BeAlLsTaR13 Posted September 7, 2010 Author Report Share Posted September 7, 2010 Swapped my RCA cables today, thought it was fine after I tested was going about 20mins, got everything assembled the poof, protect once I started again 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...
BeAlLsTaR13 Posted September 7, 2010 Author Report Share Posted September 7, 2010 Ok so here's more results I did 5 5 sec 45hz burps IN box, protect twice. Then 5 5 sec 45hz burps FREE AIR, no protect Then 5 5 sec 45hz burps IN box, no protect Now, halfway between each burp I noticed something.. I heard an audible change in loudness, it changed a lot, quieter. Turned down and restarted, started loud and did the same 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...
audiofanaticz Posted September 8, 2010 Report Share Posted September 8, 2010 A strut tower is a bad place to ground too imo! Im betting you have a bad coil, or a coil on its way out. I would pull each sub out of the box, and check each coil separately by itself to make sure all coils are good. When trouble shooting things like this, checking the impedance at the outside of the box is just not enough. You could also put your dmm on the beep setting so it makes a sound when the probes are touched. It should also do the same when you hook your dmm to the coil. then push your sub cone in and out, if you hear a break in the beap you may have a lose connection on the tinsel or the former, or under the dustcap. I know some amps can be very protect happy when something is blown. My dd 4channels are the same way, they work fine and low to mid volumes but will go into protect when i crank it up if I have a blown tweeter but again completely fine at mid volumes with the blown tweeter. They are so protect happy that if I disconnect the fried tweet from the crossover the amps will still sense the impedance being not correct and protect at high volumes. just a few things I would try.. good luck Link to comment Share on other sites More sharing options...

Toady Posted September 8, 2010 Report Share Posted September 8, 2010 maybe the coil has a faulty tinsel or something. normally a blow coil would not read an impedance or it would jump around like crazy, lol thats what happened to my alpine. (Strut Tower) <-- I thought that was a good grounding spot?? Link to comment Share on other sites More sharing options...
BeAlLsTaR13 Posted September 8, 2010 Author Report Share Posted September 8, 2010 Yeah I thought strut tower was good as well, but I was talking to rusty he said the slightest thing could change the resitance 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...
Toady Posted September 9, 2010 Report Share Posted September 9, 2010 F*** it im still using strut tower, there has always been a discussion between whether the strut tower, direct battery to battery, or wheel well is the best. Link to comment Share on other sites More sharing options...
BeAlLsTaR13 Posted September 9, 2010 Author Report Share Posted September 9, 2010 We found the issue...

BeAlLsTaR13 Posted September 14, 2010 Author Report Share Posted September 14, 2010 Well this is what's up, I have no absolute chance at winning finals running at 2 ohm on this amp, only did a 41.8, my cvx setup was louder by almost a db, I can't run at my .7/.8 due to my no rise issue (if this really is the case), if I were to wire in parallel for my .7/.8 final impedance what are the ways I can increase my rise or impedance?
