[QUOTE="75MonteCarlo, post: 1453855, member: 556815"] Ok, i've been working on my own system for quite a while now, posting on here, lurking, reading, learning, and i thought I had a pretty good idea of what i'm doing, but I guess not. See if you can figure out what my problem is here: I'm getting alternator whine and signal noise through my speakers. The speakers are distorting at lower volume than normal, and doing so in tone with the bass beats. I've got a 2nd battery in the trunk, as a way of grounding all of my electronics directly to the battery to eliminate noise. My rockford amp along with 2 caps and my speakers amp are all grounded and powered off of the rear battery directly. The ground point on my battery is grounded to the frame and the ground point has had the paint ground off so that it was shiny metal to ensure good contact. I ran 2 seperate pairs of RCA's from the deck. The sub pair on the power wire side of the car, the Speaker amp pair on the other side of the car, away from power wires. When connected, I had bad signal noise. This was before the addition of the second battery. After putting in my 2nd battery, I then used the pair of RCA's that are run away from power wires to feed signal to my sub amp, and used the pass-thru on my sub amp to connect RCA's to my speaker amp. Are you with me here? RCA's go Deck--->Rockford T10001bd--->Clarion 2-channel speaker amp. Power goes: Front batt--->rear batt--->0.5 farad cap--->1farad cap--->Rockford T10001bd The clarion is powered from the rear battery seperately from the rockford. (not connected to the capacitors) My experience has been that when I use seperate RCA's on each amp I get bad signal noise, but when I use the pass-thru from the rockford the signal noise isn't as loud. Seeing as everything is grounded to the battery, would it be better to ground the Sub Amp and caps to the chassis, and ground the Clarion speaker amp on its own on the battery? **** I can't seem to put this into words that make sense.. anyhow I hope this is legible, maybe someone will see the problem. Ground issue? bad amp? bad deck?[IMG]//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif[/IMG] [/QUOTE]
