JBL Amplifier

What exactly are you trying to do?

 

This reads like Deja Vu. I am doing the EXACT same thing myself and the diagram I had was for an 08 Amp unit! Did you notice that your amp has 3 connectors, an 08 amp has only 2. I went to Toyota TIS and downloaded the info for a 09 Prius, and it has the 3 connector amp!!!

Here is the pin out!!

When I get hopme tonight I will upgrade this note, the connectors are labeled S-14 S-15, and S-29. I do not have the connector info on my computer here. If you want the PDF of the wiring schmatic, PM me and I will send it to you!!

Hope this helps!

 

Check your email. PDF sent!!!

 

here are a few weblinks that helped me through w/ understanding the jbl system:

If you have the JBL system, slide the passenger seat full forward and look see how many plugs the box under the seat has plugged into it. Thats the power amp assy for the Stereo If it is ONLY 2, the documents are relevant. If however, you, like myself and kurtjamesma have 3 connectors, its an '09 JBL package. I ran into this problem about a week ago when I started my Subwoofer project. I went to techinfo.com and downloaded the 2009 schematics, and lo and behold, we have 2009 JBL systems in our 2008 cars. Transition time came early fo some models I guess!..

If you want copies of the paperwork PM me and I wil drop them along!!

 

Ahh ok. You are trying something completely different than I thought. I never messed with the JBL system so I'm of no help to you. Sorry about that.

Could you post up the final results with a small write up when you are finished? It may help others in the future.

 

Hey Kurt, which speakers did you decide to tap off of. The Front L + R, or the rear L + R??? The reason I ask, I have been looking at the print and it looks like if you use the front set to drive the Sub Woofer in, it already has the high end cut out. There is a separate out for the front tweeters. The rear L + R feeds are full frequency and then use a capacitor at the tweeter to cut the low audio freqs!
I am planning to use the front feed myself since the amp already has a crossover built in and I won't even have to worry about a lot of "High End" getting to the subwoofer, where it is defiantly not needed!!!
What are you doing, Waddya Tink?

 

by mounting the lc8 & amp in the storage tray you won't have to worry about access to your tools & spare tire. if you look at my setup i have full access to all of those items. granted i can't completely remove my storage tray now, i can still lift it to get to the spare. my flashboard, which covers up all the process & amp wiring is also completely removable, so i can access tools.

if you are worried about access to spare tire, building a custom enclosure in place of storage tray could make it more difficult to get to the tire. that was my first option when i was designing the system. i dumped the idea when i realized the box design i would need & the work required.

 

Well all the work paid off. I went with a "BOSS 800" for the car. I did not want to really see it, just hear it. So I made Aluminum mounting blocks, and Grill Cloth covers for it, and here is the result,



This gives you access to all the controls, and wiring. The Amp itself is bolted down to the cove over the HV battery! It fits PERFECT in this location.



Put the covers back on the Sub, drop the mat back in and it is about as subtle as I can see!!!



It sounds pretty damn good!!! spent about 5 or 6 Pink Floyd songs setting it up...Holy cow my rear view mirror now vibrates and distorts the image!!!!!SWEET!!!

It fills in the bottom end that I thought was always missing!!!
