n8ball2013 Posted June 27, 2012 Report Share Posted June 27, 2012 Sure can check each coil with a multi meter. Visually inspect wiring and the woofer for damage or bare wire touching metal THERE IS NO BUILD LOG! 1998 Chevy Silverado ext cab Alpine CDA-9887 4 Team Fi 15s 2 Ampere Audio TFE 8.0 2 Ampere Audio 150.4 3 Digital Designs CS6.5 component sets Dual Mechman 370XP Elite alternators inbound! 8 XS Power d3400 6 XS power d680 Second Skin Stinger Tsunami Wiring Sky High A Real Voltmeter not a piece of shit stinger.

Skullz Posted June 27, 2012 Report Share Posted June 27, 2012 What H/U do you have? When it stutters or shuts down what exactly happens? Does only the sub amp shut down or off during this time or everything? 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...
oeking87 Posted June 27, 2012 Author Report Share Posted June 27, 2012 Like your setup n8ball2013! but i'll have to check that out i want to use the ohm setting on the multimetter correct? Link to comment Share on other sites More sharing options...

Does only the sub amp shut down or off during this time or everything? Nothing turns off technicly. Everything is still lit up its just the subwoofer will stop make sound for a secound then go back to normal if i don't turn the volume down it usualy keep doing it but sometimes if will only happen once and then be fine without turning it down its strange. And i have an alpine cda-123 Link to comment Share on other sites More sharing options...
Skullz Posted June 27, 2012 Report Share Posted June 27, 2012 When you did the big 3 did you remove stock wiring to the alt or leave it on and add to it? I know with alpine that if the H/U voltage drops to 11v it will stop for a split second till voltage increases, you would need to double check the H/U voltage with a meter but it is one of many possibilities that may or may not be it. Another thing is the amp shutting down from to low an impedance and that alpine is 2 ohm stable so if you have it at anything below 2 ohms it might be shutting down from it. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...

I Kept the stock wires with the big 3 too hard to trace them so i just added 1/0 with it, and the amplifier is at 2ohm Link to comment Share on other sites More sharing options...
oeking87 Posted June 29, 2012 Author Report Share Posted June 29, 2012 Random times? Not just full tilt? Try this: run a wire from the + on your amp to the remote turn on on your amp so it's always on. If it works fine, your remote wire is wonky or you might need a turn on relay That didn't help.

oeking87 Posted June 29, 2012 Author Report Share Posted June 29, 2012 And i did another test today i kept my volume that never cuts out and turn my bass all the way up and it cut off this is so f*&%ing stupid my damn gain is at zero i would rather fry a subwoofer than deal with this s*%@ at least then it would be a easy fix to alpine headunits in a row have done this and ive never had it happen with my old alpine headunit and my two directed 1100d's maybe i should just buy a distrubtion block and hook them back up because this is getting f(&^ing rediculous!

BeAlLsTaR13 Posted June 29, 2012 Report Share Posted June 29, 2012 have you checked your fuse under the hood? youd be surprised, i was at work and a similar issue came in, i wasnt seeing a full 12v at the amp like i normally would, i looked at the fuse and it was not blown/black, took my dmm and saw a huge voltage drop on the amp side of the wire, swapped the fuse for the hell of it and sure enough the problem was gone customer had the same problems as what you are describing with subs cutting out at random times Team Sundown Audio**CURRENT** -- 2012 Scion tC Build Click Here **OLD** -- 2002 Pontiac Grand AM Build Click Herecheck them out, slap me a comment2002 Pontiac Grand AM SE 2.2l 4 cylinder ecotec.-------------------------------------------------------------------Head Unit - Alpine CDA-9887Subs - 2x Z 12 v.2s - v.3 + NS Soft partsAmplifier - Sundown Audio SAZ-3500DEnclosure - 3.33 Cubes tuned to 34.66hzFront Stage - JBL P660c 6.5" ComponentsRear Deck - Powerbass 4xl 6.5" Mid-RangeFront Stage Amplifier - Sundown Audio SAX-100.4DWires - Kicker Hyperflex 1/0, KnuKonceptz 1/0, Knu 4 and 8 Gauge, Kicker RCAsElectrical - 275 AMP DC Power H/O Alternator, XS Power S3400, XS Power D2700Videos - http://www.youtube.com/user/BeAILsTaR13------------------------------------------------------------------- Link to comment Share on other sites More sharing options...
