geordie_aaron Posted June 20, 2005 Share Posted June 20, 2005 aah, cant remember the name for it but in short its interfierence (spelling) check your HPF's and LPF's are turned on correctly check your RCA's to the HU + amp and finally check its earth correctly Link to comment Share on other sites More sharing options...
Mart Posted June 20, 2005 Author Share Posted June 20, 2005 cheers mate,i checked the rca both ends last night and all seems to be ok. might be the earth wire then coz the hpf and lpf havent been changed. Link to comment Share on other sites More sharing options...
geordie_aaron Posted June 20, 2005 Share Posted June 20, 2005 also maybe the quality of the CD/MP3/tracks if they aint upto much they maybe making their own notes lol Link to comment Share on other sites More sharing options...
j4ffa Posted June 20, 2005 Share Posted June 20, 2005 i know it sounds stupid but sum times its because the rca cabels arnt on the right way i had that problem ages ago turned em round n sounded sweet after that Link to comment Share on other sites More sharing options...
Mart Posted June 21, 2005 Author Share Posted June 21, 2005 yea tryed that craig,i thought that may be the prob but nothing has changed,it just happened. ive taken the whole thing apart, tryed cds,everything,and its still happening. Link to comment Share on other sites More sharing options...
geordie_aaron Posted June 21, 2005 Share Posted June 21, 2005 DEFO interference then....just got to find from where then... turn sound system on WITHOUT ignitionWITH ignitionWITH the engine running see what happens then..... if it happens with all the above its either a earth OR......sumit wrong with the amp/sub (last legs) if its intermittent with the above then its going to be sumit with the alternator if the engines on and you'll need supressors fitted (NOT worth the money) Link to comment Share on other sites More sharing options...
Mart Posted June 21, 2005 Author Share Posted June 21, 2005 i cant turn the system on withought ignition on,lol. ive tryed it with engine on and off and it does it still. worst thing is when i change song and it makes a thump thump. Link to comment Share on other sites More sharing options...
geordie_aaron Posted June 21, 2005 Share Posted June 21, 2005 EH you can't turn the system on without ignition? thats crazy, just turn it once and wait a second...... sounds like sumits on its way out........try different RACs, but go to halfords/electrical place round your way and get them to test the amp out sounds lik its JUST turning off then back on ?!?!?!
