az73 Posted March 17, 2010 Report Share Posted March 17, 2010 there are two types of spark plugs... resistor and non resistor. i was hoping someone would also chime in cause im not 100% sure, but i believe the resistor type will help suppress engine noise in your elec. system. i thuoght from reading on here that hifonics where desent amps, everyone sure seems to use them. trying grounds from head unit to your amps is easy and cheap. also borrowing/swapping out another amp to see if its your amp would be easy ways to figure it out. my money is still on grounds.

hoppinAltima Posted March 17, 2010 Author Report Share Posted March 17, 2010 I will try grounding up the headunit to the amp ground, but if that doesnt work. will buying a better/ more powerful amp and setting the gains low help with engine noise, as in eliminating it Quote Link to comment Share on other sites More sharing options...
skittlesRgood Posted March 17, 2010 Report Share Posted March 17, 2010 when i had a cheap amp (this is a low level hifonics) the gain affected my engine noise. every quality amp ive had doesnt have any engine noise difference with the gain.

CaptainzPlanetz Posted March 17, 2010 Report Share Posted March 17, 2010 I too had problems solving noise in my speakers, I did everything new grounds, ground RCA's, Ground HU, etc..... but nothing fixed it, then I decided to try a Stinger Ground Loop Isolator and I hooked it up between my amp and my RCA's and the noise was gone and the speakers sound exactly as they did before. You can get one from here http://www.darvex.com/SGN20/Stinger+Ground+Loop+Isolator.html I know it worked for me, and it is only 10 bucks. Quote ¿ǝɯɐƃ ǝɥʇ Trolls never learn............

Thunderthud89 Posted March 17, 2010 Report Share Posted March 17, 2010 Check this site out, I swear by it and it will probably solve your problem.

hoppinAltima Posted March 17, 2010 Author Report Share Posted March 17, 2010 haha ive seen that site, it what made me try turning the gains down. I also did try a ground loop isolator idk if it was because it was from radioshack but it made the whine worse and added a loud hum too. really weird. I think a better quality amp is my best bet. Im liking the RF P400, but are some other good brands?? Quote Link to comment Share on other sites More sharing options...

The ones from RadioShack are very low quality, and actually kill your midbass, try the stinger one, I am about 95% sure it will fix your problem. Quote ¿ǝɯɐƃ ǝɥʇ Trolls never learn............

hoppinAltima Posted March 17, 2010 Author Report Share Posted March 17, 2010 Ok i am going to try the singer isolator. just to double check i hook that up right before the amp? Then there looks like there two wires too, do i ground those wires? Quote Link to comment Share on other sites More sharing options...

Then there looks like there two wires too, do i ground those wires? I didnt have to use em, it fixed my problem just by hooking em in line with my RCA's, they are there so if you still happen to have noise, then you can ground the isolator using those wires. The package comes with pretty good instructions on what to ground to if you have to ground the isolator. Quote ¿ǝɯɐƃ ǝɥʇ Trolls never learn............
