Key Considerations Before Investing in a Car Amplifier
Before diving into the world of car amplifiers, it’s essential to understand why you might need one and what to look for. Amplifiers fundamentally solve the problem of insufficient power from your car’s head unit, allowing your speakers to perform at their best, delivering louder, clearer, and more dynamic sound with less distortion. Anyone looking to seriously upgrade their vehicle’s audio, whether for powerful bass, crisp highs, or just overall volume, should consider an amplifier.
The ideal customer for a multi-channel amplifier like the PV3700 is someone who wants to power both their full-range speakers (front and rear) and a dedicated subwoofer from a single, integrated unit. This streamlines wiring and saves space. However, if you’re only looking to power a single subwoofer, a monoblock amplifier might be a more cost-effective and specialized solution. Similarly, if you’re a casual listener perfectly content with your factory system and have no plans to upgrade speakers or add a subwoofer, an amplifier might be an unnecessary expense.
Before making a purchase, consider the following:
* Channels: How many speakers and subwoofers do you need to power? (e.g., 4 channels for speakers + 1 for subwoofer).
* Power Output (RMS vs. Max): Always focus on RMS (Root Mean Square) wattage, which indicates continuous power, rather than peak or max power. Ensure it matches your speakers’ and subwoofer’s RMS ratings.
* Impedance Stability: Check if the amplifier can handle the impedance (ohms) of your speakers and subwoofers (e.g., 2-ohm stable, 4-ohm stable).
* Class (A/B, D, etc.): Class A/B generally offers good sound quality, while Class D is more efficient and compact.
* Features: Look for crossovers (high-pass, low-pass), bass boost, and remote level controls for fine-tuning your sound.
* Size and Mounting: Ensure you have adequate space in your vehicle for the amplifier.
* Budget: Amplifiers vary widely in price, so set a realistic budget.

Diving Deep into Performance and Utility
Having integrated the BOSS AUDIO PV3700 Phantom 3700-Watt Full Range, Class A/B 2-8 Ohm Stable 5 Channel Amplifier into my system, I can confidently speak to its capabilities. This amplifier isn’t just about raw power; it’s about providing a comprehensive, adaptable solution for a genuinely enhanced listening experience in your vehicle.
Impressive Power Output (RMS Ratings)
The headline “3700 W MAX Power” certainly grabs attention, but what truly matters are the RMS figures, which represent the continuous, usable power output. The PV3700 delivers 413 W x 4 RMS @ 2 ohm, 206 W x 4 RMS @ 4 ohm, and can be bridged to 825 W x 2 RMS @ 4 ohm. The 5th channel, dedicated to the subwoofer, provides 1125 W x 1 RMS @ 2 ohm and 563 W x 1 RMS @ 4 ohm. In practice, this means the four main channels pack a serious punch for your door speakers or component sets. They drive mid-range and high-end frequencies with exceptional clarity and volume, easily overwhelming factory speakers and providing ample headroom for aftermarket upgrades. This ample power ensures that even at highway speeds or with windows down, your music remains clear and impactful, significantly solving the problem of weak, distorted audio.
Full Range and Class A/B Design
Being a full-range amplifier means the PV3700 can reproduce the entire spectrum of audible frequencies. This versatility is crucial for a 5-channel setup, allowing it to power both your high-fidelity full-range speakers and the low-frequency demands of a subwoofer. The Class A/B design is a traditional choice for car audio amplifiers, known for its excellent sound quality. Unlike Class D amplifiers, which are often more efficient but can sometimes introduce higher distortion in certain applications, Class A/B circuits prioritize audio fidelity. In my experience, the sound produced by this Boss Audio amplifier is warm, rich, and detailed, with a natural reproduction of instruments and vocals. This matters because it ensures your music sounds as the artist intended, free from harshness or artificial colouring.
MOSFET Power Supply for Stable Performance
The inclusion of a MOSFET (Metal Oxide Semiconductor Field-Effect Transistor) power supply is a significant benefit. MOSFETs are highly efficient and reliable switches that allow the amplifier to rapidly switch between full and non-conduction, delivering consistent and stable power to the output stage. This translates directly into better performance, especially under demanding conditions. When the bass drops heavily or a dynamic passage hits, the MOSFET power supply helps the PV3700 maintain its output without faltering, preventing dips in volume or sound degradation. This stability is key to delivering clean, consistent power and preventing listener fatigue.
