Trâgîk Posted March 10, 2011 Report Share Posted March 10, 2011 I got my RF T1 series comps in and there Is a buzzing or humming noise that comes from the speakers when i plug the rca's into my 4 channel amp. I thought it may be the grounds from both amps grounded to the same battery ground so i moved the 4 channel ground to the chassis and it went down some but its still faintly there. I moved the rcas so they werent near power and still there. Any ideas guys? Im using a 4 channel LOC to go to both amps Quote -----SELLING EVERYTHING---- 2 DC sound labs 3.5k's (still avail) 2 HDC312A D1's (still avail) 5 XS Power Batteries (1 d3400 and 1 d1200 left) 4 runs of knukoncepz 0 gauge (have all the wire still) DC power 270XP alt (sold) RF T1 6.5 components (both sold) Powerbass XAX 4160 (still avail) Custom built box 4.75^3 tuned 34hz (still avail) Link to comment Share on other sites More sharing options...

Trâgîk Posted March 11, 2011 Author Report Share Posted March 11, 2011 What LOC did you use? Its a david navone engineering 4 channel loc. It works pretty good, but i think i may have wired it wrong, what i did when i wired it is combined the front and rear left channels together and the front and rear right channels together, do you think that could cause the noise?
