[QUOTE="martiandancer31, post: 7607414, member: 616516"] play a test tone through your HU and turn it up a lot....then test your RCA outputs with your DMM set to AC voltage. If you can, measure the frequency as well and see if it lines up with the test tone. also, go ahead and check your RCA's for DC offset....why not while you're at it. [/QUOTE]
