OK, I will attempt to make my problem clear I am running 6.5 components in front bridged to 6.5" woofers in back (Crystal CS60C), Boston RC620 respectively, off of a 2ch clarion amp. For subs I am running 2 10" JL's off of a 4ch amp (this configuration nets me optimal power distribution...don't reccomend I run the subs off the 2ch because I have done it before and it is either underpowered running individual channels, or it goes into protection when bridged. anyhow, onto my problem When the volume is approx 3/4, powerful enough bass thumps will cause a crackle in my passenger side tweeter (front). When I turn the subs off, this problem dissapears, and when i turn the speakers off, the problem is also gone, so it is a result of running both amps at once. My theory right now is that there is some interference between the sub wires and the speaker wires, and at a high enough power, this is resulting in my crackle. I have no alt. whine in the speakers so this isn't a grounding issue, and I'm running 4awg power wire, so I do not think that this is a power issue. Any suggestions would be appreciated.
