🔧 How to Choose Based on Your Setup
- Only subwoofer → Go for a mono amp (high power, clean bass).
- 2 speakers or 1 subwoofer → Use a 2-channel amp.
- 4 speakers or 2 speakers + subwoofer → Choose a 4-channel amp.
- Planning future upgrades? → Start with a 4-channel amp for flexibility.
🚗 Real-World Examples (Kenyan Context)
- Matatu with 2 door speakers + 1 subwoofer
→ Use a 4-channel amp, bridge rear channels for sub, front for speakers. - Small car with just 2 speakers
→ A 2-channel amp is enough. - Bass-only setup with big subwoofer
→ Use a mono amp for maximum power.
⚠️ Tips Before Buying
- Match amp power to speaker RMS ratings.
- Check impedance compatibility (ohms).
- Use quality wiring to avoid distortion.
- Consider future upgrades — a 4-channel amp gives more room to grow.