High and Low Level Inputs for Broad Compatibility
The amplifier features both high-level (speaker level) and low-level (RCA) inputs. This is a massive advantage for compatibility. If you have an aftermarket head unit with dedicated RCA pre-outs, you’ll use the low-level inputs for the cleanest signal. However, if you’re keeping your factory head unit, which often lacks RCA outputs, the high-level inputs allow you to tap into the existing speaker wires. This flexibility means you can integrate the PV3700 amplifier into virtually any car audio system without needing to replace your head unit, saving money and preserving the original dashboard aesthetics. While high-level inputs can sometimes introduce a slight noise floor if not properly managed, the convenience they offer is undeniable.
Variable Crossovers (High Pass and Low Pass)
One of the most critical features for fine-tuning your sound is the variable high-pass crossover (HPF) and variable low-pass crossover (LPF). The HPF allows you to filter out low frequencies from your full-range speakers, preventing them from trying to reproduce bass that’s better handled by a subwoofer. This protects your speakers from damage and allows them to focus on their intended frequency range, resulting in clearer mid-range and highs. Conversely, the LPF sends only low frequencies to your subwoofer, ensuring it only plays the deep bass notes. These adjustable filters are essential for achieving a balanced sound stage where each speaker and the subwoofer play their part efficiently, avoiding muddy sound and maximizing the effectiveness of each component. This level of control helps you precisely tailor the sound to your vehicle’s acoustics and your personal preferences.
Variable Bass Boost for Tailored Low-End
For those who love to feel the bass, the variable bass boost feature is a welcome addition. This allows you to selectively amplify low frequencies within a specific range, adding more thump and impact to your music. It’s not just a simple “on/off” switch; the “variable” aspect means you can fine-tune the amount of boost. This is particularly beneficial for subwoofers that might need a little extra push or for genres of music that benefit from a heavier bass presence. It provides a quick and easy way to customize the low-end output of the BOSS AUDIO PV3700 without having to adjust other settings on your head unit.
Remote Subwoofer Level Control
The included remote subwoofer level control is a small but incredibly practical feature. It’s a wired knob that typically mounts neatly under your dashboard or in a convenient console location. This allows you to adjust the subwoofer’s output level on the fly, without needing to access the amplifier itself or dig through head unit menus. Driving through different types of music, or even just going from a quiet neighbourhood to a busy highway, often calls for quick bass adjustments. This remote control makes it effortless to dial in the perfect amount of bass for any song or driving condition, enhancing user convenience and overall listening enjoyment.
2-Ohm Stable Design
The fact that the PV3700 amplifier is 2-ohm stable means it can comfortably power speakers or subwoofers with a 2-ohm impedance load. Lower impedance loads allow amplifiers to deliver more power, resulting in greater volume and impact. This stability is crucial when wiring multiple speakers in parallel or using dual voice coil subwoofers, as it expands your speaker configuration options without risking damage to the amplifier. It translates to more power being delivered to your speakers, ensuring they perform at their optimal level and produce the loudest, clearest sound possible.
Bridgeable Channels for Increased Power
The bridgeable feature allows you to combine two channels of the amplifier to provide a dramatic increase in power output for a single speaker. While the PV3700 already has a dedicated subwoofer channel, the ability to bridge the other channels means you could, for instance, bridge two channels to power a very demanding pair of front component speakers, or even another subwoofer if needed, creating a 3-channel (2 bridged for front, 1 for a smaller sub) setup, though it’s primarily designed for its 5-channel use. This flexibility caters to more complex system designs and specific power requirements.
Comprehensive Protection Circuitry
Reliability is paramount for a car amplifier, and the Boss Audio PV3700 includes built-in thermal overload, speaker short, and short protection. These features safeguard the amplifier from potential damage caused by overheating, wiring mistakes, or speaker malfunctions. If the amplifier detects an unsafe condition, it will temporarily shut down to prevent damage, indicated by a protection light. This provides peace of mind, knowing that your investment is protected and your amplifier will last longer, even under challenging conditions.
Frequency Response and Physical Design
The wide frequency response of 9 Hz to 50 kHz ±1 dB indicates that this amplifier can reproduce an incredibly broad range of sounds, from the deepest sub-bass notes to the highest, most delicate treble. This ensures a full and rich audio experience across all music genres. Physically, the amplifier measures 43.2 x 26.2 x 5.8 Centimetres (17” x 10.31” x 2.25”). While this size is fairly standard for a 5-channel amplifier of this power, it’s something to consider for mounting location. It often requires installation in the trunk or under a seat if space allows, ensuring adequate ventilation to prevent thermal issues, despite its robust protection. Its sleek design, part of the Phantom Series, also features multi-LED backlit illumination, adding a visual flair to your car’s interior.
