2001 Grand AM Build

Bought a RCA ground loop isolator in hopes to solve the hum/whine from the front speakers. It didn't change anything

Didn't get a chance to check the RCA's behind the HU yet.

yeah, they only mask the problem anyway. i would check the rcas and get rid of whatever you have on them, maybe their causing it, try it without them.. also try wrapping them tight and in a few layers of electrical tape. thats one thing i did to solve mine

I got antsy and assumed the ground loop isolator would solve the problem because because it fits all of the descriptions.

Very stupid decision. I got all my money back though, so all good //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Started the amp board today. It's coming along nicely i think.

Still have the speaker whine, it's not from RCA's grounding out behind the HU, i swapped them around and it just made it louder. Ground loop isolator didn't work either.

Now I realized there is a hiss on high volumes on songs that have spots with no music. =/

need to cut the amp holes a little bigger, and straighter //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

and thats gonna all be mounted down.. right? including the amps, crossovers and the amp rack?

 

[BeAlLsTaR13 10+ year member]

just thought of something..

what are you using as your music source? aux input? i know on mine, that when im using my aux input with my ipod, with NO music playing i get that fuzzy type noise, only when no frequencies are being played..

maybe it's the same case for you? ive never noticed it if i used CDs.. i'll check tomorrow to see if it does it with CD's too, but yeah same thing happens when i use my aux output only when volume is up (isnt audible when volume is lower than like 20 on my HU)

Some more was done to make them straighter but i didn't get to take any pics of it, the jigsaw didn't like to cut straight at all. Also it isn't that the holes are crooked, the amp was crooked because it's not mounted.

It's not going to be mounted because it will all be mounted to the amp board which is snug in the trunk and will not be moving anywhere.

Ipod cable, not aux cable. I'll try the radio tomorrow but i don't think it will make a difference.

It does it on the radio also. And I don't have a CD player lol. Alpine HU that cost me $350 doesnt even have a CD player.

my ida-x100 did the same thing but the ground loops fixed it =/

What ground loop? loops? I got that one from radioshack because Bestbuy didn't have any

Everything is pretty much done, I might cover the holes with glass next weekend, I haven't decided if it's worth the time yet.

Still have the whine in the speakers lol, but I'm just trying to tune it out of my head lol.
