What is a good upgrade for the Factory OEM speakers? I do like the factory speakers though I may just buy factory replacements.

 

I'm a old man now so loud music isn't very important to me anymore, but I have purchased a few sets of speakers from the dealership before and was very pleased especially with the price. And depending on the year of your car there may be a Bose option available.

 

I just bought some speakers. The rears that I bought are 4 ohm and the front I bought are 2 ohm. Is this going to be a problem with the factory amp or am I going to have to buy another amp for the different ohms for the spearkers.
