Default Woofer Feedback in 01 TJ

So my TJ is having some engine feedback through the factory woofer in the center counsel. I think it may have happened after a spark plug changed, but I am sure I used Champion plugs. Anyone else have this problem? You only hear it at idle. Raise the RPMs and the noise goes away.

Plug wires will cause this if they are poor quality, or if the sheilding is bad.

my family used to own our own repairshop, we refused to stock champion spark plugs because we had so many complaints about them...we heard about things like this all the time...monkeyevil is correct. your wires might be cross fireing, try to reroute them or put wire loom around them

Well, that is good input, but this ain't got those plug wires. It's an ignition rail system, because it's an 2001. So, still may be the plugs then.

Ground issue with the sub ?

Just another option if the plugs dont fix it.

Never had a problem with Bosch's or NGK's. Ever think about the fact that both of you might have gotten the wrong heat range for your vehicle by accident?

No, Bosches had a bad run of plugs for a while. The electrode tip was falling off and scoring cylinder walls or buring up valve seats. By now I am sure they have fixed that problem with their platnum plugs, but I will probalby stay away from them.

Anyway, anybody else have any new ideas for this probem? We have beat to death the spark plug issue.

beef up the wires on your alternator(hot and ground), somtimes amplifers (even factory amps, and the ones built into radios) can pickup noises from your alternator

My 03 tj came with champions from the factory, and I didn't have any problems like that, ever.

I HAVE had problems with the factory cd player, and the sub. Both have been replaced twice. That option was a waste of money.

We've been through 2 radios in this thing, but not a sub. What happened to your sub?

They sounded blown, and the dealer said they were blown.

I don't listen to any really bass-heavy music, but if you saw one out of the console, you would see how flimsy they really are.

Since I ordered my jeep, it still irritates me to this day that I dropped the money ($350, I think) on the "350 watt 7 speaker premium sound system". The truth is, it really only puts out about 80 watts max, and 50 of it is sucked up from that shitty 6.5" sub.

Your run of the mill $100 basic pioneer CD deck is years ahead of the stock CD deck. Same goes for any basic 2-way speaker you could buy. All that adds up to way less than the factoy stuff, and sounds a ton better.

Well, I only hear it through the sub, and it's not your normal whiny feedback, more like a sta sta sta sound. I've changed plugges twice with no luck. Maybe I'll just check the ground and maybe put a filter on the factory amp power wire.
