I stumbled on your ID 15" Infinite baffle setup in your WRX. i've been scavenging the internet for something exactly like that (for a 2015+ WRX in particular) and was wondering if i can pick your brain my (first) IB setup.
My main two questions are that you mentioned you used 'L' brackets from the baffle to a flat piece of wood above and below the subs.... what did you mount the wood to and how?
I was also wondering how much power you were sending to your subwoofers consistently also. i've read you don't want to send the max rms in fear of bottoming them out and i'm trying to get a feel of some magical ratio of how much to turn the gain down. i plan to run a Dayton HF 15" for now and am looking to get an amp to match once i find that magical ratio lol. Any input would help a ton!!!
