Birth certificate on the 200a4 says May 20, 1999. Which means it was tested then and sold probably 3-5 months after that. Power output on the cert is listed as 352 watts! Not bad. The owners manual says: RMS power at 4 ohms is 25x4. RMS power at 2 ohms is 50x4. RMS power bridged mono at 4 ohms is 100x2.
Please keep in mind that the rated 25x4 watts for this amp is going to be wayyyyyyyyyyy better than the 25x4 power that some of the new decks have. Rockford underrates their amps quite a bit. This amp is going to be alot clearer and louder than any deck could be. Think of the physics involved...the built in amps in CD decks aren't any bigger than your fist, whereas this Rockford amp is massive in comparison. Its going to be plenty enough to compete with a single sub...ever a pair of 10's or 12's. Size is 2.6 x 9.6 x 9.7 inches. The only part that isn't perfect is I don't have the receipt from when it was purchased, so you are going to have a very tough time getting free service work done on it. Its kind of a small risk though...IMO. I've owned a billion different Rockford amps and have never ever had to use the warrenty on one.
Everything is in the box that came with it, the amp has never been hooked up to anything ever. Its just like buying a new one...but without the warrenty. These amps sold for $280 plus tax when they were new, so just a shade under 3 bills. I'll knock off the $80 since there is no warrenty, but I do need $15 extra to cover the shipping, insurance, etc. So $215 and its yours. Just like the other amp: No big deal if you don't want it...just let me know.
