LoudBimmer Posted September 8, 2011 Report Share Posted September 8, 2011 Today i finally installed my system in, and had high expectations, but was disappointed. Here's what i got: .5ft^3 sealed per sub with a common 2.5ft^3 ported chamber tuned to 49hz. ( designed by Ram-designs) sundown saz2500 2 sundown sa 10's kinetik 1800 knukonceptz 0 gauge wire and rca. kenwood HU I set gains with dmm to 45v (~2100 wrms), voltage does not drop below 13v, and around 14v while driving. I tried 49hz test tone and voltage dropped to 12.3-12.5v. I was expecting a huge voltage drop, but that it? I only moved gain and LPF, everything else i didn't touch. Compared to my previous set up with hifonics brz1200, it sounded way louder and better. Now, i doubled power but with crappy result. Is there something wrong with amp, gains or box?

jagblazer01 Posted September 8, 2011 Report Share Posted September 8, 2011 are you running a 4th order? It seems like its a box issue. Not to mention 49hz is really high for daily tuning Quote Team Sundown Audio / Team XS Power / Team SHOK SMD Super Buyer/Sellerwww.sundownaudio.com www.shokindustries.com www.4xspower.com www.excessiveamperage.com Link to comment Share on other sites More sharing options...

jagblazer01 Posted September 8, 2011 Report Share Posted September 8, 2011 looking at the design to me it seems like there is way to many areas for the air pressure to get stuck before it goes out of the port. its an interesting design though. just doesnt seem to efficient to me Quote Team Sundown Audio / Team XS Power / Team SHOK SMD Super Buyer/Sellerwww.sundownaudio.com www.shokindustries.com www.4xspower.com www.excessiveamperage.com Link to comment Share on other sites More sharing options...
