2010 Camry JBL Amplifier Question (Subwoofer Install)

[Dunk7]

I cannot find an answer anywhere. Not from JBL or Toyota

Background:

I own a black 2010 Camry SE with the JBL sound system.

It has a 440W DSP JBL amplifier installed from the factory under the passenger seat.

I am aware that DSP amplifiers are very unique in that they perform most of the controls related to the audio system as opposed to the head unit. They also have highpass and lowpass filters onboard in order to send the correct signals to the appropriate speakers.

I am getting ready to install 2 10" subwoofers and a 1200W Amplifier (toned down to avoid changing alternator that only puts out 100A)
(2) Boston Acoustics G510-4
(1) Kenwood KAC-X1R

I am planning on just hooking up to the outputs directly on the amplifier to avoid having to splice cables and keep my warranty as intact as possible. This is where my question comes in.

Question:

What frequencies are passed from the amplifier to the stock 6 x 9s? I cannot find this information anywhere. If they are not recieving the very low frequencies then there is no point in passing that signal on to my subwoofers.

I have a MTX Re-Q that is meant to bring back the bass that is many times
reduced in stock headunits to avoid damaging factory speakers, but if the signal is completley gone through the use of the filters in the amplifer then even that won't be able to bring it back.

I know that forum member Bigtuna was able to hook into his 6x9s in order to feed his subwoofers, but I don't know if he was getting the full desired signal.

Any help is greatly appreciated.
Thank you in advance for looking over my question.

Welcome, I'm curious about this answer since I'll be doing the same soon but I have Navi.

Did you just buy your SE if so did it come from Bert Wolfe? I recently bought mine and was going to go through Will at Bert but he couldn't give me what I wanted for my Altima coupe so I had to go to Love which at the time had the only SE in the state besides the demo white one at Bert. I just drove by and saw that the black one they just got in is gone. Sorry don't mean to thread jack

No, I got mine from Advantage Toyota in Barboursville. My cousin works there. I put a down payment on one they had coming in and got it the day it hit the lot. I barely made it within the window to get 0 % interest for 60 months. I love the way the all black SE looks. I got black leather inside with moonroof and JBL package. Trying my best to keep it clean. haha

Yeah we were going to get a black on black until we saw the blue plus like I said it was the only one in the state at the time. The one at Bert was cloth interior. I'm in bville all the time maybe I'll run in to you. We couldn't get the 0% since it was a plant deal but it's still cheaper in the long run.

Their are multiple threads about that topic (just now, one is going on). Most simply splice/connect a LOC into the back 6x9 and not even use a cleansweep or similar. The rears give you enough of the low frequencies (maybe not for a purist, but good enough for 99% here). I have the JBL and did just that and it works great.

[morgaman]

i just finished an install with an MTX jh600 amp and used an LOC at first to get power. this was because I had gotten mixed reviews people on both the LOC and the speaker level inputs on the amp. in my opinion, the LOC worked amazingly well and was simple too. my only problem with them is that i like to play with the audio function in the jbl system, and frequently moved the sound selector from the middle to the drivers seat and back (im talking about that front-back-left-right thingy to the right of the equalizers). my loc was attached to the right side and i lost a little bass when i adjusted the selector to the drivers seat. the amp came with two speaker level imput wires so i saved the extra ~30 bucks and used them, one cable for the right and one for the left. im sure 2 LOCs would work just as fine

I'm also not sure where the JBL amp cut off the bass. I know that on the avalon, jbl claims a range of 20-20000 hz. im sure the distributed bass in the camry is somewhere between 20 and 50 hertz, because that is where bass becomes audible for humans. I'm considering trying to find a frequency cd to accurately test the cutoff ( anyone with a RF amp or some JL amps wanna help us out )

I highly doubt that the jbl system is going to pump out tremendous lows (there no shot in hell of hitting that 5 hz limit on your amp) but with your subs having a 24 hz cutoff you should have no problems

Just splice off the rear speakers. That's what I had an audio shop do for me several years ago. It's been great and the amount of bass is not affected by me using the fade control.

I know this post is a little old, but can anyone provide pics of where they sliced into the rear speaker wires? I have an 07 Camry SE with the JBL stereo. I'm looking to install a sub and amp that I had in my last car. Thanks.

Well I recently ripped apart the entire system and put in my own. Took out the factory JBL stuff and got my own toys in.

As far as I remember, I'm not sure if there access to tap into the rear speaker cables from the trunk. Another way (quite easy) is to get a wire diagram for your car's system.

Locate the rear speaker wires (colour coded, diagram explains in detail) from the harness going from the factory amplifier. Splice into that, and the run the wire under the kick panel and into the trunk where you can attach it to your line out converter and call it a day

unless if there is access to the wire (from the trunk) that goes to the rear speaker, i find my method quite easy. would take no longer than 10 - 15 minutes to run those wires

[wolfatwp]

you might get by using the wires you see at the bottom of the woofer in the trunk. but those are not the only wires feeding the speaker. that is just the low frequency, the high frequency go to the tweeter via seperate wires. the yellow wires are positive and the red are negative, i know, goes against common sense. feed a line output converter audio control lc2i, check it out. i just purchased a used 07 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!!!!!!!

jbl factory head unit 6 disc changer, nice piece!
audio control lc6i line output converter (magic little box made it all happen)
jl 500/1 amp on a jl 10w6v2 sub
precision power ppi 4240 4x30amp

and a million dollars worth of wiring and goodies

AWSOME SOUNDING SYSTEM

We just installed a sub in my camry and went directly from rear speakers and this was definitely easy. And works very well. But, I have the JBL with Navigation.

[wolfatwp]

I'm glad it worked out for you. the rear wires that you see in the trunk are low frequency wires to the rear woofers. this will work for sub only. the crossover point is probably 2500 hz to the woofers, maybe a bit higher. if you go full range, these wires will not provide frequencies above the woofer crossover point. so the amp you feed will not get a full 20-20k signal.
