It is a good idea to run this system if you want to have one speaker for each corner of the vehicle as well as a powerful subwoofer in the back. Another benefit of the best 5 channel car amp setup over a 4-channel is that the subwoofer(s) can get plenty of power without having to bridge the connection.

Best 5 Channel Amp For The Money

1. Rockville dB55 Review – Most Powerful 5 Channel Car Amplifier

Rockville dB55 Car Amplifier

Although a relative newcomer to the car audio market, Rockville has quickly made a name for itself as one of the premier American sound equipment companies.

Rockville’s latest 5-channel car amplifier, the dB55, looks to make its mark by proving it is in keeping with the quality standard set by Alpine, Rockford Fosgate, and the other big-name brands.

Specifications & Features

At a modest price point, the Rockville dB55 is one of the best value 5-channel car amplifiers. A CEA-2006 compliant power source, the dB55 packs up to 4,000W of peak output across five dedicated channels without any hiccups or clipping (assuming it is correctly wired). The dB55 has the following power ratings:

  • 120W x 4 channels at 2-ohm + 500W x 1
  • 80W x 4 channels at 4-ohm + 300W x 1
  • 240W RMS x 4 channels + 1000W x 1
  • 160W RMS x 4 channels + 600W x 1

In our view, the specifications on this amp model far exceed what you would expect based on its unassuming price tag. This is especially true when you consider that the peak output level of this amp can reach as high as 480W at 2 ohms with an additional 2,000W for the subwoofer. At 4 ohms, this amp peaks at an astonishing 320W per channel with 1,200W for the subwoofer.

With a MOSFET power supply, you rest assured knowing that the circuit board is well-designed and will enter protection mode before it short circuits. Since it has an optical coupler, the amp can switch between Class-D and A/B class technology depending on the performance demands.

Bass lovers will rejoice with the dB55 because it comes with a fully adjustable 12dB bass equalizer. With this feature, you can adjust the bass levels to suit your preferences without having to worry about distortion.


If you like your music loud, the Rockville dB55 will make an excellent choice for your car audio system. When we installed it in our vehicle, we found that it provided more than enough power to our rear and front loudspeakers even when we had it far below its maximum output settings.

Although this amp is heavier than most in its class (10.75 pounds), it has excellent performance to back it. If for whatever reason, you are unsatisfied with the output provided by this 5-channel amp, you benefit from peace of mind knowing that it has a 90-day hassle-free return policy.

Setup and Installation

If this is your first time setting up a custom car audio system, you may find that the db55 has a relatively complicated installation process. This is mostly since the Allan key screws provided in the box sometimes do not fit the mounting equipment in some vehicles.

However, a quick trip to your local hardware store can turn a daunting process into a simplistic one provided you pick up the right screws.

  • Superior value for money
  • Plenty of power output for all 5 channels at 2 or 4 ohms
  • Crisp sound quality thanks to built-in equalization technology
  • Mounting screws may not be compatible with every car chassis
  • Heavier than most models and not stackable

2. Alpine PDX-V9 Amplifier

Alpine PDX-V9 Car Amplifier

For decades, the Alpine brand has become synonymous with high-performance vehicle audio. Today, this Japanese consumer electronics company still ranks among the best car audio providers on the market.

However, since the car audio market has become more saturated with competitor brands in recent years, Alpine finds itself having to contend with many rivals.

Luckily, the Alpine PDX-V9 is one of the best 5 channel amp  available today. Below we break down why the PDX-V9 is an excellent choice for audio enthusiasts in need of significant power and personalization.

Specifications & Feature

The Alpine PDX-V9 is a 5-channel digital amplifier that is CEA-2006 compliant and among the most energy efficient models in its price range. The PDX-V9 has the following root mean square (RMS) power outputs:

  • 100W x 4 channels at 4-ohm
  • 100W x 4 channels at 2-ohm
  • 200W x 2 channels bridged
  • 500W x 1 channel at 4-ohm (subwoofer)
  • 500W x 1 channel at 2-ohm (subwoofer)

Built on Class-D technology, the PDX-V9 boasts a total peak power output of 1600W and a total RMS output of 800W at maximum settings. With this model, the maximum output gauge size is 4 AWG and the total harmonic distortion is an impression .01%, which makes for clean, undistorted audio.

If you are a fan of bumping bass, you will be glad to know that there is a bass boost of up to 12 dB available with the PDX-V9. To adjust bass levels, users can use an optional remote bass level control to toggle settings on Channel 5. Further, this model has an impressive high and low-pass crossover frequency range between 30-600 Hz, which allows it to cover a wide variety of sound levels.


When testing the Alpine PDX-V9, we found that its performance was in line with Alpine’s track record of high-quality amplifiers. Not only did this amplifier produce crisp, clean sound through our four 10-inch speakers, but the harmonic distortion was as low as .004%. Consequently, the signal-to-noise ratio was right where you want it to be for a stellar car amplifier.

With this amp, you get the best of both worlds regarding control and power. Not only is every channel capable of fine-tuning and adjustment, but the frequency response can reach as high as 100 kHz and enter sound ranges far beyond what humans can even detect.

Setup and Installation

Unlike most 5-channel amps, the PDX-V9 involves a relatively simple installation process. At less than six pounds, it is light enough to be maneuvered into any car stereo terminal, and its five ports make it easy to snap connectors into. Since it can be stacked vertically, the chassis provides plenty of leeway at the top for another chassis to be installed above it.

  • Sleek, compact build design
  • Comprehensive 1-Year Manufacturer’s Warranty
  • Excellent sound quality and customizable power supply
  • High-performance comes with a relatively high price tag
  • Limited built-in short circuit prevention

Setup and Installation

With plug-and-play functionality, setting up this amplifier is a breeze compared to some of the cheaper models on the market. Although the wiring and hardware are not included in the box, mounting kits are highly affordable and available online, and we recommend using 4-gauge power wires and grounding the power supply.

  • Simple installation process
  • Impressive performance for small size
  • Crisp, undistorted sound even at maximum settings
  • Fully adjustable bass boost
  • 4-gauge wiring and ground leads not included

The PV3700 packs stellar performance despite its lightweight form factor and modest price. During our test run, we found that there was minimal clipping and cut-outs at the maximum output when running it through our 12-inch subwoofer and four Alpine speakers.

Setup and Installation

With the PV3700, setup is relatively straightforward. All of the mounting equipment comes standard in the box, and the user’s manual provides end-to-end instructions for bracketing it to your car chassis and stabilizing it properly.

  1. I bought the boss and installed in a Toyota aristo 1999. Similar to Lexus gs300. replaced stock 10 sub with kicker 10c104 rear 4-inches with kicker 4-inches and front with Alpine 6-inches and a Pioneer xh390bs. Very happy except the lack of easy vertical mounting. Its loud and I discount the power rating as over exaggerated but happy.

    1. Hey Ludwig, thanks for sharing your experience. Sounds like a nice setup, good job! We actually have a double-DIN review article coming out any day now. That Pioneer AVH-X390BS unit is a solid one. Enjoy the tunes, my friend.

  2. Hi. I am looking at buying a system for my daughter’s Jeep Wrangler. However, I have no idea where to begin. I am very skeptical about going to brick and mortar stores because of being a female and not knowing what I am looking for. My budget is about $600-$800. What can you recommend for me? Thanks so much for any advise!!!
