Robby Holmes Posted June 26, 2012 Report Share Posted June 26, 2012 (edited) problem in a nutshell: sub wont work. long problem: i have a simple doubledin touchscreen with RCA's --> 7band cadence EQ, then --> my amp. remote --> EQ + capacitor (zzz i know) --> amp. amp, and cap both turn on, have power etc. but the woofer wont play. whats the prolem' here?? edit: took a look at the VC, and the coil still looks to be fine.

sprkn_ranger Posted June 26, 2012 Report Share Posted June 26, 2012 Have you checked to make sure the coils are good on the sub? Take a dmm and see what the coils read. Also check to make sure all the wires are connected right.

sprkn_ranger Posted June 26, 2012 Report Share Posted June 26, 2012 Coil can look fine, but still be bad. Try taking a 9volt battery and touching it to the wires for the sub and see if the sub moves. It's called a "pop" test.

Skullz Posted June 26, 2012 Report Share Posted June 26, 2012 Have you turned on the sub output? Is the sub output turned up to max? Is the gain on the sub amp turned up enough to get sound? First thing to do is check and make sure all sub controls on the H/U are turned on and up. Next is the sub and check with a small amount of power from a 9v, 14v baterry or battery pack as a quick way of testing the sub. If those are working and you still have nothing then work down the line with rca's and eq as possible problems.

sprkn_ranger Posted June 26, 2012 Report Share Posted June 26, 2012 Ok now that we know the coil is fine, have you used the amp before on another speaker? If you have an iPod, you can use a headphone jack-RCA out adapter and hook those straight up to the amp an see if your amp is working right.

Robby Holmes Posted June 26, 2012 Author Report Share Posted June 26, 2012 figured it out. the inputs on one of my 3 pairs of RCA's to the back of my deck was improper -.- Quote '08 Chevy Cobalt coupe 2.2 base model trunk build: 2 9512iSC flatwound alum 1.5 coils -extra 9500 spider pack -8" platinum carbon dustcaps 1 DD Z1 (.375ohm nominally daily) 3g31 AGM 320a Ohio Gen alt 1 DD S4 4 channel 4 VO-M8v1's (holes cut for 3rd pair) 2 CS 6.5's 2 VO-B1's Sony XAV-601BT all Knu Krystal RCA's Cadence 7band EQ ______________________ 148.3db @ 32hz (burp) 148.4 @ 37 & 38hz (burp) 146.xdb 90sec average (center windshield) Link to comment Share on other sites More sharing options...
