Alright, I'm going to try and not flame ya but there is a TON of information on this forum about your number 1 and 2 problems.

But if your not sure what your looking for then here's a little more info. Basically the reason why you have sound comming through your speakers is because most likely your speaker wires are close to a ground... (consider buying a ground loop isolator) or re-locating your speaker wires or ground wire.

2, the thump your getting is from your PC's sound card. There are startup controls / DC-DC regulator such as the Carnetix 1260 that have a delayed amp turn on feature... basically this turns your pc on with the ignition wait a few seconds then turns your AMP on, this will get rid of the thump.

in Response to your 3rd question... Your not touching your ignition are you ?? If so leave that alone !!! you will find an ignition wire or accessory wire that turns on with your ignition attached to your radio... use that... don't rip your ignition apart...

"Wires close to a ground"? The whole chassis is a ground, you'd do well to wire up your speakers without the wires going near any part of your chassis!

I would suspect that it's a bad earth, ground loop isolators are pretty much a last resort for car audio.

also, be careful about going to an auto electrician if you choose that path, i did that to get my inverter installed, thinking that someone "in-the-know" would do a good job, he just took the accesory wire from the steering wheel column and ran that straight to the inverter and shoved a 40 amp fuse in a 15 amp circut!!!

as for the car noise, try an sngine noise surpreeor and keep the power cables on the opposite side of the car to the audio cables, works for me just fine
