fecupe2001 Posted February 21, 2013 Report Share Posted February 21, 2013 Ive also found amps that are strapped are more "sensitive" and protect easier Ding ding ding, we have a winner!!! I almost never use strapped amps at 1 ohm , the slave amplifier protect very frequently, i would run them seperate at .5 ohms a piece and gains matched, should stop the problem But then again, lunchbox knows way more about this than myself, so now i´m doubting my point lol I´m the SPL Gains topic creator!! wanna get louder?? check this: SPL Gains.

AmmoJammo Posted February 21, 2013 Author Report Share Posted February 21, 2013 I really can't risk running them not strapped, because if one amp goes in to protect, chances are I'll have four dead woofers As has been mentioned, its always the slave, not just with the DD amps, but with others I've tried too. I've had amps where the slave wouldn't even power up?! But what part of the protection circuit is the issue... Link to comment Share on other sites More sharing options...
fox_racin4 Posted February 21, 2013 Report Share Posted February 21, 2013 So what you want to know, is how to bypass the protection? 1998 gmc extd cab 12 crossfire C710s 4 SAZ-4500s 3 Singer 400A altsbuncha mids/highs Team Asshole Link to comment Share on other sites More sharing options...
AmmoJammo Posted February 21, 2013 Author Report Share Posted February 21, 2013 not at this point in time, rather I'm wondering which part of the protection it is that causes the issue. Link to comment Share on other sites More sharing options...
AmmoJammo Posted March 2, 2013 Author Report Share Posted March 2, 2013 I wonder if I could gain match the two amps, and run one voice coil from each sub, all four in parallel (0.5ohm) and the same for the other voice coil from each sub. It would mean that if one amp shut down, all four subs would still be on, but at a reduced volume, however, I'm not sure how the back emf might screw things up...

AMI CUSTOMS Posted March 2, 2013 Report Share Posted March 2, 2013 Un strap them Or more power supply Those are your options OR get the protection circuit modded.

cc_audio Posted March 2, 2013 Report Share Posted March 2, 2013 The very fact that you're running two Z1s in and out of protect over and over blows my mind. They pop faster than popcorn even when well cared for, trust me I've had one. So lets just state the obvious right off the bat, you are a VERY lucky guy that they aren't blown yet. And my next word of advice is sell them. You are running Z1s strapped with clipping at .5 ohm with a stock alt on severely in-adequate electrical. You are probably chasing a multitude of problems that you will probably never be able to fix without fireworks leaping from those amps. Adding a batt causes protection is just silly, there's more likely another underlying problem. My advice? SELL THE FUCKERS! Yeah, they make some big power but they are the furthest thing from reliable you can get. So get a reliable amp that is known to take abuse. Get yourself a 12k, like DC 12K, AB1100.1 or Cactus K12 (the list is bigger than that). Something that you don't have to strap, will like your stupid low impedances and you know will be able to handle your poor electrical (at least for a while anyway). And don't tell me you can't afford it, how much does it cost to have those Z1s repaired? Oh wait, let me dig through years of emails to check myself. Getting DD amps repaired is insane. Do what you want, there's probably nothing to gain from fixing your protect issue. Seriously. It's all gone! The Celica Build Feedback If I buy something from you, DO NOT USE FEDEX!

Not sure if you even read the thread... more batteries = more protect... I can't run one amp per two subs, as if one amp goes in to protect, I'd probably kill all four subs...

Do what you want, there's probably nothing to gain from fixing your protect issue. Seriously. I've actually never understood how people so often killed their Z1's, they must be doing something very wrong, as I've found them quite reliable, even when abused. Cost to repair them, well, I bought one of these amps already blown, total cost to repair it was about $20 in parts. http://www.stevemeadedesigns.com/board/topic/135563-the-wagon-two-12s-few-thousand-watts/?p=2190881 Sure, if you're not capable of doing it yourself, I can understand why you wouldn't want to run them below rated impedance.

CortezDTV Posted March 3, 2013 Report Share Posted March 3, 2013 Ur clipping the fuck outta thoes amps..... With voltage drop comes clipping Clearly u don't care about ur gear But let's just look at this quote "Amps both fixed and wired up... clamped 8000watts from the pair... got a nice burning smell, and smoke wafting from the port... *sigh* not quite as loud as I was hoping for, but it's an improvement " Can we see clamped numbers and voltage!!!???? And even better "lets just say, it won't do music flat out for more than about 30 seconds. D34 Exide Orbital up front (basically the same as an Optima yellow top) and the D31 XS Power in the rear stock 120amp alternator?" Ha. Ha. Ha Are u still gonna argue u have enough voltage. Get real! Everyone has tried to help you, it's YOUR decision to take the good advice given a ton of people before on this thread or dont. but please don't act like you have the electrical to support that and then wonder why your amps protect SCSB Santa Cruz Speaker Box Build logs: Daily Driver Lemon Marquis 2 american bass 750.1s 350.4 on 14 focal 6.5s sq 945 on 4 hertz tweeters Mystery subs http://www.stevemead...__fromsearch__1 The Mustang 'dubbed' Shirley the project from bullet holes to badass http://www.stevemead...cond-skin-time/ Link to comment Share on other sites More sharing options...
