Features:
The PZ-ZM90.4 4 is a 4 channel amplifier with 720 Watts peak output, 320 Watts RMS power (4 x 80 @ 4 Ohms). You can also bridge the amplifier and get 2 x 260 Watts RMS @ 4 Ohms. Here at PUZU we offer the best value in car audio. We therefore want to make it easy for you to compare our products to any brands on the market. The peak rating can be used to compare with brands who use peak ratings such as Boss and Power Acoustik while the RMS rating can be used to compare with top brands such as Kicker, Rockford, Alpine, etc.
The PZ-ZM90.4 has a conformal coating on its PCB (printed circuit board) in order to protect against moisture, dust, chemicals, and temperature extremes. This coating protects the amplifier from the elements of the ocean. If water gets sprayed on the amplifier you will not have to worry. The exterior screws are made of stainless steel to better withstand the elements. This amplifier is fully marine-rated from start to finish. One of the tricks to determine the real power of a car amplifier is to multiply the fuse rating by 10 to determine the true RMS power. This formula almost always works within 20%. PZ-ZM90.4 features a 2*30 Amp Maxi Fuses. Compare this to other amps on the market with similar fuse ratings and you’ll see that with the PZ-ZM90.4 you are getting your money’s worth and then some.
