Broke_Audio_Addict Posted October 9, 2016 Report Share Posted October 9, 2016 What type of vehicle? That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

ShadeTreeMechanic Posted October 10, 2016 Report Share Posted October 10, 2016 For the power you are running, grounding to the unibody would be fine. If you get to the point where you have multiple 1/0 runs for positive then you should consider a ground run. I love those cars.

Broke_Audio_Addict Posted October 10, 2016 Report Share Posted October 10, 2016 I always prefer a negative run to the front battery in a unibody vehicle, The path the electricity has to take through the chassis on a unibody vehicle is less than ideal.

ShadeTreeMechanic Posted October 10, 2016 Report Share Posted October 10, 2016 Maybe you could install with unibody ground and get the system up and running. Then add ground run to see if it makes a difference. 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon) Link to comment Share on other sites More sharing options...

Thanks for all your feedback and help.. Link to comment Share on other sites More sharing options...

You can run your ground wires thru a hole in the trunk and connect directly to the frame in the rear. 2009 Pontiac G8 GT 2 Precision Power 12's Power Class 2 Precision Power Phantom P1000.1 Rockford Fosgate Prime 600-4D 4 Lanzar 6.5 components 2 Pyle 8's Audio Control LC2i Stock headunit Link to comment Share on other sites More sharing options...
x infektid x Posted November 6, 2016 Report Share Posted November 6, 2016 that would be correct about the g body being a full frame car.. uni-body cars have the frame built into the body as full frame cars have the body lowered onto the frame. think frame off restoration. you have thee body then you have the frame with the wheels on it. ground the frame , the body then the engine to the body and you should be ok. lots of folks forget to ground the engine . -85 monte carlo ss - if my ears dont buzz. you need more ..
