TT-Es300

Thanks for responding, I finally gave up on trying to find a hole through the fire wall and drilled one last night. Yes, I do have my power cord running from the battery to my amp (with of course the fuse box next to the battery). But now I have run into a problem! Everything is hooked up as it should, I will explain how it is set up.. I have the amp remote wire intercepting the ACC (accessory) [red wire] connecting to the stock head unit. I found a similar schematic seen here: http://carstereohelp.net/wireharness_Lexus2.htm After that, I connected the RCA's running out of the amp to a RCA converter (which converts RCA cables to speaker wire) I then intercepted the speaker wire with the 8' Stock sub in the trunk. Now when I connect the power cord to the battery with everything else hooked up.. The POWER and PROTECT lights flash on my JL amp and then turn off right away.. I don't understand where I went wrong. Please help.

Hello, New to the forums, just got my first lexus off ebay. Auction can been seen here: http://cgi.ebay.com/ebaymotors/ws/eBayISAP...em=330241428269 Now installing a 1600w Class-D JL amp and two 12" JL W3's I debated on installing my Alpine CDA-9855 or keeping the stock stereo. I have decided that I will try the stock unit as it sounds great already. While I have already taken out the stereo I am having a hard time finding out how to run the power wire from the amp to the battery without drilling a hole through the firewall. I am not sure how I should run the wire and hoping someone here can help. I am also unsure how to remove the back seats as I don't own a manual for the vehicle yet. Any advice please let me know!
