How long to replace speakers?

[youngmanvr4]

I'm in Houston, Tx right now and my car is in Cali. I'm driving to here (tx) on the 13th and the trip out I found out that my head unit rocks but matched with stock speakers it makes everything sound bad. So before I make the trip I want to replace all 4 speakers. But I'll only have 2 days to pick up the speakers and install them. So how long should I plan on for putting them in? I wouldn't think to long but I just want to see what all needs to be done. If I had my car with me I would look myself but I can't. I dont have to rewire anything do I? Also 4x6 is a rare size, I'm planning on going to best buy and getting them there, what should I get...if I even have a option lol. Thanks for any help, Nate

P.S. this is what I was planning on getting http://www.bestbuy.com/site/ol...22869

As long as the speakers are the right size it shouldn't take more then a 1/2 or so

hopefully you're not going to pay that much.

I bought those same speakers form walmart for $42

How do you like them?

They're alright.

Better soudning the stock, but alot less efficient.

They're 4 ohms, whereas the originals were 10ohms. Yet with the volume knob turned to the same place it's about the same volume.

Note that the 20rms value is a bit higher then what it can really handle. I wouldn't give them more then ~10~15w RMS
