So i want to review another Alpine product that have been out for years. I love the way Alpine Put 4 Chanel into their amps product and i’ve been enjoying fantastic sound.
Having the flexibility that a 4 channel amp gives is great when it comes time to upgrade my system later.
When it comes down to Quality, We don’t need the super – expensive amplifier to enjoy great sound Quality. However, we do need to pick the best that we can get and well-rounded. I’ll tell you might want to know more about the MRV-F300 before BUYING.

ALPINE FIRST MRV- F300 Review – First Impression
Well its good Looking Amp,Very Compact , And well-designed with Dark brushed Metal chassis, well what I could say its feels solid in the hand, but its amazing this amp still relatively lightweight compared to Other classes amps or older amps of the same power rating, that I could say this is innovation.
And from The build quality is great, and I notice there aren’t huge gaps or misaligned parts like on cheaper amps of the same Class D technology. And the fact is compare into past amps with same power rating its weighed 3 times as much as the MRV-F300.
The amp looks great and connectors are high-quality. and you can make a very tight and more reliable connection unlike lesser amps with standard screw terminals. Fit and finish is excellent, with no big gaps or sloppy assembly. The blue light on top glows when it is turned on. My opinion so far? NICE!
Connectors are very high quality and use hex-keyed screws to securely hold wiring connections. Connectors are clearly labeled, and take the guesswork out of bridging the amp if you choose to do so for more power.
The power connectors are circular inside and 8 gauge power wire will fit and is recommended for installation.
I really like what Alpine has done with the protective end caps it comes with – unlike amps in the past, they’re easy to get on and off.
They snap on and off! If you choose to mount it under a seat in your car or truck they’re great for protecting the wiring from shorts if you happen to have tools or coins lying around in your interior like I do at times.
MRV-F300 amplifier design and performance details
Possibility – compact size
The MRV-F300 has glowing light on the top when its powered it indicate its ON. Its Simple But Simple is best as always
There are a multitude of Class D car amps on the market today, and most are pretty compact. The problem is that a well-designed car amp with decent power and GOOD quality sound requires a bigger circuit board and more parts – and that means a bigger size.
Alpine, for several decades, has been several steps ahead of the lesser brands. They use surface-mount component technology (SMT) to reduce the size required in order to make a smaller and better-sounding amplifier. such innovation from Alpine
Measuring only 7 7/8″ W x 6.5″ D x 2 3/16″ H (200 x 165 x 55 mm) it’s Realy Small I can say and can fit in creative places that older amps could never even come close to fitting in, Because of the Size You could even fit one amp under each seat in some cases for a great way to have a multi-amp system that thieves won’t see.
Class D amp technology
Class D amplifiers are one of the most recent developments in the audio world. Unlike conventional Class A/B designs (which most car audio amps still use to this day) that are around 50% efficient, a Class D amplifier uses ultra-fast switching technology to bring efficiency to near 90%!
This means since you are no longer wasting huge amounts of power (which turn into heat, by the way) the amp can be reduced greatly in size and doesn’t need a huge power supply internally.
However, as some people experiencing , that you need to know: Class D amps have higher “noise floors”, another name for the baseline noise or “hiss” level you hear when the gain is turned up.
Also these types of amplifiers need to be well-designed to ensure the technology use doesn’t modify your music signal (distortion) when amplified. To make sure it doesn’t change the result
The end result is the ability to provide up to:
- 50W RMS per channel into a 4 ohm speaker x 4
- 75W RMS per channel into a 2 ohm speaker x 4
- 150 watts RMS x 2 bridged output at 4 ohms (4-ohm stable in bridged mode)
Performance and sound quality
Sound quality is just great as you’d expect from Alpine: music is full and clear, highs are bright and crisp, and bass is solid and easily drives speakers without giving out. It’s an excellent sounding amplifier. The MRV-F300 will lift up all doubts about Class D car amps (after having a few bad experiences) it WILL changed your mind.
If you’re planning to drive subwoofers with moderate power and volume (up to 150W each) you won’t be disappointed. If you need slamming bass, however, I’d suggest the Brother MRV-M500, a mono amp with much more power available in the same size.
The MRV-F300 features full range, low pass, or high pass crossover settings including 50-400Hz adjustable cutoff. A bass EQ (boost) feature is built-in too.
The Most Feature that Everybody want to is Easy and Comfortable to Control right. So MRV-F300 Controls and switches have a good, solid “feel” to them. One thing about Alpine Electronics is their products use good components that don’t feel sloppy when making adjustment, and don’t change due to vibration
This amp is no different.
Note: the bass EQ boost is works only for the 3/4 channel pair when turned on.
One thing you need to know is that because it’s a Class D amp, by nature the noise level can be heard more when the gain is turned up higher. I definitely recommend adjusting the gain to a lower level that will still give adequate volume when the stereo is turned up high.
Additional features and installation
The great news is that it’s still easy to install – just like any other car amp as screw mounting is used to mount on tabs on each end of the amp (one pair of tabs on the control end and one pair on the power & speaker connection side.
It also works with speaker level inputs so it’s great for factory stereos too!
The amp fits great under seats and can still leave room for speaker crossovers! Here’s an example of a custom install using the amp when space is limited.
Actually if needed, because of its light weight, in more difficult installations you could even use industrial strength Velcro or some type of reliable double-sided tape to mount it if necessary. The amp won’t heat up and cause the adhesive to lose strength.
You’ll get the following inside the box:
- 5″ Speaker-level input harness
- 2 Snap on terminal covers
- Four 3/4″ Self-tapping hex-head screws
- Owner’s manual (English/ French/ Spanish)
- Alpine Verification Certificate
…so you’ll need to remember to pick up whatever else you need before you start your installation, along with an amp wiring kit. I recommend picking up a good quality but great-priced 8 gauge wire kit like I found at Amazon.
For your convenience I’m including the specifications directly from the owner’s manual as well as details I’ve found myself.
