Read The Owner's Manuals and Instruction Sheets.
If those don't tell you enough, find a local expert
(at a car stereo shop) who will help you.

pretty vague so I will make up a situation and hopefully it fits yours. I assume you have 4 mid 4ohm single voice coil speakers and 2 dome tweeters. I will also assume your amp is a 4 channel. Connect the dome tweeters in parallel with the two mids, then connect directly to the amp. Connect the remaining two mids to the amp also. Any other variation of ohms and amp style, this info is incorrect.
