Introducing the NYC Acoustics NSE series of powered, ported subwoofer enclosures. The NSE series is your all-in-one solution to give you huge bumping bass! We combined the amplifier, subwoofer, and enclosure all into one product! This makes installation neater and easier as well. All you need to do is run power, ground and RCA cables and you are done! If your head unit does not have RCA outputs then you can use our speaker level inputs for an easy installation without replacing your head unit.
