[QUOTE="Kickstand, post: 8777085, member: 681842"] OK Get the shielded RCA's for sure but if you have a 6 foot ground wire running back to the battery that might be your issue. Ground wire should be ideally 18-36" long. The shorter the better. Do you own a multi meter? If not invest in one. Set it to continuity, it should beep when the two prongs are touched together. Tape a wire, single speaker wire will do (long enough to get from your battery to where your amp is mounted) to the neg terminal on your battery and the other end to one of the prongs on the multi meter Now use the other lead from the meter to poke at existing bolts that are within a couple feet of where you want to mount the amp When it starts beeping you have found your ground FYI- The location I mount my amps in is based on where the best ground is located so if you have to move your location do it Question, if the amp is only 6 feet away from the battery, where is it mounted? Under one of the seats? [/QUOTE]
