[QUOTE="sundownz, post: 5938986, member: 549523"] Yesterday I put in another 45 degree piece: [IMG]http://www.sundownaudio.com/misc/96_Jeep/v2_dual15_box/Modifications_Begin_5-13-09/CIMG2230.JPG[/IMG] [IMG]http://www.sundownaudio.com/misc/96_Jeep/v2_dual15_box/Modifications_Begin_5-13-09/CIMG2231.JPG[/IMG] Nothing really changed - did 155.2 dB. Then I drilled holes to get the speaker wires out of the port... no change. BUT they were not sealed up - just holes. --- TODAY I got threaded brass rod, washers, and nuts to make a proper connection : [IMG]http://www.sundownaudio.com/misc/96_Jeep/v2_dual15_box/Modifications_Begin_5-13-09/CIMG2232.JPG[/IMG] [IMG]http://www.sundownaudio.com/misc/96_Jeep/v2_dual15_box/Modifications_Begin_5-13-09/CIMG2233.JPG[/IMG] [IMG]http://www.sundownaudio.com/misc/96_Jeep/v2_dual15_box/Modifications_Begin_5-13-09/CIMG2234.JPG[/IMG] [IMG]http://www.sundownaudio.com/misc/96_Jeep/v2_dual15_box/Modifications_Begin_5-13-09/CIMG2235.JPG[/IMG] I should add that before I had a smaller wire jumping from one coil to the other to parallel the coils. Now I have two sets of wires going to the common point (this is probably part of the gain I saw). [IMG]http://www.sundownaudio.com/misc/96_Jeep/v2_dual15_box/Modifications_Begin_5-13-09/CIMG2236.JPG[/IMG] So I am up 0.3 dB from my best score and 0.4 from the score I was doing yesterday consistently. I would say part is due to moving the wires out of the port (this has always gained me in the past) and part was due to the superior connection of running two sets of large wires off the coil.
