I have 2 used 12 inch Pioneers in a large ported box right now. These are totally temporary until I get money to replace the components. I just want to have bass in my car for the time being. I went to best buy and bought the Kicker PK DPK4 amp install kit. 4 AWG AMP 600 Watts rated. I only have a 300 watt amp right now, so it won't be too crazy. It will just add some much needed bass for my music.
I listen to a lot of like undergroup rap stuff (Spose, atmosphere, etc) along with other non rap stuff (Ska, alternative. etc). So a bit of everything. I assume that the amp install kit should be good for what I need. (darn thing was 100 bucks) My vision towards the end is to probably have a single ten or 12 in the trunk. Maybe 2 of each depending on what it sounds like. The different sizes sound like a pain now. And a larger wattage amp.
