You need to pull a dash speaker and take a look. You might be able to get more volume by going to a speaker with greater sensitivity. Don't know the sensitivity of the stock speaker, so will be trial and error. You also need to determine the impedance of the stock speaker. The Bose units seem to be mostly 2 ohm. Non-Bose, I don't know, but would guess 4. There are some speakers out there which are sold as 2 ohm, but are really closer to 3. Those you might be able to use in place of stock speaker without overheating the stock amp. Lower impedance speakers will play louder. An amp rated for a 4 ohm load will probably be ok with 3, but I would not try a 2 ohm load. You will gain volume if you swap high impedance for lower, lose volume if you swap low impedance for higher.
The other thing you need to check when you pull the speaker is magnet size. Not sure how much room there is. Some aftermarket speakers gain their efficiency partially through bigger magnets which means a stringer field. You can also get that through stronger magnets like neodymium.
