yung nga, sa fm kasi kaya siguro me engine noise. nung kinabit kasi yung lumang HU wala daw video in out kaya sa fm nilagay. necvox na dvd ceiling mounted. yung HU ko ngayon na alpine cdm7871 ang hirap mag hanap nung DIN connector, kaya eto ang ingay pa rin pag nanonood kami

FM modulator po ba ginamit? malakas talaga interference pag FM signal!!! better get a HU na may audio input and iwasang magkadikit yung RCA and Power cables

Check the ground in your head unit.

There are may kind of noise.

1. Engine noise- in any Amp installation, particularly one that involves multiple amps, electronic crossover or equalizer.

2. Noise in the Pacth cord- in many instances, noise is picked up by the RCA patch cords connecting your components.

3. Noise pick up by your Antenna or Power cable- if it is not coming through your the patch cords the noise maybe coming in through your antenna.

4. Radiated noise-Check metal housing of your receiver isnt touching chassis ground.

5. Noise in the Speakers- Shield them from radiated noise or move the speakers as a last resorts.

6. Noise from Electrical- This problem could have been anything. From Battery, alternator, ignition noise like tickling sounds, spark plug, spark plug wire, distributor cap, Coil, you may need tune up and other items such as Air cleaner, your hood, your exhaust system etc.
