Brightred6 Posted March 13, 2012 Author Report Share Posted March 13, 2012 (edited) heres the system: -Factory HU -Scoshe Line out convertor with adjustable gains -Autotek 1400.4 Amp -Kicker KS68 Mids and Highs -4ga wire -Ground Isolator Edit: Dont know if this has any effect but the speaker wire from the passenger side is ran with the power wire (is that bad?) either way pretty sure all of the speakers whine, but I will double check that.

andrew018018 Posted March 14, 2012 Report Share Posted March 14, 2012 alternator whine imo is hard to find the exact cause, i usually do the following -ground headunit direct to chassis -ground LOC to where headunit is grounded (if the LOC doesnt have a ground, just twist some wire around the RCAs) -speakerwire wont pick up engine whine, RCAs WILL so keep them away from power wires.. at least 6 inches Quote My System (in VW golf/Rabbit mk2) (1) Hifonics Brutus 2010D @ 1ohm (1) Hifonics Zeus 440 Mids'nhighs (3) JBL W10Gti subs (2) JBL GTO838 (2) JBL GTO936 (1) run of 3/0 Gauge ofc (1) Ac Delco120ah 850cca battery (front) (1) Ac Delco 45ah 330cca battery (rear) (1)Sony Gt630ui hu 34hz tuning Link to comment Share on other sites More sharing options...
