He is running speaker wire to the amp.... Really doesn't matter which end signal comes from it has to connect at both points..

 

[Undead Rado]

If anyone on here is dumb enough to run signal from the head unit speaker wires to the amps output connections they shouldn't be installing anything to begin with lol

 

[darvoh]

Wow you are getting technical, apparently I'm not using the correct terminology but yea that's exactly what I meant. Using the stock wires and running them back to the amp so they are getting the power FROM the amp how's that? Lol

My brain keeps visualizing the signal feeds when you say running wire to the amp.

When I think for a second I of course know what you mean....but it's not following the current path in that direction. I know, mr. technical. Then again, I get paid to make sure I know which direction things flow - so I'm notice things that pretty often. My job has definite to's and from's.

 

[Undead Rado]

Lol no there are a few internet gurus with very little experience but lots of time to fill their head with info that they often confuse from lack of applying it

Finally found the time to go through and install the new Rockford Fosgate 250x4 amp! Install was a breeze, decided to not take the time and run new wire from the door speakers to the amp because I didn't want to deal with the door boots. SO its a simple setup taking the existing speaker wires and wiring them back to the amp. Of course making things look clean in the process hiding the wires lol Also the amp is finally giving the speakers the juice they needed so no more clipping :th_woot: Overall I would say this amp made a world of difference on sound quality, like being at a concert. However for them being 6.5" door speakers obviously the bass isn't by no means incredible but I am impressed with these Kicker CS54's. Didnt feel like installing the FatMat today so saving that for the weekend probably when I install an Alpine MRP1000 amplifier for the final sub touch to make it sound beast :drinking28:

Now I'm just dealing with the dreaded alternator whine, any tips to rid of this? Ground Loop?

 

[Undead Rado]

RCA's and power wire ran on separate sides or truck? If so where is your ground? A ground loop is basically to cover up of an issue. I have ran 1600w rms to highs alone with clarity

Yea the power cable and front left, rear left wired down left side. Both sets RCA's, Remote and front right, rear right wired down right side. I just grounded a short wire to one of the rear seat mounting bolts, convenient.

 

[08Canyon]

Is the ground cable the same gauge as the power feed from the battery? It's recommended (from what I remember from 25 years ago), the shortest possible ground wire, and same or heavier gauge as power feel make for a good ground.

 

[Undead Rado]

Most of the time I have had the issue it has been caused by the ground, but I have grounded 2 batteries and about 3,600w to only one seat post bolt with no interference. RCA and ground would be the two things I would check, if all else fails stick a wire to ground and the external connection of the RCA and see if it stops it.

 

[darvoh]

Thanks Undeadrado for the reply. The RCAs, speaker wires and remote wire run down the right side and power cable is on the left side. I tried touching the ground to the RCAs to see if it would stop and the speakers made a louder whine noise. Not sure what to do if yea have any more tips. All wiring is clean, thanks.

Did you pull hard on the rcas to get them under the carpet or anything like that? Idk what brand wiring it is but I would buy cheaper wiring kits but the rcas would suck so I would get rcas separate and just use power and remote from the cheap kit.

 

[darvoh]

Undead- still trying to figure out how to fix the the wine and I've narrowed it down solely to the RCA cables or RCA output/ inputs. Reason being if I unplug the RCAs from the headunit or amp no wine, plug it back in the wine is there. So I bought brand new RCA cables and sounds exactly the same. I purchased an Axxess inline noise filter, wired it black wire to ground, red wire to positive battery, green wire to remote and didn't do anything. I'm stumped, tried grounding the RCAs on the headunit and that creates and even louder wicked noise, was quiet for a while but the headunit was getting super hot. Any ideas would be appreciated, thanks!

sounds like its the head unit itself

 

[08Canyon]

That a lot of wine. Maybe the stereo system is drunk?

Good thing you don't experience whine. That would be horrible! LOL

 

[scott33mull]

If I have had whine in the past, I run a ground from the radio chassis to the same spot the amps are grounded and that has always seem to fix the issue. Had good success with this. A stereo installer way back when told me that and I have done it in the past.

I have a small whine in my current system I just finished and didn't do the ground that way, going to switch it tonight and see if it fixes it.

 

[darvoh]

Let me know Scott I would be interested in knowing if it fixed the whine! I did run a ground from the chassis ground behind the headunit to the negative on the amp which reduce the whine but it's still there.

Much appreciated, thanks.

Prime series amplifier squeals or causes engine whine

This might help. Mabey a grounded speaker wire...
