[QUOTE="1aespinoza, post: 8832212, member: 654802"] Atoto and similar make radios are not known for sound quality. So noise should be expected when buying these units. The loudness is because the OEM radio does not have a built in amplifier, so it sends a low signal to be amplified. Your Atoto does have a built in amplifier and the RCA outputs may be amplified. Check the radio settings to see if that is an option. The decision to use an LOC is your best bet. But it is better to use an active LOC for they are good at ground noise reduction. I have recently used the Digital Designs SC2 with good results. If you want 4 RCA inputs/outputs, then the SC4a is your best bet. [/QUOTE]
