I've got an old Blade amp. I've never heard tell of this line of stuff...It's a G series G1254 500 Watts 4 channel. It says its got crossover parametric bass boost on it. What is that? Just the bass boost switch? Is this a good amp or just another line of junk? I know its 10-15 years old.
I've also got a 750 watts Ultimate amp. I guess these are made by audiovox now...? This amp is also 10-15 years old and still runs strong. I just want to know if they're worth anything and how good they were back in the day. Thanks!
