Im new to CarAudio and I would like to get everyones help choosing the best sub and amp for me. I have a 2010 Ford F-150 Ext. cab that i removed one of the back seats from and built a custom ported 3.1 cubic ft box to fill the space. im not sure if it matters but the port is a bottom slot port. Im looking for a 15 that will really SLAM!!! Im not looking to spend a crazy amount but i have a decent budget of $350 for the sub and another $250 for the amp, but anything cheaper would be nice. Im pretty much only into spl as far as this sub goes, i just want as much bass as possible. I would also like help choosing the best amp to go with whatever the speaker choice is. Thanks for the help!
