DESC: Panasonic's amps also come with some great features. A pass-through circuit allows you to easily add another amp; no need to run wires all the way back to the stereo just daisy-chain your system through the CY-PAD1003U. Also, speaker level inputs simplify the job of adding it to a factory sound system. Sound is always a key feature and Panasonic understands that different music styles need different requirements. ThatÂ’s why the CY-PAD1003U features a full set of high and low-pass filters as well as a bass boost so you can get as smooth or as dirty as you want. CEA-2006 compliancy also means that you are getting true power ratings.
