View Full Version : alpine pdx 5 tuning.

08-02-2009, 11:17 PM
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.

Well see where they respond without distorting..I run most of my stuff on full range or turn on the HP filter at about 50hz, but I also dont beat the snot out of my interior speakers, you can tell when they cant handle it by your ear...

Should I use hp and lp on amp,or the head unit?

Try both. If the head unit's pre-set crossover points don't put you in your sweet spot the amp dials will give you more precise control to help you find it.
