Engine noise/whistle in my components
Ok, I've read some info on what could cause it, but seeking some opinions.
Set up:
03 Honda Civic sedan
Pioneer DEH P3700MP deck
Morel Tempo 6.5 comps in front end, via their supplied crossovers. (crossovers mounted external face of kick plates)
3 10" subs in box in trunk, bridged off of two of four channels of PPI Promos 425 amp. Stinger RCA interconnect run down centre for rear sound. Power run down passenger side to amp in trunk, remote on run down centre near RCA.
Now, I never noticed any whistling via subs, and previous factory speakers were not hooked up to amp. The sound is now heard with the new front end speakers, via crossovers, using a Monster RCA interconnect run down centre same as Stinger RCA, inches from remote on.
Ground at amp AOK. I have this funny feeling it is possibly the remote on wire near the RCA cables. Which will be a bit of a pain to re-run that.
Components are temporary using the last two channels on the PPI, as I was planning on running them solely off of the PG Sapphire.
Any suggestions?
Tim
P.S. System sounds great now, so I'll have to see about coming to some shows etc... Any suggestions on what to do to prevent water in through trunk lid/seal, if bass is full on?
Trunk lid starts hopping up off the seal if I have a good bass song on. LoL

Yup, chances are better than the average bear that you have damaged your cd player. You have more than likely taken out the pico fuse in the ground trace that protects the preamp section. There are three ways to go about solving this issue.
1) the quick fix. Take the cd player out of the dash and take attach a ground wire to the shield of the rca cable where it plugs into the cd player.
2) send the unit for service to have the problem fixed.
3) invest in a Eclipse CD5030 and watch and listen to your system come to life.

This Pioneer I felt is quite a good sounding unit. The Ecplipse are far superior?

Tim, your system will come to life with a Eclipse cd player. The nice thing about selling Pioneer, Kenwood and Eclipse makes for a easy demo in the customers car. It has never let me down. I know that it will bring your new Morel's up to a level of performance that the Pioneer just cannot take them to.
It is a uber small Pico fuse that is not a easy change out. It is generally blown by a bad ground on the amp or by touching the center pin of the rca to ground with the cd player turned on....

Ok, well, no harm doing so, but I took out the pico fuse and soldered a line across in place. No difference. What I've discovered on some deeper searching, apparently the whine is much louder and annoying if pico fuse blew.
Mine, it's audible, but not a ton, and only truely heard with volume down to bare minimum. Something I might live with, although am wondering if these new RCA cables I got have poor shielding and the remote wire is affecting it somehow.
I have a feeling if I go to a different deck, I may still have the sound. Replacing the RCA will be a bitch, but I think that might fix it.

Well, my alternator whine is gone! Seems something related to the front RCA of my Promos amp, maybe not grounded well somewhere with that amp. (rear for subs is ok, no whine)
I hooked up my second amp to run the front speakers last night, and no alternator whine now.
