Replacement birthcertificate for rockford

[moneypit]

Bought a 400-4 rockford yesterday from car toys as a open box. It didnt come with a box or spec sheet. I did a search but just came up with other peoples specs. Can i call rockford fosgate and will they send it to me? Anyone ever done it before? Just curious what the actual specs on it were. If i cant get it, its no biggy. Thanks

They don't have it on file. They write it by hand on it's way out

Just do a clamp on it or take it to a shop who will do it for you.

The birth sheets are most likely done on fixed resistance. A clamp won't give accurate numbers

I thought Rockford used their Power Cube to test amplifiers? It's basically an AudioPrecision that mimics a reactive load.
