Post Number: 5355 Registered: Nov-05	Posted on Monday, August 04, 2008 - 14:23 GMT I used to run SX 15"s at 28hz.. never complained about the lows.. they got down I'd retune.. keep in mind your only running 1 12" so you can only expect so much What kind of power are you running? box specs? port placement? how many square inches of port?

Post Number: 6598 Registered: Mar-04	Posted on Monday, August 04, 2008 - 15:28 GMT I'm w/ Kevin, I also ran an SX15 a few years ago. Had it in an ext silverado in 5cuft tuned to 29hz. On a JBL BP1200.1, that setup did 142's at 32hz. SX's can get low and loud...mean daily subs. Try that SX12 in 2.5cuft tuned to 30hz or so. Try the 15" in 4.5 at 30hz.

Post Number: 5357 Registered: Nov-05	Posted on Monday, August 04, 2008 - 16:49 GMT not enough port area for that size box.. rebuild with 2cubes after displacement .. 32 square inches of port tuned to 30hz and youll be happy .. hopefully if not add a second btw, why not just run the 15" in there? bucket seats and a center console with it downfiring FTW

Post Number: 5358 Registered: Nov-05	Posted on Tuesday, August 05, 2008 - 03:06 GMT i ran the two SXs on two 35.1s .. stock electrical and just two yellowtops the jetta had a 90amp alt as well two SEs will pound if you got enough volume to run two ported, great subs
