RCA and GROUND question

[psych0ticnemes1 5,000+ posts]

i have my RCA's running along with my hot wire, i know it's a no no but i didn't know that when i did it... how much of a difference will it make if i run it along the opposite side of the car? is it worth it? i don't really wanna rip everything out and do it unless it is a substancial difference...

also, i have 2 grounds and they both work... BUT is it possible that i'm not getting full performance out of my amp if my ground isn't perfect? i would think that as long as the amp is working i have a good ground but i could be wrong... let me know.. thanks!!!

ABSOLUTELY ZERO

That's a nice old wives tale, though.

is it worth it?

Nope.

BUT is it possible that i'm not getting full performance out of my amp if my ground isn't perfect?

Yes

Only rerun the rca cable if you are hearing engine whine. The ground should be as good as possible for the best performance from your amp.

Still doesn't matter. Alt whine is the result of a poor ground (either amplifier or HU), and NOTHING to do with where the RCA is in relation to the power wire.

any advice on where to put my ground or the best way to make it perfect? i heard sanding it down would help.. i only have really one spot that'll work well...

sometimes my system is loud sometimes it isn't and i don't adjust any settings... have any idea why it's louder and some times and not in others? could if be a grounding issue?

Sand down to bare metal; make sure any dirt/grease/paint/etc is totally gone. Make sure the bolt is tight. Don't use seat bolts, as they tend to not make very good grounds. That's all I can think of right now.........

Possible? Yes. Could be the connection switching between "good" and "bad"....but, it could also be 100 other things.

agreed, hense why i am at a loss and getting very frustrated... i don't understand why it hits wonderful one day, i get in the next, and the subs are moving good, but the bass just isn't the same... i'm losing bass somewhere for some reason.. i guess i won't ever know why

Could just be psychoacoustics aswell //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

and by that you mean it's just me? lol... my friend noticed as well that's why i've been trying to experiment and see what the deal is

if the connection is indeed switching from bad to good, how would i go about fixing that? just securing the ground better? also, i have 2 ground running from the same bolt... good/ bad?

Use a DMM...connect one lead to the negative battery post, and use the other lead to probe possible grounding spots. When you hit upon a patch of metal that reads as close to zero ohms as you can get it - that's a good spot.

Another reason why unibody vehicles = teh ****.

*edit - You drive a Blazer, it should be really easy to find a grounding point in that thing! //content.invisioncic.com/y282845/emoticons/veryhappy.gif.fec4fed33b4a1279cf10bdd45a039dae.gif
