The 6 Best 4 S Max Amps (2023 reviews)

The features department is where boss audio systems 4 s max amp truly manages to shine. The Amp is excellent,get an Amp kit,makes installation go much easier. It is an electrical switch that allows the flow of electrical current. The shield is so weak that even the thin power remote wire causes sound interference. It will power your 300w rms subwoofer. It has lots of power and you can adjust some many things so you can get the right sound for you. The subs can blow the doors off of everything else. They all play together very well and no sacrificing any of the limited space available.

It feels really solid and well made. It is nice to have a wire kit included, just would be better if the wires were of better quality.

You can set exact sound specifications for the bass frequency reproduction

Best runner up: Planet Audio Great Amp

Buy on Amazon

Planet audio great amp is the epitome of what a great amp should be. This Amplifier has 2x 40 amp fuses, 80x12=. It puts out some pretty decent power and it sounds clean. It can be used to power a set of home stereo speakers, but it would require a separate 12volt DC power supply and know how to wire it up. It comes with 1600 high output max power and mosfet power supply, this amplifier is ideal for your entire audio system. It will supply 200 watts per channel, 200 to woofer, 200 to mid-range etc, it does not provide 800 to a single woofer as it is not a bridgeable amp.

The quality of the amp is great. It comes with end caps to hide some of those unsightly wires. It is at least 3 times louder and cleaner than this planet audio.

It runs in 2 or 4ohm configuration and will deliver more power than the standard listing. It's made for the S-Series speakers, so no worries there. As far as install, it's small enough that it's easy to hide.

This amp is part of the S-Series by Alpine and is made/matched for those speakers. If it is used for your front left and right, you shouldn't have any trouble. The best part is, it's still clean at higher volumes.
