Hey guys! Just installed the Alpine and speakers(specs are below) and at a moderate to high volume I get crackling from all speakers..it is not the speakers blown i know that much..i have messed with custom eq's and everytime i switch one, the cracklinggets at a different volume. the crackling sounds like a cd skipping almost but even with the tuner on. I am beginning to wonder if i have the eq's at quadrants the speakers can't produce or the unit can't. the speakers have crossovers set at 18db/octave if that helps. lastly, will it help if i tone down the tweeters by putting the wires to the -3db setting on the crossovers. help please!!!

Thanks!

I will check all of them tonight. Are speaker wires that are close to power wires always the culprit with a crackling sound. I ran power wire down the driver side and with that wire, my left rear speaker wire...should i route the power wire a different way or is it just wires in the dash that you guys would think would be screwed up. That alpine has a **** load of wires and only so much room to put them in the back of it, should bundle them differently? Let me know if I can track this down futher.
Thanks

So you ran new wire from your cd player to the speakers correct? Why do you have a power wire running to the back of your car? Subs?

Make sure that you got the speaker wires hooked up right on the speakers. Switching them around and putting negative on postiive and positive on negative will cause the problem you describe as well.

Power wire causing interference could be the problem but I doubt it. I have never ran into that kind of problem before.

Just go back and double check that you have everything correct

Brent,
Yes I plan to run subs in the near future.
I am 99.9% positive that all speakers are hooked up correctly, I always double check and plus the wire I use has different shape/texture betwwen + & -.
The only thing I can think of is taht alpine has a modulator for the high voltage preouts. i do not have preouts in yet but it said to put that away from other wires. I have limited room so it is jumbled up with the rest of them. I think i will go in with some wire ties and clean up the back of the unit and see if that helps.
If anyone can think of anything else, let me know!

Brent, you probably have always used shielded cables and wires. Did you 4.6vert? If you didn't then interference could easily be your problem.

I don't even know why they sell unshielded wires.

I don't exactly know. First I pulled the reciever and made sure everything was good back there. I found afew wires that would have become a problem and fixed them. Tried it-noise still there. So i pulled the front speakers, tweeters and all, redid connections. noise still there but occurred at higher volume than before. Irritated, I pulled the back speakers and redid them. While I was doing this I set all four crossovers to the -3 db setting for all of the tweeters. tried it again...voila! noise is gone. i can't pinpoint it yet but redoing alot of it fixed it so my guess is their was some wires that needed attention. I also reran the power wire to the middle of the car to avoid it being by the other cables.

yeah if it was the power wire causing interference, iwould be a whining noise, alot of the time if you run 4 gauge or higher you can get that noise it comes from the alternator. shitty wires will do it good wires are shielded enough
