Boss - NX3000.4 Onyx 3000 Watt

i bought this amp in December 2021 to power 4 6.5 speakers and a 10" sub. the quality of the sound is impressive for the price and at present i don't have an equalizer, crossover or epicenter and a monoblock amp. in writing this review i purchased those items excluding the equalizer to be place in a 2007 Suzuki Swift. i would recommend this brand to anyone who dont want to use two amps and who needs quality sound at a reasonable price. i am also purchasing the BOSS AR4000D 4000 WATT CLASS D MONOBLOCK CAR AUDIO AMPLIFIER MONO SUBWOOFER AMP to go along with the other amp. its big but heat displacement is excellent and what you need when installing something like this.
