If you are talking about an S-10 pick up the dash speakers are going to be 4x6 and the doors will be 6.5". If it is a S-10 Blazer the same sizes apply for the dash and front doors and the back doors on a 4 door model will also be 6.5" while the back speakers on a 2 door model will be 6x9.
In the doors front and rear.
according to the JL Audio website. A dodge magnum standard SXT or SE setup has six speakers total. on the dash it has two 3.5" speakers; 6.5" speakers on the two front doors; and two 6x9" speakers in the rear.
5 inch is the biggest you can go on a standard door fitting but if you reach in yo pockets and mod your doors you can go large as you like
2 front door speakers 2 tweeters in front doors 2 rear door speakers
Front & Rear Doors take only 6x8 speakers
Standard Sedan DeVilles had 6 speakers; two on top of the dash near the windshield, two in the front doors at the front lower corner, and two on the package shelf near the back window.
There are 6 speakers in total; two rear speaker located in the doors, four front speakers; two in the door and two tweeters near the airvents next to the front doors.
