Need help tuning amp

[jdeaton]

I am installing a pdx-4.100, 6.5 rsd comps (front), and kicker ssmb6 midbass (rear) in my truck on sunday. What should i set the lpf/hpf for the midbass speakers, and what should i set the hpf at for the comps? Also what should the lpf be set at for my sub? (12" tc9... obviously not powered by the pdx)

thanks

Mid-bass and comps are the same? I read you should set LP for subs 10 Hz above lowest frequency of mid-bass (if mid-bass = 70 Hz set sub LP = 80 Hz). And I read that it's good to leave a gap between mid-bass HP and LP sub (ie. sub LP = 80-85 hz, mid-bass HP = 95-100 Hz).

well those are the midbass speakers... any suggestions for the lpf? I really have no idea if it should be like 150hz or 400hz

500hz

500hz

are you sayin that because that says its the maximum frequency response on the website? cause it says the maximum response for the comp vr subwoofers is also 500hz... so idk...

i have no idea about active or passive... i just know its the rsd component system.... its being powered by 2 channels... the kickers are being powered by the other 2 channels. By highs, i assume you mean tweeters?

can you fill me in on this?

thanks

oh also what test tone should i use for setting the gains for the kicker mibass and for the components?

there's many threads on active vs passive. yes, by highs i mean tweeters. but since you're running passive, disregard what i siad. i'm sure you're comps mid can play higher than 500hz. but as far as the midbass, keep it between 60 - 500hz. sub lp 60-80hz. comps hp 100hz. go from there.
