well, as most of you know, i have an xx-goliath that i have been waiting for some time now to get back from CIA engineering. first, a little background, i bought the amp off of forum member BigOso, and after 2 days of use, it crapped out. well, i sent it off to CIA, and within three weeks of me shipping it out, they had repaired it and sent it back. so problem fixed right? haha, wrong. well, after only an hour of use this time, it goes right back into protection mode, same exact symptoms as last time, and ever since then, i have been in hell trying to get info from them about it, and get it back. well these are the details of them lying to me about deadlines, making up excuses why it isnt done, and a story of me and my amp, plenty of reason to suggest others to never use them.

Joe,
this is brandon with the xx-goliath that was repaired and sent back to me last week. i had an aopportunity to install the amp today and test it out, and it worked perfectly at one ohm for about an hour i would say, then i hear a very loud popping noise, almost like a firecracker, then it went back into protect again. this amp is really starting to frustrate me man. when i unhooked everything and took the amp out of my car, i can hear something rolling around loose inside of it. i know that you all have a 90 warranty on the amps once u repair them, i was wondering how i need to go about taking care of this. thanks in advance.

Brandon, the only thing we did was to re-install seven broken output fets and the sil-pad insulators that were missing.
If you heard popping and cracking, something blew in either the power supply or the output. Your amp was tested three times and burned in under a 2 ohm load for 1.5 hrs.
We'll have to check it out and see whats up with it at 1 ohm.
Our warranty only covers parts and labor on what we repaired.
Send it in and we'll get to the bottom of the problem.
email me your set up also so I can try to figure out what might have caused the amp to blow mosfets and go into protect.'thanks,

i was running it on two kicker fifteens, dual 4 ohm coils wired in parallel to a one ohm load.

I've got to assume that maybe there were more mosfets that were cracked at the solder joint that just weren't ready to break. Thats why I usually replace all at one time.
I guess I was just trying to save you a couple bucks. Sorry for that. When I get the amp, I'll open it up, take pics for you and we'll go from there, Cool?

ok. the amp is now on its way back to you. i sent it out via fedex today, so i assume u will recieve it tuesday or wednesday of next week. after i had dropped it off, i realized i had completely forgotten to tape my contact info to the top. and to your earlier email, yes, after it initially went into protect, i turned my vehicle off, when i turned it back on, there was one loud popping noise, almost like a firecracker, i didnt hear any cracklng or sizzling. i hope this helps you find the cause this time. thanks again for you work and patience.

Hi Brandon,
Finally got a chance to dive into the amp.
Turns out, just as we suspected. Apparently there were a few more mosfets that were cracked at the base and when I put the clips back on, that was all it took and they, too, broken at the solder joint.
When you fired it up, the broken connection arced and blew. Thats the pop sound you heard.
With your permission, I think our best bet is to go through each mosfet, power and output, and if any remotely feel cracked, take them out and replace with new. I'll go ahead and hand solder each mosfet joint to insure a proper connection.
Let me know if this is the way you want to go. I don't feel comfortable just replaceing the broken and blown ones. I feel we'll just run into the same situation again. So, basically, we're wanting to do a rebuild.
Thanks,
Joe K
