I have a 1999 ford ranger xlt 4 dr v6 3.0 flex fuel edition. I have a kenwood hd545u headunit, pioneer 6x9 speakers in all doors, a jvc 12in 800 watt 4 ohm sub replacing the back seats and its powered by an 1100 watt crunch amp. I also have added a million color neon lighting kit(interior and exterior) from ledglow.com, it has a glasspack muffler that is directed down about midway on my truck, and it has smoked taillights and fully tinted windows. I am open to any advice from halo headlights to performance cold air intake. Please let me know what add-ons would really benefit my truck. PS: I like dramatic and obvious results so things that don't cost very much and make an enormous difference would be amazing. Thank you for all advice.
