Hey, just looking for opinions on components for my 08 limited. I have already gotten rid of the stock speakers and threw in two pairs of the kenwood kfc c6894ps for the front and rear doors. was wondering if i will hear a major difference with a decent pair of components. they are being powered by an alpine ktp-445u power pack which puts out 45w per channel rms. I still feel like its lacking a bit. also replaced the stock sub with the polk db840 dvc being powered by a rockford fosgate r250-1d. any thoughts on upgrading fronts, rears and the sub are appreciated. no boxes though, i need my storage area quite often. Thanks guys!
