### **Cons**
1. **Limited Bluetooth Range**
While the Bluetooth functionality is convenient, the **range is short (typically 30 feet or less)**, which can be frustrating if your phone is far from the amplifier. This is a common limitation in car audio Bluetooth amplifiers.
2. **No Built-in Subwoofer Crossover**
The amplifier does **not include a built-in subwoofer crossover**, meaning you must either:- Use an external crossover (if powering a subwoofer separately).
- Rely on the head unit s crossover settings (which may not be optimal).
This can lead to **muddier bass** if not properly configured.
3. **No Direct Subwoofer Input**
Unlike some amplifiers, the XH901-5 **does not have a dedicated subwoofer input** it only provides a **mono output**. If you want to power a subwoofer from a separate source (e.g., a dedicated sub amp), you ll need to use the **auxiliary input** or another method.
4. **DSP Limitations**
While the DSP is powerful, it **cannot replace a high-end head unit** for advanced features like **multi-room audio, advanced equalization presets, or advanced Bluetooth codecs**. If you rely heavily on DSP features, you may still need a premium head unit.
5. **No RCA Output for Subwoofer**
If you want to **send a subwoofer signal to an external amp**, you ll need to use the **auxiliary output**, which may not be ideal for all setups.
6. **Price Relative to Alternatives**
At around **$300 $400**, the XH901-5 is **mid-range**, but some competitors (like **Pioneer, Focal, or Rockford Fosgate**) offer similar or better features at comparable prices. For example:
- **Pioneer TS-A700DB** (Bluetooth, DSP, slightly higher power).
- **Focal Alpha 500** (better build quality, more refined sound).
- **Rockford Fosgate R1200X5** (higher power, more efficient).
7. **No Built-in Amplifier Protection for Subwoofer**
Some amplifiers include **overload protection for subwoofers**, but the XH901-5 does not explicitly mention this, meaning users must ensure proper wiring and load matching.
8. **Remote Control Battery Dependency**
The remote control relies on **two AAA batteries**, which must be replaced periodically. Some users forget to replace them, leading to inconvenience.
9. **No USB Audio Interface Mode**
While it has a **USB input**, it does not function as a **full-fledged USB audio interface** (like some high-end amps). This means it cannot be used as a standalone DAC for PC audio setups.
10. **Limited Customization for Advanced Users**
The amplifier is **user-friendly**, but **advanced audio enthusiasts** may find its DSP settings **less flexible** compared to standalone processors like **DSP-1000 or XTA-1000**.
