[QUOTE="BCotrell, post: 8686191, member: 666314"] Could be a dirty signal causing lack of actual output power (possibly a hu/instal combo). that boss headunit says 80x4 max which is always funny because top of the line headunits put out closer to 50x4 watts max which ends up maybe half of that or lower of clean power delivery. Getting In the 20’s per channel on that hu is probably a stretch So if your instal is correct it could be a small amount of Dirty wattage being delivered causing your resulting sound output. It would only be amplified as you turn up the volume to hear crackling and all that. Relative to instal trouble shootings, You also want to make sure you are getting clean voltage from the battery. Are you tapped into the factory harness correctly? Did you check voltage at speaker inputs behind the deck (where the alpines connect to). Correct install will ensure that the voltage is maximized and transfers into output from the hu internal amp.
