Ok guys i posted awhile back about the problem im about to tell you, yet it gets more complex as we try to resolve it.

We had installed a new headunit, spilts, rears and sub + amp into my car. The amp is a 2 channel amp bridged to run my sub only, Both my rears and front speakers are Runing off the headunit. Do Note that i do have LPG on my car. What i explained previously is that i got static all the time and thanks to you guys most of it has gone. I did the grounding, power cable and a noise filter + new alturnator.

Whats happening now is i get static when i accelerate in drive or reverse. Of course it only happens when i put my foot down a bit heavy, it does not happen then the handbrake is applied and rev'd in park or nutural. I love this car, its bloody awesome but i need some opinions on what to do next. My dads starting to think one of the parts in the engine bay is playing up....

Ill list the type of parts im using in my stereo:

ok one the major problems i have encounted after installing professionally is that alot of people run the cables all down the one side of the car which in fact gives you resistance(stactic).
what you have to do is make sure that your power and earth cables are on one side and the rca's and remote wire are run either down the centre or oppisite side to power and earth cable.

id try line filter form jaycar.
or some decent twisted rca's (agin jaycar as them at about $20)
