Ok, new here and would love some advice. Have an 05 2500 Dodge quad ram cummins diesel. Just bought a Jensen MV9311 DVD headunit. Wanted something nice and with a DVD. Didnt really care about anything else. ok, since I just got my new DVD headunit, I figure I should replace the stock speakers with something better. So I ended up getting (4) new POLK AUDIO db690.
So I get it installed today and turn the music and find out not only does it sound the same, but it even sounds worse and plus now I get distortion . My buddies at Circuit city(where get all this audio stuff from) were suprised that there was NO difference and said that my headunit isnt making enough power and that is why there is NO difference. They also tell me to get a seperate 4 Channel amp to power the (4) speakers but I also am getting 2 or maybe 1 10" Type R which then it would require a seperate mono or 2 channel amp. Dont know what to do, either return these polks and just stick with my stock speakers and get the subs (not sure how thats going to sound) or get a 4 Channel amp to power those speakers. Im suprised tho, I cant believe that even with my pre-amp in the headunit, both the stock and POLKS sound the same.
My DVD headunit is actually NOT rated high, 160 Watts Peak Power (40 Watts x 4).
