Best Monoblock Amp

monoblock amplifierBuying an amplifier for your car audio system can be a daunting task especially if you’re new to the industry and have no experience in this field.

So, if you’re a newbie, the first thing to do is to read our unrivaled car amplifier buying guide in which we explained in details all the relevant specifications and guidelines of how to choose the best amplifier for your vehicle.

Car amplifiers are definitely part of the picture if you want your music to be loud. Also, because subwoofers require significantly more power than an aftermarket or factory-installed receiver can provide, a separate amp is a necessity.

External car amplifiers are categorized by the number of channels. In other terms, the number of speakers they can power simultaneously. There are multi-channel and mono channel amps. For the purpose of this article, we’ll be reviewing a few of the best monoblock amps on the market.

Unlike multi-channel amplifiers that can power an entire audio system, monoblock amps are designed primarily for subwoofers. Many mono-channel car amps use class D circuitry, which makes them energy and heat efficient. Class D amplifiers tend to distort at high frequencies, but this is not usually an issue when they are used to power subwoofers.

So what are the best monoblock amps out there. Read on to find out.

5 Best Monoblock Amplifiers Reviews

1. Rockford Fosgate R750-1D Review

Rockford Fosgate R750-1D ReviewRockford Fosgate offers a wide range of various car amplifiers. Their amps come in three categories labeled “Prime”, “Punch” and “Power”.

Rockford Fosgate car amplifiers seem to hit the sweet spot for a lot of guys, probably because they are in more of a low-mid price range. RF amps are no joke and are highly recommended to those looking for great quality equipment at an affordable price.

The R750-1D is one of the best mono channel amplifiers that Rockford Fosgate has to offer. This class D amplifier has plenty of power to offer despite its relatively small size.
