So, I am replacing my stock stereo, and I have run into a couple of problems. Here they are:

1.
Old stock HU = Great reception on 99% of FM stations.
New, Sony GT520 HU = Mediocre reception on 50% of FM stations (sounds like a 'crakling' effect - TERRIBLE)
What can I do???


2.
Now recieving slight 'whirring' sound through speakers as engine spools up... Just installed MTX Thunder 340 Amp. Sounds like a noise filter??

3.
Having trouble mounting rear 6X9's. The mounting holes don't match up. Speakers are Infinity Kappas. Any ideas???

4. OFF TOPIC: One last thing... I think the front struts may be dying. Car pushes and pulls on the freeway pretty bad. And I hear a clunk from the front-left when entering driveways, holes in the road or aggressive breaking. What do you think???

Talk to me!!

1. make sure the connection to the antenna on the back of the new HU is in correctly

2. I get that too, possibly the wires aren't shielded well enough, or even the HU itself isnt

3. had same prob w/ 6x9s just drill new holes, that's what most guys who work audio installation would prolly do

4. get new front struts
