JBL Synthesis Speaker Compatability

[cmw360]

I’m trying to find out if speakers from a 2007 4runner will fit in my 2003 4runner. Both are JBL Synthesis systems 10 Speaker Systems. The Toyota dealer doesn’t know. He said that the first 4 model numbers are the same but the last 4 numbers are not. Said there could be a change in voltage, bolt patterns, etc. Anybody been here, done this?
Thanks!

Recommend you buy something different. Don't go back to factory speakers.
