Superultrahippo's mini audio build

[superultrahippo]

I borrowed a cheapo amp from a buddy and hooked up power/ground/remote.. Doesn't do the same thing. In blaming it on the amp and returning it. Any recomendations from sonixelectronics dOt com???

It sounds like an earthing issue to me.

Make sure that the antenna is earthed properly to the car via the head kit and the earth strap from the antenna it's self.

There is on some antenna's a small o-ring that deteriorates over time and it earths out to the wrong part of the antenna body creating an earth leak and causing you bad reception when you hook up the amp earth cable.

As a precaution run the Head Unit's earth straight to chassis earth, bypassing the the loom and check the earth strap from the engine to body.

Is the amp remote turn on connected to the power antenna trigger by mistake?

I double checked and have blue/white from head unit and am using that as my remote. BLUE(HU)-WHITE(car harness). According to my manual.. that's correct.

my amp wasn't working when I initially hooked it up. So i put a voltimeter on it and turned out that my 8 gauge ground wire wasn't big enough + it was a bad grounding point. I dunno if it'll work for you but just put a meter on and see if you get 12+ volts...

Also on one of the amp pictures i think i see the "diagnostic" light on, not the power???

That's how my amp was before I got a bigger ground wire...

Were you having the same FM reception symptoms? Ill get my meter from work tomorrow and check it out.

stumped.

Hey luke, I have a factory amp. Could this have anything to do with it? I have all 4 speakers wired from the fader. It's not alternator whine. It sounds as if I have REALLY shitty FM reception.

[superultrahippo]

Well, im all out of ideas.. RCA's aren't even connected and it still happens. As soon as I disconnect the ground from the amp(turning off the amp) reception comes back. Reconnect---goes away. Connections are good and away from interference. I snapped some pics of the set up as of now. Any ideas? ..bad amp?

[superultrahippo]

Wait...did you put the amp near the antenna?

No, the amp is on the lower right side of the backpanel..

[superultrahippo]

Ran RCA's in clear way from antenna harness.. still get static on FM/AM. Goes away when I take out the AMP. Im running out of ideas..

It get better.. Reception comes back if I disconnect the ground from the AMP. I eff'd up the crimp connecters supplied in the amp kit so I had to do away with them and hook up the 6g power/ground cables directly to battery. Im guessing this has something to do with it?

[superultrahippo]

Almost done! ..my FM reception went to crap though. Checked for loose connection and found all of em ok. Even the trunk one. Antenna extends and retracts.. grrrrr!!!

Set "Level" to 95% of maximum.

Set "Low Pass" to about 75 80Hz at 12db/oct

Do NOT use bass boost until you are used to this: that is a woofer eater in your case.

"Subsonic" should be about 20Hz unless you are listening to a bunch of hip hop, then like 25Hz.

You should have pretty major thunder with that.
