'99 camry additional speakers help

[jakeoff]

I'm trying to put in additional speakers. The ones i have are in a box, so to replace the rear speakers i'd also have to dismantle the box speakers, so i'm just going to set them where the back passengers feet will be and hope that no one will complain. I'm 21, it's nothing i can't handle. Anyways.. a few questions

Will i risk blowing out my rear speakers if i attach an amp for my new speakers? fairly self explanatory as per fuses..

Can i attach two new speakers while keeping in my old front and rear speakers? If so, where can i attach wires and stuff. I've been looking everywhere for a schematic. If anyone could help me find one of those too i'd be grateful. I'm fairly in the dark here...

If i have to take out my rear speakers, and use the wires that connected them, how might i go about bringing the wires from the trunk to the backseats?

Thanks in advance

You can remove your rear seat cushion and run the speaker wires under the carpet and have it come up through a small hole. As long as the amplifier is rated at roughly the same wattage as your new speakers are, AND you have them set-up correctly, you won't risk blowing them out, not by a long shot. I don' have access to a schematic or anything but I'd say to splice said wires that will run under rear seat to where the existing rear speakers mount. Thats the easiest location.

If the installed stereo has its own amp, make sure the new amp is designed to tap off its ouput.
