toaster Posted March 5, 2010 Report Share Posted March 5, 2010 You have an alignment issue; nothing you can repair without proper tools. Also, the numbers change on your meter when you push the cone in due to it's inductance.

Rogers Posted March 6, 2010 Report Share Posted March 6, 2010 just swap rca cables... they arent that expensive... but a good test would be a ipod with a 3.5mm to RCA cable... hook it up directly to the amplifier... http://www.stevemeadedesigns.com/board/topic/79921-rogers-700-dream-car-update-page-17-a-wall/?p=2335774 93 Saturn SC2My system4 SA-15's Walled 2 Cerwin-Vega S2000's 3 Kinetik Hc2000's Dual 200amp alts. you guys done with the peepee touching contest or do I need to end it?

chewie Posted March 6, 2010 Report Share Posted March 6, 2010 did you accidentally cross over the two voice coil input wires.. aka reverse polarity on one and still hookin it up as normal. it will cause the coils to fight each other and just sit there and distort and sound like shit!! 91 dodge colt gt.. 4 custom t600 15s audioque 3500d.1 tuned to 25 hz... stay tuned. blazer stroker 15 brutus bxi2006d terrible voltage drop 145.4@38HZ...

toaster Posted March 6, 2010 Report Share Posted March 6, 2010 Your'e running two amps, one to each driver? Or, one amp in stereo to them? Did you not try switching rcas before hand, or drivers?

Rogers Posted March 6, 2010 Report Share Posted March 6, 2010 try pulling your head unit out of the dash a little ways and wiggling the rca jacks at low volume and see if it makes any noise difference... your symptoms could be either from bad outputs or bad rca's.... i would definately pull the rca's and inspect them for pinches, cuts or bare spots... http://www.stevemeadedesigns.com/board/topic/79921-rogers-700-dream-car-update-page-17-a-wall/?p=2335774 93 Saturn SC2My system4 SA-15's Walled 2 Cerwin-Vega S2000's 3 Kinetik Hc2000's Dual 200amp alts. you guys done with the peepee touching contest or do I need to end it?

Rogers Posted March 6, 2010 Report Share Posted March 6, 2010 i swapped rca's still the same problem, i dont have a ipod they're junk sry well i didnt necessarily mean an ipod... any mp3 player or portable cd player(if they still even exist) will suffice... what HU are you running? and how old is it? also... if your hu has more than 1 set of pre outs... you could hook it up to the rear out to see if that makes any difference http://www.stevemeadedesigns.com/board/topic/79921-rogers-700-dream-car-update-page-17-a-wall/?p=2335774 93 Saturn SC2My system4 SA-15's Walled 2 Cerwin-Vega S2000's 3 Kinetik Hc2000's Dual 200amp alts. you guys done with the peepee touching contest or do I need to end it?
