What is the maximum input voltage the Amp can handle? My stock system is pushing between 6-10 volts that I'm trying to run into the amp. It immediately goes into protection mode when I hook up the input RCA. Others have hooked up this amp to the same system with no problems. Could I have a bad amp?

I don't, but I was going to stop by a few local installers and see if they would let me either try another amp, or test mine.

First, thank you all for helping me with this, it's truly appreciated! I thought it could be a bad harness too, but am not so sure now. The sub-thump harness connects to the INPUT of the stock Amp, so it's non-amplified input. 1. If there was a short in the harness it would affect the stock amplifier too. 2. I was able to plug the RCA's from the harness into some amplified computer speakers. They worked flawlessly, both channels. They just don't work with the Amp. 3. I've checked (and re-checked) the wiring on the harness against the car's wiring diagram. I'm pretty sure it's spot on. That is indeed the harness I have. Shouldn't be incompatible as several other camaro owners have used this amp with the same harness. Camaro 5 forums 2010 2SS Camaro. It's our dream car . Using the stock Boston Acoustic. It's fair as stock H/U's go, but lacks some bass. I'm eventually going to replace the stock Amp & Speakers.

I've now run 3 separate RCA cables, all of them cause immediate amp failure. I'm pretty sure it's not the harness as it works just fine on the powered computer speakers I tested them with. That suggestion got me excited as the only RCA cables I had tried were the expensive ones that came with wiring kits. I just tried some old cheap ones (wal-mart close outs) and the same thing happened. As soon as the RCA jack touches the Amp input the protection LED lights. ARGH! The amp works fine with everything EXCEPT the car RCA inputs. The car RCA inputs work fine with everything EXCEPT the amp. What the hell???

Brilliant idea! I just hooked up my camcorder with RCA out, and it worked like a charm. I even hooked up the sub box and was able to feel the Sub moving. I was just BARELY moving though, probably because the camcorder wasn't putting out much low end (I guess) So, it doesn't appear to be the AMP as I thought. All signs are now pointing at the Sub-Thump wiring harness. I'll check there now. Thanks for the help. Update: I hooked up some computer speakers to the RCA cables out from the Sub-Thump harness. They worked flawlessly, and they're amplified. So it's doesn't appear to be the sub-thump harness. I took the same RCA cables that were working on the computer speakers, and when I touched the first one to the Sundown Amp, it went into protection mode. I tried both RCA cables, and even the BR IN spot, every time the protection LED lit immediately. So, I guess it's a bad Amp. Crud, I guess it happens sometimes. Update #2: Ok, I just bought a RCA adapter for my Droid phone. I hooked the output of the Droid to the inputs on the Amp and BOOM! Got some thump out of my Sub. Tried the RCA from the Car, and instant protection mode. I am SO confused right now. So to summarize... Inputs into the Sundown amp: RCA from the Car (via Sub-thump harness) - FAILS RCA from my Camcorder - WORKS RCA from my phone - WORKS Output from the Car (via Sub-thump harness): RCA into Sundown amp -FAILS RCA into powered computer speakers -WORKS I am totally confused right now. I bought a voltage meter but am totally clueless on how to use it. When I set it to read Ohms I got: RCA's from Sub-thump Harness -anywhere from 18 - 30 while the music was playing. Is that normal? RCA's from my Phone -24.5 steady on one side, around 23.5 on the other. These remained pretty constant.

And why does everything else work with the Sundown Amp? I could really use some help, this is freaking me out.

Just installed my Sundown SAZ 1000D in my Camaro. As soon as I fired it up, the protection LED lit (I thought it was the power LED at first) I unhooked the output speaker wires and reset the amp (disconnected power & ground) and tried again. Still had protection LED. I then unplugged the INPUT signals, reset the amp, and this time got the power light (woohoo!). As soon as I attempted to plug in a INPUT line, the protection LED would light up. So it's the input causing the trouble, not the output. I'm using a wiring harness from Sub Thump, maybe it's bad. I checked the wires from the harness against the wiring diagram for the car and everything seemed ok. Maybe the RCA cables I used for the input are bad, I tried another set of RCA cables and the same thing happened. I even re-soldered the RCA connections on the Sub-Thump harness (just in case they were bad) and still get the protection LED. Could I have a bad AMP? Edit: I probably should mention that the Sub-Thump wiring harness plugs into the existing stock Amp. Essentially tapping into the existing inputs feeding the stock amp. I would think if it's a wiring problem this would have caused the stock amp to fail too. But it's working like a charm. Any advice?
