[QUOTE="valleyrider, post: 8464263, member: 668351"] So being new to this whole car audio thing I got my system somewhat setup and decided to see what kind of numbers my car would put out. I have a 2013 Hyundia Sonata 2.0t so it's a trunk build. I'm running an SQ2200.1 amp with an LC2i to provide signal from my stock navi HU. I have a single 1/0 awg run of knukoncepts wire with no other electrical upgrades done. I'm pushing a d2 12" sp4 subwoofer in a 2.75 cu box tuned to 31 hz. It gets pretty loud to my ears so I was curious to find out how loud it really is in comparison to numbers I see posted hear all the time. This being my first system I don't know what loud sounds like or what to expect so I figured I would find out. I ran a tonal sweep to find where my box and car peaked first. Found out 41hz is the magic tone my box likes to produce loudest. Best number I came away with today was a 137.5 db at 41 hz. First thing in going to do now is buy a battery for the trunk and see what the does. While I install the battery in going to look into doing the big 3 to try to get some better power to the amp as that seems to be what will help boost my numbers slightly. Just looking to keep my system sounding good not chasing numbers, was just curious how loud my perception of loud was. Any advice or experienced comments welcome. [/QUOTE]
