well ive noticed a little problem thats starting to bug me...ive had my system installed for like 2 weeks or so and ever since i got it, i knew my car was gonna lag, but its reaaaaaaaallllyyy laggn, like 0-60 takes a lot longer than it should and whats worse, gas mileage is sucking up the *** cuz of it....i have to push a lot higher rpms then normal and the car still doesnt go....and on top of that, even when im driving at low rpms and not acceling too fast, gas mileage is sucking....today i drove like a madman but i dont think even then i should be gettn the mileage im getting...my tank is more than 3/4 gone and im at ~225....i dont know if this post makes any sense but hopefully it does......wtf is wrong?

that's gotta be a monster system in there. try driving a full tank with no stereo and see what kinda mileage you get.

 

how big is that system?

 

its not even that big....2-12" kicker solo barics in a pretty big box ...dropped my rear about another inch so now my front is now noticeably higher than rear...

try taking the subs out and see if that helps. If not, then you may have other problems....
