Answer 1

Ant car stereo you buy in a store - hence aftermarket

The problem is someone told you wrong. You don't NEED a new deck, but it would help.

You REALLY need an amp to push those.

Answer 2

Aftermarket is anything you buy for your car not made by the manufacturer.  You don't really need to go aftermarket.  You can get a HI/LOW converter from anu stereo shop and still hook up some amps to your deck but you won't have the control of the sound that a good aftermarket unit will give you.

Answer 3

Simply an aftermarket stereo(deck).

You DO need one, simply to make it SOOO much easier to hook up the 250 watt (min.) 1000 W. MAX. 2- channel amplifier to push them !
