1 ohm vs 4 ohm which ohm load is best ? Tezla Audio TZ615KD4G2 Subwoofers

Summary

In this informative video, JP the install guy addresses a common question regarding subwoofer wiring for dual voice call systems. He explains the power dynamics between 1-ohm and 4-ohm wiring, emphasizing that lower resistance results in more power but also more heat, potentially reducing efficiency. He suggests high-quality amplifiers for 1-ohm wiring to maintain efficiency. Ultimately, the choice between 1-ohm and 4-ohm depends on the user's preference and system setup, with JP personally leaning towards 1-ohm for maximum power.

Takeaways

• 🎙️ The video discusses the optimal wiring for dual voice coil subwoofers, focusing on the choice between 1-ohm and 4-ohm configurations.
• 🔌 Wiring subwoofers to a lower impedance (1-ohm) allows for more power from the amplifier compared to a higher impedance (4-ohm).
• 💡 The speaker demonstrates this with a 1.5k Series 6 and 1/2 in woofers from Tesla Audio, which are dual 4-ohm and are wired down to a 1-ohm load.
• ⚙️ At 1-ohm, a 1000-watt RMS amplifier may deliver 1000 watts, whereas at 4-ohms, it may only deliver 500 watts.
• 🔥 Lower resistance wiring can lead to more heat generation, potentially affecting efficiency.
• 🛠️ Despite the potential for reduced efficiency at 1-ohm, a high-quality amplifier with good control can still operate efficiently.
• 🏁 The choice between 1-ohm and 4-ohm wiring depends on personal preference and system requirements.
• 👤 The speaker personally prefers 1-ohm wiring for the increased power, but emphasizes the importance of a high-quality, well-tuned amplifier.
• 🔧 A high-quality amplifier is recommended for 1-ohm wiring to ensure optimal performance and efficiency.
• 🙏 The speaker concludes with a personal opinion and a blessing, encouraging viewers to make their own informed decision based on their system's needs.

Q & A

What is the main topic of the video by JP the install guy?

The main topic of the video is about wiring up dual voice call subs and discussing whether a 1-ohm or 4-ohm wiring is better for subwoofers.

What are the Tesla audio 1.5k Series 6 and 1/2 in woofers mentioned in the script?

The Tesla audio 1.5k Series 6 and 1/2 in woofers are dual four-ohm subwoofers that JP has wired down to a 1-ohm load in the video.

Why does JP wire the subs down to a 1-ohm load?

JP wires the subs down to a 1-ohm load because lower resistance allows for more power to be drawn from the amplifier.

How does the power output of an amplifier change with different resistances?

The power output of an amplifier decreases as the resistance increases. For example, a 1000-watt RMS amplifier may output 1000 watts at 1 ohm, 750 watts at 2 ohms, and 500 watts at 4 ohms.

What is the trade-off of wiring subwoofers at a lower resistance?

The trade-off of wiring subwoofers at a lower resistance is that while more power is achieved, it also generates more heat, potentially reducing efficiency compared to a higher resistance wiring like 4 ohms.

Does running subwoofers at 1-ohm always result in inefficiency?

No, running subwoofers at 1-ohm is not necessarily inefficient if paired with a high-quality amplifier that has good control and isn't clipping.

What is JP's personal preference regarding the wiring of subwoofers?

JP personally prefers wiring subwoofers down to 1-ohm to get more power, but emphasizes the importance of using a high-quality amplifier with proper control and tuning.

What factors should be considered when choosing between 1-ohm and 4-ohm wiring for subwoofers?

When choosing between 1-ohm and 4-ohm wiring, consider the power output desired, the quality of the amplifier, and the efficiency of the system.

Why is it important to have a high-quality amplifier when wiring subwoofers at 1-ohm?

A high-quality amplifier is important for 1-ohm wiring to ensure the system runs efficiently without excessive heat generation and to avoid clipping, which can damage the subwoofers.

How does the efficiency of an amplifier affect the choice between 1-ohm and 4-ohm wiring?

An efficient amplifier can handle the lower resistance of 1-ohm wiring without significant heat issues, allowing for more power while maintaining efficiency.
