2007 Camry (Gen 6) speaker replacement

[gatoflaco]

I have a 2007 Camry LE with the JBL 6 CD changer with 8 speakers. I like the head unit and JBL amp, but I want to replace the rear speakers. Does anyone have a recommendation? Has anyone replaced the factory rear speakers? Later on I may replace the door speakers. I'm thinking better 6x9 or other sizes.

My question is about the crossover frequency. I noticed the factory speakers in the rear have 2 sets of wires for each speaker. The tweeter and woofer are wired independently. I’m assuming the JBL amp mounted under the passenger seat is separating out the high and low signals, and then sending them separately to the tweeter and woofer. Can I get a set of component speakers with crossover and just not use the crossover? Or a pair of component speakers that can be bi-wired?

i just purchased a used camry se with the JBL premium 8 speaker system. 6 speakers, 8 different drivers. replacing the speakers is not as simple as it sounds. you must remove the back seat to get the rear panel out, along with the the side pillar covers. this is just the beginning of the problems. the rear jbl speakers are component, with the crossover points done in the under seat amp. i do not know the xover frequencies. the 6 disc changer jbl head unit uses serial bus digital signals to feed the amp. so adding an aftermarket amp is a chore. you will need a line ouput converter, audio control ls6i or similar. this converts the post amp speaker signal to an rca preout signal to feed a sub amp and main amps. i stole the signal from the rear speaker wires while i had the seat out. the jbl amp feeds the rear speakers a high frequency to the tweeters and a low frequency to the woofers. took a while to figure out what was what with that issue. no prints or anything on line without paying $. i fed the left and right high signals to input 1 and the lows to input 2 of the lc6i. used the signal summing to get a full range signal to feed my amps. to just replace the speakers is a gamble , betting on the sound will be good with jbl amp xover setting to match your new speakers, which would have to be component, not coaxial. to just add a subwoofer, as i was only intending on doing, is a major task for an amature. luckily i am an audiophile geek with tins of electrical experience. use critical mass ss69 6x9 speakers, and the xover frequencies of the jbl amp will match very well with these speakers, if you don't want to add good amps and such. these speakers are coaxial but are biwire or biamp capable, i got a set on ebay for 160$. long story short, go all out or just stay stock, or replace everything stock and loose all the goodies like aux input, steering wheel controls, bluetooth, and all that. it is all ran by the jbl system. GOOD LUCK!!!!!!!
