Hey guys I need your recommendations and advice on a new speaker upgrade I want to do in my 03 tacoma extended cab.I am planning on installing 6.5 component speakers. My budget is $550 for both front and rear speakers. I do plan on adding a sub later on, my headunit choice will most likely be a pioneer single din. What I want is good quality with clean accurate sound and with good mid bass. I do plan on running a 4 channel amp as well, so if you guys have any recommendations for that too please let me know. Thanks!
