Let’s review the top 7 amplifiers for MTX terminator subwoofers in detail, including their top features, pros, cons, and what to consider when choosing the best amplifier for car subwoofer.
1. Best Overall- BOSS Audio Systems R1100M
Boss Audio Systems manufactures some of the best amplifiers for car subwoofers. The BOSS Audio Systems R1100M is our best overall pick when it comes to top-quality amps for MTX terminator subs. It delivers up to 825 watts RMS and 1100 watts max power at an impedance of 2 ohms.
Although it’s not the least affordable pick in our review, it’s more affordable than our second pick from Rockford Fosgate. Thus, you’ll get the best value for your money with this amp, considering its premium quality features at a competitive price.
- 2-ohm stable amp- The amplifier is designed as a 2-ohm stable amp. It’s able to feed a MTX terminator with enough power at 2-ohms for louder and more powerful bass. To add to that, it features high level inputs for connecting to speaker levels outputs of a factory or aftermarket radio that lacks RCA. It also features low-level inputs for connecting pre-amp signals from other amps, processors, or receivers via RCA.
- Class A/B amp- Among the features we like most about this amplifier is that it’s a Class A/B amplifier. It features a linear circuit that enhances power output and improves the sound quality. It also allows for reduced distortion while increasing efficiency. It consumes minimal power to output high-quality and powerful sound.
- Variable input control- Another top feature of this amplifier is its variable input control. This control makes it possible to adjust the sound signal coming from the receiver for optimum amplification and the best sound output.
- Subwoofer level control- You can easily control the subwoofer level using the provided wired remote control. You can mount the remote control to the desired location for more convenient usage. By controlling the subwoofer level, you can set it to your preferred level for custom sound output.
- Auto shut-off- It features an automatic shut-off protection mechanism that shuts down the amplifier in case it heats up or when the speakers fail and cause a short circuit. The auto shut-off mechanism keeps the amplifier protected from damage that may result from overheating or short circuit.
- MOSFET power supply technology for enhanced efficiency

What to Consider When Choosing the Best Amp for MTX Terminator Subs
Although we’ve reviewed the best amplifiers you can find today for MTX Terminator subwoofers, they have several differences. So how do you shortlist your choices to find the best one before making a purchase? Here’re the considerations to make to stand better chances of purchasing the right amplifier.
1. Power Rating
The power rating of a car amplifier determines the amount of power it can feed your subwoofer. Essentially, you’ll find amplifiers with two different power ratings including RMS power rating and peak power/maximum power rating. The RMS power rating is more important as it represents the continuous power that the amp sends to a subwoofer. The peak power or maximum power rating is the maximum power peak in short bursts that an amplifier can reach. Ensure the amplifier has an RMS power rating that can feed the subwoofer with enough power.
2. Remote Bass Control
Although a remote bass control feature isn’t a must-have feature, it’s still beneficial in that it assists in controlling the bass output of the amplifier from the dashboard or wherever you choose to mount it. That way, you can control the bass output while driving rather than struggling to reach the amplifier every time you want to adjust the bass output.
3. Protection Mechanism
Car amplifiers work hard to amplifier sound signals and feed a subwoofer with enough power. Thus, they’re prone to overheating. In that case, ensure the amplifier you’re choosing has a thermal protection mechanism to shut it down automatically in case it heats up beyond safe levels. It should turn on once it cools down. Also, it’ll be an added advantage if it has under-voltage and over-voltage protection. Additionally, it should be fused and have an option for grounding.
4. LED Indicators
LED indicators are useful in indicating the current mode of an amplifier. A good amplifier should at least have LED indicators for Power ON and Protection Mode. That way, you’ll be able to tell whether it’s turned on, off, or has gone into protection mode.
5. Frequency Response
Another important factor to consider is the frequency response of the amplifier. Its frequency response range will determine the sound frequencies that it can amplify. In this case, choose the frequency response depending on the kind of bass response you want.
6. Build Quality
It’s also necessary to consider the build quality of the amplifier. It should be made of durable components and a sturdy outer casing for enhanced longevity. That way, you’ll be assured that you’re spending your money on an amplifier that’ll serve you for a long time.
Investing in MTX Terminator subs is one of the best decisions you can make as a car music enthusiast, especially if you love listening to music with intense bass. That’s why you should invest in the best amp for MTX Terminator Subs to get the most out of their bass performance. Hopefully, you’ll find the right amp for your subwoofer from our reviews.
