Easy Walter, $3,000 isn't a bad budget, thats 3 months full time take home salary for some people...
You can get a fine system for that..
On another note $10K in the 70's for car audio systems!!!! WOW, what gear was that? I thought they started going high end mobile audio in the late 80's and 90's I can't even imagine what they had in the 70's....
I cant imagine this guy costing more than 80 bucks...
I had a couple subs back in the day, Orion 2250 amplifier with some 15" JL Audio w1's, long long time ago, mb court components, alpine headunit all in my maxima, lol... came a long way, now I wouldn't dare touch the stereo's in my cars, lol...
