Bought an audiocontrol ls7i sound processor to retain oem head unit and steering controls. Head unit has enough tone adjustiment i was fine with it, plus i wanted stealth..everything appears boring and unassuming until you want it to get louder.
Power comes from a 500×1 rockford fosgate for the 10" rockford subwoofers. Then a rockford fosgate 300×4 amp for front rear speakers. Fronts i used Alpine 6 1/2" typr.r component speakers. Rear i used Alpine 6×9 coaxis in rear deck. I jnitially mounted tweeters from front component set in sail panels on doors but it was far to bright and over powering, so modified mounting plate for the 6 1/2" woofer mounted in door to fit tweeter and fired them up…very very nice sound now…just cost me $30 for new sail panel.covers from junkyard to replace the ones i put a 2" holes in to fit tweeters initially lol.
Ran a 9 wire from head unit thru car to trunk on passenger side to give signal to sound processor and 4ga wire down driver side to power all 3 components in trunk. Then a cheat to save running more speaker wire then necessary, while wiring the 9 wire to factory deck i tied front speaker wires from doors to the rear speaker wires…so intrunk all i had to do was run new wires from rear deck speakeds to amp and then lengthen the existing rear speaker wires to hook upto amp. Used to do that yrs ago and big time saver and works great.
Amps and processor mounted to top of sub box
Anyhow, just bought a complete sub box, bad to turn it upside down and made place.to mount components, built a rear "firewall" since i wanted subs firing into cabin and that requires sealing off trunk for noise cancellation purposes. Then added some alligator pattern material to break it up some so if a person folds seats down to see the subs its a lil different than just carpet.
Then since car is daily driver, grocery getter, sporting event taxi trunk needs to remain functional, but components needed protection from day to day living..plus wanted stealth. So went to junkyard and bought floor carpet.from another chrysler 200 so itd match, made a removable false wall and boom..open trunk and nobody thinks anything of it as everything is hidden/protected:)
Sounds great, sub amp has volume control so i mounted that knob in center console ao you can adjust it per music type. The 10" subs are probably the jack of all trades for accurate sound reproduction and enough to get loud if you want them too..ive found 12s and 15s to be a little more muddy sounding and good for ghetto bass vs a cleaner sound.
