Pyramid CDR-37FD Car CD Player

I bought this unit to use in my golf cart,i needed 80 watts x 2 or close to that,this unit does not have 4 x 40 watts or 160 watts as stated on the box looking at the owners manual it states 7 watts x 2 max output, how does pyramid get away with putting this on the box and on their website as a 4 x 40 watts or 160 watts i dont know but i will never buy from them again, i did hook it up to see if mabe it was an error in the manual but its not, it puts out 7 watts or less x 2 , this unit only has right, left speaker outputs using 1 wire for ground for both speakers and the unit, i bought 2 of theses at a sale and both are the same.
