Hey guys i got a problem.

1st. I have a stock stereo i havent had the chance to change anything the only thing new is the head unit which im bout to get rid of cus it sux. But anway my first problem is whenever i drive i hear this sound when ever i accelerate i looked and everything is grounded right so i dont know what the problem is.

2nd. Once in a full blue moon my back speakers decide they wanna work. I checked the wiring going from the headunit to my power harness and everything is intact and the way its suppose to be. But for some reason i get no sound out of it. The weirdest thing happened last nite. I get into the car and started it up and the back speakers worked so i drove home (bout a half hour) and would hear this scratchy noise coming out of the back speakers. So i got home turned the car off and then turned it to the point the radio just came on and my back speakers were no longer working. Like i said my speakers just comes on when they want to. Do u think i need to replace the speakers or do u think its a wiring problem or a problem with the actual head unit.

3rd. Im gonna shave my antenna off so i was wondering is there a better place to put the new antenna that im gonna buy.

4th. If anybody knows of an easy way to take the speaker cover off so i can change the back speakers then that would be greatly appreciated even a comment on a fast way to change the back speakers would be great.

Thanx
Jae
