3 years ago I began this journey for car audio perfection and I still have yet to be satisfied. Thanks in advance for reading this and spending your time to help me out. Here's some info to start off on, I have a 2004 Pontiac Grad Prix and it has a pretty big trunk for a sedan. I installed a Kenwood KDC-348U head unit, Alpine PDX-F4 (4x100w) amp, Polk MM6501 components in the front and Kicker KS693 3 ways in the rear deck.
Here are some issues I am facing: In the grand prix, the speakers mount into a plastic housing that CLIPS into the body of the car. The front sounds great and I love the polks, they just lack a little on mid bass but I plan on fixing that with sound deadener and making a new mounting bracket. The back is my main problem. Since I installed the 6x9's, they buzzed whenever the bass hit but provided a relatively full sound. However I still have yet to experience the seat rumbling sound that I feel a $600 system should put out. I attribute the buzzing to the plastic housing the speakers mount in and the panel resonance of the rear deck.
Now, the kickers in the back have died. So my options are: put another pair of 6x9's in the rear with new housings and sound deaden the rear deck OR bridge two channels of the amp and run a 10" sub (200 watts in a sealed box). I listen to rock, alternative, indie, metal, electronic, some hip hop, everything under sun really. I'm looking for a full sound spectrum, from feeling the bass in my feet to the great highs that I know the polks put out up front. I'm going for sound quality but i wanna be able to feel and hear the 400 watts this amp is putting out. If i go with the sub i can always add the 6x9's down the line and use the head unit power for rear fill, but will the 10" give me enough low end that im looking for. Let me know what you guys think, any input is greatly appreciated!
Thanks again,
Zac
