But after I get door panels, carpet, headliner, and a quieter muffler I plan on using 6.5" midranges in door panels, tweeters in dash corners, 6x9s in hat tray and a 12" sub in a box I built that matches the angles of the front of the trunk. 300 watt amp to the sub and a 75x4 watt amp powering the front and rear channels.
