I just had an alpine pdx 5 installed in my 00 blazer, specs are 75x4, and the actual is 110 watts. and the mono channel spec of 300 x 1 has an actual of 422 watts. I have a pair of alpine spr 17s in front, and alpines spr 69c at the rear seat panels. 2 x 12 subs at rear. I would like some advise as to a good crossover setting for both the spr17 s, and the spr69c hp for the front I know need the freq setting, as for the 69c should they be set to, hp or should they be left off for full range. and I need the optimum hz setting. thanks.
