well. i am yanking my hair out trying to put together a monster of a stereo in my ext. cab taco. i ripped out the stock tape/cd player (2 din) and put in a kenwood eXcelon 915 and a pocket to fill the extra din. i then installed 2 sets of pioneer premier ts-c603 6.5" components speakers (front and back). they are the best 6.5" pioneers on the market. now to the problem... SUBS!!! there is no practical way to put a good sub box in the ext. cab. unless you wanted to not be able to have any use at all for the extended cab. i have thought about truck boxes but i don't know about that either. any suggestions? also, where is a good place to mount amps?
