Hi
My Toy '92 Surf SSR-X came with an aftermarket CD Player wired to the front speakers only which the previous owner blew up.... : (
So no tunes and hence begins my journey.....
Had a look at the wiring after I pulled off the dash/glove and the previous owner must have read how to do it on the back of a CornFlakes box.
I managed to wire up new front speakers fine. I took apart the rear panels and found the rear speakers still in place. These are powered (amp'd) speakers.
Browsed the web and found some interesting stuff like you need to
connect the External Switch Amp Power line from the CD/Tape Player unit to the
rear speakers. DO NOT mistakenly connect the ANT. Power line to the amps as the amp'd rear speakers will work ONLY when the AM/FM radio is on, not CD or cassette.
Here's where i need help:
1. How do I safely
test that the amp'd rear speakers work?
2. The rear speaker unitss have 5 wires. Presuming they are the Amplified Rear Speaker type, I have no wiring schematics and need some help on hooking up my sound to these amp'd rear speakers
Any help would be greatly appreciated.
Thanks in Advance
Pete
p.s. here is a good site for sound wiring for most vehicles www.installdr.com

It's really difficult to help with this sort of problem over the
forum, even with more info (cable colours/sizes) Without checking with a
test light or multimeter a certain amount of assumption would be involved...Maybe someone on here can help with a wiring diagram?? I know the full workshop manual is on the net somewhere for download (for 3lt 96 model anyway, not sure for yours. Can find out for you or try a search yourself). Remember the inputs for your amp'd speakers are going to be low level inputs... don't just hook up the speaker wires from your head unit, you'll just fry the amps ... either use the low level outputs (RCA plugs on back of head unit) or bypass the amps on the speakers. If you have a fairly decent head unit it's inbuilt amp will most likely be just as good or better than the amps on the speakers.
Another option is to replace the rears all together. If on a buget try Jaycar electronics, their 'Response' brand of speakers have excellent specs and are great value for money, the 6x9's are especially good.

Thx
I would really like to know the site for the full workshop manual - I did a search but came up empty !!!
I would really like to know how it was wired up initially (curious)
I will try the RCA outputs wired to the rears first as they look real neat in the box behind the panels- i dont want to hack the interior too much as I want the interior to look like stock as much as possible.
If that doesnt work out I will have to pop into Jaycar next payday

Successfully hooked up the speakers and have drawn up the wiring diagram for anyone who wants it email me on petersinclair@fastmail.com.au
Found two things that were wrong:
1. My ANT. POWER and CONT. POWER outputs on the unit do not work hene no power to the amp'd speakers in the rear.
2. Original cabling to rear speakers have been cut somewhere!
I re-wired the speakers along with IGNT.POWER and GND to the rear.
With the Toyota Amp'd Speakers, there are 5 inputs and they are (as Bradley pointed out) +VE, GND, SPK+, SPK-, CONT.POWER.
Since my stereo is #*&*%^%$, I wired the IGNT.POWER to the Speakers CONT.POWER input which means that they will switch on even if the stereo is off.
This is not ideal but i Have sound
THx for all the support and I have hunted down some Toyta EPC Discs if anyone is interested.
