I couldn't afford the Power 300 to power my two Rockford Pro Series 12's ($380 each in 89'). I went with a Nakamichi PA-400M which was 220 watts x 2 @ 2 ohms. My Rockford subs were DVC 8 ohm. My mids/highs amp was a Punch 150hd with 5-¼" components up front and Rockford 5-¼" coaxials in the rear. My dash had a Sony AM/FM CD player, a half din Sony cassette player (XK-8D), and a half din Rockford pre-amp (PA-1HD). I used a Nakamichi two way electronic crossover (EC-200H). That system cost me $4,500 in 89'. It was in a 89' Ford Probe.
