well, i got my system finished and working. it always worked great... but now there are issues. when the engine is running, there is intereference from the ignition, and it plays through the damn subs. volume, and sub level have no bearing on the sound, it's always there. i'm thinking that one of two things has happened. #1. either my ground was never great in the first place... and it's juss now showing. or #2... it's fine, but loose @ the amp. what do ya'll think?the amp is under my trunk floor... so i haven't had a chance to check it yet. any input will most likely be helpful. thanks guys

 

find a different ground spot, and make sure your rca cables are not crossing the power wire

 

damn. whats funny is they do cross the power cable. i know it for a fact

 

try checkin your rcas from the back of the radio as well. one of my rcas came off for my subs and for the longest time i couldnt figure out what it was until i pulled out the deck and saw a rca was unplugged.

ps. check your grounds, the rcas running over the power wire may also be a factor but it is not always true. my boy has got his rcas ran over with power wire and he gets no noise. i had mine ran the same way and no problems. u also might have bad rcas

 

it's a cheapo wiring kit... when i change subs, i'm changing the wires anyway. rcas may have crapped out

 

i dont think you should worry about the rcas crossing with the power wires. i run them along the same side. i have no whine what-so-ever. check your rcas. then redo your ground.

 

it all depends on the brand of rca's.. the cheap ones hes using might not be shielded, in that case it will pick up interference from the power wire.. just upgrade the RCA's with something better (fosgate, stinger)..

 

^yep thats true, didnt think of that
