Scapelli21 Posted July 29, 2010 Report Share Posted July 29, 2010 (edited) Just installed my 18" Nightshade again...it has been sitting at a friends house for months now, no power. I hook it up to an AQ3500d.1 and stuck it in the box I used it before in which IIRC is 4.1ish tuned to 30hz. Everything on the amp hooked up right....no sound just a slight vibration. Turn the gain up and nothing. Then I remember Jacob telling me sometimes coils are mislabeled backwards. So go to take it out...the sub stinks pretty damn bad but not like a coil or really anything I personally have smelled before. Coil look fine, reads fine. Spiders look fine. Cone still stiff. Hook the coils up correct this time and anymore than 1/4 gain and the sub bottoms out and isn't even that loud. This sub was built to take a 3000d...it hasn't been clamped but a guess is that it's seeing no more than 1500w and I think thats being nice. Now, before when I had it on my 3000D, it bottomed out at times but not this bad. Any ideas on how to fix this or is just in need of a recone?

Rogers Posted July 29, 2010 Report Share Posted July 29, 2010 check your coils with a dmm first... then start troubleshooting with the amp Quote 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?

Scapelli21 Posted July 29, 2010 Author Report Share Posted July 29, 2010 Already checked the coils as stated, they read fine...2.4 and 2.5 respectively, it's a d2 sub. So basically, the consensus is that I should start looking into the amp instead of focusing on the sub. What ideas there then?

chapo123 Posted July 29, 2010 Report Share Posted July 29, 2010 could be the box. free air it and see what happens Quote Steve I don't know why but everytime I see your new paint I want a Dr. Pepper...... is this normal? heres an analogy for you. running a high power stereo without a fuse is like having unprotected sex with that hot chick at the bar with the sketchy sexual history. Sure you may be fine and nothing happens but that one time something does happen you're fucked. i dont want woofer broke like bass sound clip clip and voice coil overheat 2 sa12s, saz1500 build log http://www.stevemeadedesigns.com/board/topic/91183-chapo123s-sundown-build-log/page__gopid__1250604entry1250604 Link to comment Share on other sites More sharing options...
Rogers Posted July 29, 2010 Report Share Posted July 29, 2010 actually it may just be too much power... how much port area do you have? and where are your settings on the Hu set at? it doesnt matter if the gain is only up a tad... if the settings on the hu are cranked up you could still be over driving the amplifier Quote 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?

Scapelli21 Posted July 29, 2010 Author Report Share Posted July 29, 2010 It's not the HU settings...everything is set at 0 or lower. 6" aero which is enough for the size box. No clipping at all. The sub still smells free-air.

chapo123 Posted July 29, 2010 Report Share Posted July 29, 2010 how close is the sub to the aero port..?

Red-navi-916 Posted July 29, 2010 Report Share Posted July 29, 2010 From what I read sounds like the problem I had, I put two 18s into 8 cubes totall and all I got was cone movement no sound at all. Come to find out, I didn't have enough air space.. I would try a bigger box Quote BUILDLOG http://www.stevemeadedesigns.com/board/ind...showtopic=61862 "98crewcab"Never a POS....just always "a work in progress" lol that's how we roll bitches!!!

Scapelli21 Posted July 29, 2010 Author Report Share Posted July 29, 2010 I have been thinking about that but that doesn't explain the smelling that started when the coils weren't wired right and the sub not moving. Here is a link to the build.http://www.caraudioclassifieds.org/forum/showthread.php?t=9967&highlight=scapelli21 Quote 2003 Chevy Trailblazer LTZ Pioneer 980BT 16 SA-10's - 4th Order Bandpass NS-1 - 3 D3100's DC & XS Power, Audio Technix, Sound Deadener Showdown Team Sundown Audio Link to comment Share on other sites More sharing options...
chapo123 Posted July 29, 2010 Report Share Posted July 29, 2010 and also check your subsonic and lpf Quote Steve I don't know why but everytime I see your new paint I want a Dr. Pepper...... is this normal? heres an analogy for you. running a high power stereo without a fuse is like having unprotected sex with that hot chick at the bar with the sketchy sexual history.
