Before you buy your speakers, you need to make certain which size speakers your vehicle has. You can simply search the type of car you have and can locate fairly easily the answer.
If you're planning on making use of your factory CD player, be sure not to purchase over powerful speakers. Your in-dash receiver that came with your vehicle will never supply enough power.
If you do desire to use powerful speakers, you are going to need car amplifiers. You may either replace only your front speakers and leave the trunk powering from the deck, or replace all. If you replace just the front, you will need a 2 channel amplifier. Should you replace all, you'll need a 4 channel amplifier.
You have to make sure that the RMS power output on each channel from the amplifier matches as close to the RMS power input of each speaker. Why? Since this is the way it needs to be. Don't under power or overpower your speakers.
If you're going to add a subwoofer or a set of subwoofers, you will need to buy an amplifier to provide them lots of watts. Just one subwoofer setup usually supplies enough bass for the whole system, even if upgrading all four speakers and using a guitar amp to power them.
A decently powerful 12" subwoofer will hit hard for rock music and also produce lower and deeper bass for hip hop and rap. If you are using a pair of subwoofers, you are most likely likely to create double the amount bass.
