Thank you so much for your time. I went out to walmart and bought their cheapest sub possible, https://www.walmart.com/ip/Dual-Electronics-TBX10A-10-inch-Shallow-High-Performance-Powered-Enclosed-Subwoofer-with-Built-In-Amplifier-300-Watts-of-Peak-Power/54596677 replaced the soundstorm with it and the sub worked great. So this eliminates me incorrectly wiring the LC2i or messing up somewhere, as this proves it was the soundstorm subs problem. I purchased it off of amazon and luckily am able to return it. I have a civic and don't want to sacrifice any trunk space so that is why i am purchasing small ones to fit under the seat. I purchased this off of amazon today https://www.amazon.com/gp/product/B019Z3R582/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 hopefully it will be better than the one from walmart and if not, ill go ahead and sacrifice some trunk space to get the bass i want. Also, i specifically installed the LC2i to adjust for the bass roll-off in higher volume. Thank you again so much for your input!

I bought a 10" powered under seat subwoofer from the sound storm https://www.amazon.com/gp/product/B001CY13W2/ref=oh_aui_search_asin_title?ie=UTF8&psc=1 and used an LC2i to convert the speaker signal from the rear left speaker to RCA outputs. I do not have a subwoofer stock as i have the lower trim level which doesnt incude a factory sub. I finished the setup and can barely notice the subwoofer working. The sub turns on and does work, but is extremely weak/quiet, not even as powerful as the stock rear speakers. I have tried almost everything to try and get it to work and get more bass but nothing seems to work. If someone can give me some feedback or advice that would be awesome. Thanks!
