited Availability of Parts** Finding replacement parts (e.g., cones, voice coils, or wiring) for a vintage Delco speaker can be difficult. If the speaker fails, sourcing repairs may require specialized suppliers or restoration services.

4. **Compatibility Issues** If the car s audio system has been modified (e.g., with modern amplifiers or digital controls), the original speaker may not integrate well. You might need additional wiring or adapters to ensure proper function.

5. **Potential for Damage** Vintage speakers can be fragile, especially if they ve been stored improperly. Handling them roughly or exposing them to moisture could cause irreversible damage.

6. **Cost vs. Performance** For the price of this speaker, you might be able to purchase a modern aftermarket speaker with superior sound quality and longevity. Unless you re prioritizing authenticity, the trade-off may not be worth it.

7. **Electrical Compatibility** Older speakers often have different impedance ratings (e.g., 4-ohm vs. 2-ohm) compared to modern systems. Mismatches can lead to distorted sound or damage to amplifiers. Testing the speaker s impedance is essential.

8. **Environmental Factors** If the car is exposed to extreme temperatures, humidity, or dust, the speaker may degrade faster than a modern, sealed unit designed for contemporary conditions.

...then a modern replacement may be a more practical choice.

---

- Purchase the Delco 984968 speaker, preferably a restored or tested unit.

- Test it for functionality (check for shorts, proper resistance, and sound output) before installation.

- Pair it with a compatible amplifier and wiring to ensure optimal performance.

- Consider upgrading the car s audio system gradually if you later want better sound quality.

- Opt for a modern aftermarket speaker designed for the 1955 Pontiac s rear seat location (e.g., a high-efficiency 6x9 or 6x10 speaker with a 4-ohm impedance rating).

. Ensure it fits the mounting bracket and wiring harness of the original speaker to avoid modifications.

- Invest in a quality amplifier and wiring to maximize the new speaker s capabilities.

- Research modern alternatives (e.g., brands like Fane, JL Audio, or Rockford Fosgate) that offer speakers with vintage styling but modern performance.

- Consult with a Pontiac restoration specialist or audio expert to weigh the pros and cons based on your specific goals.

Ultimately, the best choice depends on whether you value historical accuracy or contemporary sound quality more. For most enthusiasts today, a balance between the two using a modern speaker with a vintage look may offer the best of both worlds.
