my last mark i took the rear speakers out and put the same pioneer speakers in, but they were 50 rms/ 150 max and were a major improvement.i have a kicker box with dual 12
' in trunk with 1600rms/ 2000 max that pounds the stock interior speakers sound ok but anything is better than a 16 year old paper cone speaker. one person i spoke to said the jbl F3lf 18C807 aa amp was 8 channel 700watt use between 96-98 on premium jbl systems in ford products but couldnt be sure because of overlap in features corresponding to last two letters, aa, ca,fa and ccwhich all look the same and were used in all mark series but couldnt give me any speaker specifics. the rear quarter had a 6x8 and a 3 or 4" round speaker what looked to be mid or sub which i removed and wired the pioneer to the wires from 6 x 8.i think its a 8 channel 8 ohm per output but like i said i couldnt get astraight (or the same answer) anyways. theres one also on ebay that says 700 watt factory mark viii jbl amp i just dont know. the car is still sitting waiting for motor or better deal it will cost 400 to switch my hand controls to something new and tax, tag, title is another 250-300 so ive got to figure that in whatever i do
