Full audio system fronts, rears and subs

Djvalerio921 · 01-17-2017, 10:39 PM

Ok so I have only the front speakers wired up to the amp as of rn. Waiting on the dual amp kit to come in. I'm not quite sure how to adjust the frequencies on the amp itself. Don't know whether to put it in AP, HP, and LP.

When I adjust my gain sometimes it'll randomly raise and lower by itself, I noticed it does that when I fiddle with the rca cable itself (bought it at oreillys) could it also be a case of shitty rca cables?

Thanks and sorry for so many questions just trying to figure out how to do it myself than take it to a shop and rape me for my money lol

You have shitty RCA cables guaranteed, order some Amazon cheapos or something shielded.

Keep your amplifier on All Pass (AP) and adjust the tuning frequencies in the head unit cross over. Generally keep your crossover at 80hz for speakers. Or 100, if you have nice midrange speakers then 63 will work.
