b-dubs89 Posted June 10, 2012 Report Share Posted June 10, 2012 over the weekend i installed 2 pair of alpine type s speakers in the factory locations of my chevy venture as well as an alpine cde-9874 and a 1/0 gauge kit from rf . i ran my own speaker wire for the type s speakers and am running them off a tma 360.2 amp , 2channels at 2 ohms . i noticed after a couple of minutes of listening that i seemed to have some noise , mostly out the tweeters music is less noticeable than test tones , very noticeable with test tones. not so much a like an alternator noise but more like a distortion . i have it with the engine on or off , i tried my old alpine deck and had the same noise , i also tried a ground between headunit and amp and still had the noise . the only thing i can think of is that i do have power cable and signal cables and speaker wire within a few inches of each other . any help would be appreciated Quote Link to comment Share on other sites More sharing options...

b-dubs89 Posted June 10, 2012 Author Report Share Posted June 10, 2012 while i have been waiting for reply i have since tried running only 1 set of speakers off my amp and still have noise , have also moved signal cables away from other wires , still have noise/distortion . would have swapped amp but i don't have another amp so i am now wondering about my amp at this point .

b-dubs89 Posted June 10, 2012 Author Report Share Posted June 10, 2012 where is the gain on the amp set? on the lower side , less than half , my deck has 2 volt pre-outs , have noise at all volumes . the noise is maybe like a fuzziness from the tweeters mostly Quote Link to comment Share on other sites More sharing options...

Pasta Prime Posted June 10, 2012 Report Share Posted June 10, 2012 Do you have noise at 0 volume with 0 gain? If so i would suspect the RCA's or even head unit try RCA's first. If not, amp problem maybe? Quote New build coming........
