Buzz sound in rear speakers

[darksparkz]

I switched out my front 6.5s to CDT EF-61 components w/ 1" tweeters, but I left the rear 6x9s stock. I have a Alpine HU on and a Aura amp to power the front speakers, while rear speakers are hooekd up to HU. There is a weird buzzing sound on the rear 6x9s at certain parts of songs. It also happens when the radio is turned on to a talk show, you can hear the continous buzz. Is it just because that the rears are pretty bad compared to the fronts, so you can hear the buzz?

I had the same issue with my Honda Civic speakers in the front doors. The speaker wires were touching the metal of the door (they were being grounded) which caused the buzzing.

Double check your install and make sure the connections are not touching metal.
