eto story..

1. had v12 f-805 driving my separates and 6x9 coax
2. had mtx rt404 driving my subs
3. static busina and static sound pag nag-re-rev

here's what i did...
1. used v12 to drive subs, then used mtx to drive separates and 6x9.
2. tanggal static pag-nag-re-rev pero nandun parin static pag busina

already tried the following:
1. checked ground ng busina (move around sa chasis, engine, etc.)
2. lagay ng ground sa DSP unit
3. installed Y connector sa rt404 amp (meaning wala ng fader), humina konti static sa busina pero lumakas static pag nag-re-rev
4. used condenser to ground yung busina

HELP!!!
