POWERBASS ASA 600.4X 4-CHANNEL 800W RMS 1600W PEAK ASA-SERIES CAR AUDIO AMPLIFIER - EXECELLANT USED CONDITIONThis is POWER BASS. Bridgeable to Mono and 2 Ohm Stable. Originally bought this for sound competition, but never put the system together. In practically perfect condition and tested. Take advantage of the research Ive done for the best bang-for-buck amplifiers. True High Efficiency Class A/B Design. Dont be mislead by modern digital Class D amps. For the audio enthusiast who is striving for the best analog experience. This is a RARE opportunity to buy an entire family of PowerBass ASA series amps (see my other listings) at a lower price that have nearly the same specifications as the new units. My opinion is these solid aluminum bodies with machined lettering are much more attractive than the new ones. Heavy heatsinks for sustained power output. Buy the complete set of amps I have (separately listed) - They will handle (4) sets of components, (2) subs and (2) mid-bass woofers (at least that was my design). - will consider a package discount. Manual included. Feel free to ask any questions. Be sure to check out my other listings for more professional automotive audio equipment. Guaranteed not DOA. See last picture for other items I have listed. This auction is only for one PowerBass ASA 600.4X 4-channel amplifier.Endorsed by: MERA, CEA, USACi, SEMA and dB Drag!
