134 db, I didn't spend but about $100, the entire system cost no more than 650. My first system I spent about 1000, and hit a 129, and that was with 2-8's being underpowered.
First system hit a 147 with two 12 fosgate xlcs and a fosgate200.2 next hit a 149 never really pushed em though with 2 jl w3s then new setup finally sqeezed 157 outta of crystal cmp 15 on a jl 500/1 amp and plan to gain alot more when i get a jl/1000 amp.
Oh ya and first system spent 560 on entire system next system spent 900 and then sold jls and spent another 300 on new sub i got so 1200 total - 200 for selling JLS so that equals 1000 not too bad for a 157
(this is mar 4) Thanks guys! The project is done and I found out that there is no correlation between these two. Get this, I got a 103% on it. Extra credit for most valid use of statistics! Thanks again!!!
