OEM speaker sizes on 2008 F-150 ext cab

Go to the Crutchsfield catalog on-line and look up your car and it will show you and specify good replacements that fit. Their new interior door panel liners are also very good.

Bose Amps Are Very Propriatory ie: wire very Different, with special ends--They Can Be Replaced--However Will Cost More Than Worth--You Can Get OEM Amp From Salvage Yard--Which Is Much More Cost Effective. If Bose Speakers Are Present. Sound Quality Will Be Very Poor Or Nil If You Bypass Amp.

There is only one rule when you replace speakers - never buy a lesser powered speaker than the amplifier. Size is determined by the space that is available. The bigger the speaker the better it will perform and will be more efficient than a small on -- jut like a ceiling fan.

Yes , you can replace the 15 watt speaker with the 50 watt speaker. The impedance of both speakers (4ohms) is the same , so that's a match. Actually, the 50 watt speaker may sound a bit better at higher volume, because it will not distort as much as the 15 watt speaker. Hope this helps...
