When it comes to looking for speakers, you’ll never be lost for choice, not even in the 4-inch speaker department. Unfortunately, that means that you could be as likely to pick a dud as you would a godlike brand of speaker. That’s why we spent hours compiling a list of the best 4-inch car speakers found on the market and put them on a grueling test that involves a number of our most audiophile staff to see which of them is the one true speaker to rule them all. After hours of non-stop playing and replaying, we decided that the Morel Maximo 4C Coaxial Speakers are the absolute best anyone could find on the market today.

This well-engineered marvel brings out the best of anything we played on it with no hitches whatsoever. And while it wasn’t as loud as our other entries in this list, it was clearly made to make no mistakes and deliver only the best of what is asked of it and if it meant not playing loud enough to make ears bleed, then so be it. But that’s not to say that all the others are junkers that aren’t worthy of attention; we mean the exact opposite. Read on to see why the Morel towers above everyone else and how the others match up against it.

Review Of The Best 4 Inch Car Speakers

Our Pick: Morel Maximo 4C

The main gripe about this speaker is that it’s not as loud as some of the other speakers on this list. However, the Morel was engineered for a quality experience across the board instead of maximizing decibels no matter what. In a side by side test with the other speakers in the list, it constantly provides a beautiful clear and crisp sound at high volumes where the other speakers start to crackle and sound like something akin to a tin can. When it comes to the “flavor” of the speakers, it has some very neat highs and mids with a deep and clear, albeit very subtle, bass. This, all in all, makes for a fairly balanced if not a bit v-shaped sound that is suitable for a wide variety of music. Fair warning: these speakers are a little bit deeper that the average speaker so if you’re not willing to make minor modifications to your vehicle, make sure that it will fit before buying it.

Runner Up: Pioneer – TS-D1002R Speaker with 110 Watts Max. Power 2-Way

If you find our top pick to be too pricey, large, or otherwise unavailable; then our runner up is sure to scratch that audio itch. This Pioneer speaker is a tough match for the Morel, featuring a balanced sound that slightly favors the midrange. The actual speaker cones are a bit smaller than standard 4-inch speakers and use a low power setup. This means that you won’t be able to substantially increase gain without blowing them out.

Cheap Option: BOSS AUDIO BRS40 BRS 4″ 50-watt Full Range Speaker

While the humble BRS40 is absolutely outclassed in terms of performance by the former entries, the Boss Audio BRS40 completely blows them out of the water with how insanely cheap they are. Quality wise, it has a bright analytical sound that emphasizes a decent midrange. On the other hand, the bass is muddy and underpowered and the highs can get tinny at higher volumes. All in all, the BRS40 make for excellent replacement parts, combining a sound range that slightly outperforms most stock speakers with a price that can’t be beat.

Also Great: Polk Audio DB401 Pair Coaxial Speakers

The DB401 was built to rock and roll even in the face of extreme heat or cold, and won’t fade or degrade under direct sunlight. But that’s not all, not only is the DB401 tough, but it’s also loud. The drivers on the DB401 can crank out music at high volumes without much distortion. This does mean that it lacks the finesse and fine-tuning of the other speakers, but they provide a very warm sound perfect for those intense music genres that tend to leave many speakers crying for mercy.

Also Great: JBL GT7-4 2-Way GT7-Series Car Audio Speakers

These JBL speakers are the choice for the bass head. Featuring a generally dark sound, the bass on the GT7-4 is absolutely sublime. A stark contrast to the other speakers in this list, JBL spared no expense to make these bad boys stay on point with its powerful bass that doesn’t distort or clip even at high volumes. Granted, its bass-heavy sound means it’s not very versatile but if you’d rather have the sweet sound of a deep thumping base, then you’d rather go and buy the JBL GT7-4.

Also Great: Rockford Fosgate Punch P142

The Rockford Fosgate Punch P142 are great full range 4″ speakers that are designed to fit a plethora of cars and configurations. Boasting a versatile design that blasts sound that just works right no matter where it’s placed, the P142 is the epitome of installation convenience. Continuing with its jack-of-all-trades theme, the P142 also has an even balanced sound with decent highs, mids, and lows across the board. Though that means it won’t particularly dazzle you like some of the other more “specialized” selections on the list, the Rockford Fosgate P142 4″ speakers will play anything you want as loud and as clear as you want.
