### **Pros and Cons of the Rockford Fosgate Power 350S (780687302481) 4-Channel Car Audio Amplifier**

#### **Pros**

1. **High Power Output**

The 350W RMS per channel (4-ohm load) delivers strong performance for a 4-channel amp, making it suitable for mid-sized systems with subwoofers, speakers, and possibly a second channel for a second subwoofer or component setup.

2. **Bridgeable Capability**

It can be bridged to 2 channels, providing 700W RMS (2-ohm load), which is useful if you only need a single high-power channel (e.g., for a single subwoofer or a dual-channel setup).

3. **Compact and Lightweight**

The amp is relatively small and easy to install in tight spaces, such as under a seat or in a trunk, without taking up excessive room.

4. **Good Sound Quality**

Rockford Fosgate is known for quality components, and this amp features a Class D design with efficient power delivery, which helps maintain clean sound with minimal distortion.

5. **Remote Turn-On**

It includes a remote turn-on feature, allowing the amp to power up when the car s ignition is on, which is convenient for pre-amplifying sound before starting the engine.

6. **Rear-Output Subwoofer Connection**

The inclusion of a rear-output subwoofer connection (for a second subwoofer) makes it versatile for systems requiring additional bass.

7. **Affordable for the Specs**

Compared to some high-end amplifiers, this amp offers strong performance at a reasonable price, making it a good mid-range option.

#### **Cons**

1. **Limited Channels for Large Systems**

As a 4-channel amp, it may not be sufficient for very large systems with multiple speakers or multiple subwoofers. If you need more channels, you d need to bridge channels or pair it with another amp.

2. **No Built-in DSP or EQ**

Unlike some higher-end amplifiers, this model lacks a digital signal processor (DSP) or advanced EQ controls, which could limit customization for complex audio setups.

3. **No Bluetooth or Aux Input**

It lacks modern connectivity features like Bluetooth or an auxiliary input, meaning you d need a separate receiver or head unit to stream music wirelessly.

4. **No Built-in Protection Features (Beyond Basic)**

While it includes standard protections (like thermal shutdown and short-circuit protection), it may lack advanced features like phase correction or adaptive protection found in more premium amps.

5. **Installation Considerations**

The amp requires a stable power source and proper wiring to avoid voltage drops, especially if it s installed far from the battery. A fuse rating of 100A is recommended, which may require careful planning during installation.

6. **No Head Unit Level Input**

The amp does not have a direct head unit level input, meaning you d need to use a preamp output from your radio, which could introduce signal loss if not properly matched.

---

### **Conclusion**

The **Rockford Fosgate Power 350S** is a solid mid-range amplifier that offers strong power output, versatility, and good sound quality for its price. It s an excellent choice for car audio enthusiasts who want a reliable 4-channel amp with bridging capability, suitable for systems with speakers and subwoofers. However, it may fall short for users who need advanced features like DSP, Bluetooth, or additional channels without bridging.

If you re looking for a straightforward, high-performance amplifier that fits within a moderate budget and doesn t require cutting-edge features, this amp is a great option. For more complex or high-end setups, you might want to consider amplifiers with additional channels, connectivity options, or built-in DSP.

### **Recommendation**

**Buy the Rockford Fosgate Power 350S if:**

- You need a 4-channel amp with bridging capability for a mid-sized car audio system.

- You prioritize power output and sound quality without needing advanced features.

- You re working within a budget and want a reliable, well-built amplifier.

**Consider alternatives if:**

- You need more than 4 channels without bridging.

- You want Bluetooth, auxiliary input, or DSP capabilities.

- You re building a high-end system with multiple subwoofers or complex speaker setups. In that case, look at amplifiers like the **Rockford Fosgate Punch 1200.4 or the Kicker 400-4D**, or higher-end models with built-in DSP.

Details:

I don't repair amps won't even attempt it. I could not find any burn marks. None of the capacitors looked bulged. I tried to power it on made a pop noise.

The only screws missing are the - on left channel. Then some smoke came out of it. I took my time to put it back together so can be shipped. The light never turned on.

I only opened it up so people can decide if is worth repairing.
