Hey guys any one remember/know the difference between the old rockford amps where it says 800a2 vs 800aII is it just the year? The amps I'm looking at the one with the roman numeral II has dual power and ground blocks so was it a beefeir amp internally? Thx

 

If I remember correct, the second terminals were to connect a cap to. Send Mike Bisson a PM as he was the Rockford rep in those days if IIRC.
