it depends on the type of guitar you got bass or electric, any amp will work for Electric Guitar but not all amps work with electric bass.
The best amp you can afford to buy. Will do the job just fine.
Depends if you have a good guitar or not, if not get a guitar if you do get an amp and just buy a new guitar when your current one is not worth having anymore :)
Buy a cheap Jensen amp the 250watt 1.
I have the same problem with my amp. When the amp gets warn out it overheats quicker than when it was new, so there is a safety built into the amp that will kill the speakers so you don't damage them. At this point you should have some repair on your amp, or buy a new one.
800 watt should be fine
Buy an Ipod off ebay. Most are fused I think it is in the back in behind left or right rear panel there should be a fuse in one end of amp.
All you have to do is buy a bypass harness from http://www.installer.com/item/display_item.php?it=70-5513 That should take care of your stock amp.
an amp and a strap
Guitar center
its on sale at best buy
yes
buy a wire kit with thick enough wires for the amp.. It should have the instructions but heres the basics.. thick wire goes to battery from amp and you need to drill a hole through firewall (usually under carpet buy you gas and break pedals) to run it and it should have a inline fuse.. RCA wires go from amp back of radio a wire from amp ground need to be connected to a large metal part of your car. memory wire needs to hook to a power source that's only on when your cars on that way your amp does not kill your car battery when you park. and then connect all the speakers.
