just about how much to fix these 2 problems? I have both of these problems also.

thanks for the reply, im not going to use the stock amp to hook it to the new sub, only looking for the remote wire to the new amp in the trunk, does this stock amp have a remote wire?

Hi, I am planning to install an amp with subs, wondering if theres a remote wire and rca outputs from the stereo or not. If not I'll prolly need to cut the rear speaker wires and link it to the amp? and for the remote wire, I probably need to find the antenna 12v wire to connect to my remote wire on the amp? also, is there an stock amp in the lexus already? I've been reading a few post and they said its under the chair? If so how can I get access to it and does it have a remote wire where i can link it to my new amp? Also, is there an online manual for this car? I've tried looking for it in kragen, autopart stores and couldn't find any. If anybody have experience with this, any help will be greatly appreciated, thank you.
