couple of questions

[espguitarist91 10+ year member]

A couple of weeks ago i installed my amp (hifonics 1606d) and right away i heard a static noise. Im not sure what it is. Its pretty loud, but not noticable from the cabin with everything closed. It happens when the car is off too, so i dont think it can be alternator whine. Maybe ground loop probalem? I tried grounding the amp in a different spot, but no difference. Both spots were bare metal. Power wire and rcas are on different sides. I read the sticky, im just wondering in anyone else has a common problem and a fix.

Also, the surround on the sub(PG RSD 12) is coming off the cone on some parts. Can i just super glue it back together?

Thanks

what headunit are you running? try regrounding headunit and grounding the rca's. could be a bad amp

I have a kenwood 632u.

i think ill try grounding the rcas, but i havent heard of kenwoods having that problem too often. I have scosche RCAs, that may be part of the problem. Ill try it off another source like an mp3 player to check tommorow.

And about the sub, will super glue work fine?

I would say it might be the RCA's. The first system I had relied on Scosche RCA's and they ****** up noise real bad.

- for the surround problem, IDK what to tell ya, never ran into it. Where did you get your subs from, maybe a warranty?????? I just don't know. Was looking into a pair of them, and hope they don't do that.

try grounding the amp directly to the battery, if the noise goes away, you know it was then a bad ground.

are they're any metal rings or cosmetics on the rca tips?

Ive got some rcas that have that, and if they touch at all you get the same thing...

just remove them or tape over them..

(I think Ive seen some of the scoshe rcas with that before)

Well, the noise is still there even when the rcas arent plugged in. I guess its down to bad amp, bad ground, some other interference.

have you tried mine yet.................ground the amp right to tha battery, and if the noise goes away, then you had a bad ground.
