Roll Off?

[Brightside]

Hello.
I have a 2015 Civic Si sedan. I'm loving it!!!! I already have installed a JL Audio 500/1 monoblock amp powering a 10w6v2 in a ported box and a cheap line out converter. I'm about to have a JL Audio xd200v2 2 channel amp and Polk audio mm6501's components put in the front and I'm going to keep my stock rear speakers powered by the factory amp for fill in. My question is, does anyone know if the 2015 civic si stock stereo has a bass roll off at higher volumes? I'm also having a LC2i Line out converter installed. I'm wondering if I need to mess with the Accubass or not.

Just a heads up, you do not need to use a loc. I'd read through this link below as it has a ton of helpful info in it. I don't know the answer on the bass roll off. I know it's not uncommon in factory setups though.

Great info, thanks. I've already purchased the LC2i. I like that it has separate volume controls for both the (Sub\amp) and (Front Components/amp). That way I can tune it to my liking. I'm gonna keep looking around to find out more about Honda Factory eq settings and possible bass roll off.
