If you are set on replacing the oem subs/enslosure add back a couple smaller subs in that enclosure to play the higher frequencies that you don't want the subs to play.
Here is a similar build for reference.
If you can do that you are good to go.
You'll need quite a bit of stuff depending on your goals. I have an 8 speakers setup with two amps a dsp and MOST25 adapter with custom door panels and custom sub enclosure. I spent $13k with install.
If you're just trying to get more bass, you should follow what others have done in this thread...
Yes there is a way without issues. In my build I replaced every component. I believe this is the most pure/correct way of doing any audio build. But to replace it all with aftermarket costs a lot of money thanks to the fact we have a MOST25 system, which is a curse and blessing at the same time.
Ok...so.. to use the LC2i the factory amp needs to stay put. Have your installer tap into the post amp speaker wiring.
Also by removing the oem subs you are cutting out not only the sub bass but also the mid range bass. The front speakers do not play lower frequencies due to the 4" size. Your...

GESI cats is the future, companies like AMS have already started to transition over. They no longer sell a race cat and marked up the street cat by $500 since release, which says it's rated for 800hp. Maybe they will start creating some higher hp cats using some new material or better...
I got the 156lb version installed and find it to be stiffer than what I think it needs to be. Even at 152lbs it'll be too stiff. Do you think they can custom make some struts?
