Finally finished up my project. Special thanks to everyone that helped me out, and Jay1/WiSounds.
Figured I'd post some pics. It's a Peavey Low Rider 18" paired with a bridged Behringer EP2000. It's a 5.5 cube box tuned to around 32hz.. It's purely for music and parties.
I did all this on my porch and party room, definitely not a master wood worker or have done speaker work like this before. Yes I know things could/should have been done differently but turned out quite nice. Hits decent, though I think it overall needs some adjusting.. (will touch on that at the end)
4 cans of truck bedliner. Still have to put on the grill guard.
As I was mentioning earlier I think it needs some adjusting.. it hits hard, but not nearly as it should. Some songs it barely hits at all... (when my old sub would be going hard) It just sounds empty on a lot of bass heavy songs. I currently have the amp set up as follows.
Clip limiter on
Low cut filter 30hz (as opposed to 50hz)
Low cut filter on
Bridge mode on
The signal is coming from a home theater receiver "subwoofer out" through a thick subwoofer rca cable into a 1/4 mono TRS adapter, into the amp. The amp is hooked up to the driver using very thick copper stranded speaker wire.
Not sure where the issue is.. (maybe amp settings wrong / perhaps I need to use a speakon connector / maybe the box is at fault / maybe it's tuned all off)
