I have a 15" Kicker CVR in a ported box tuned to 32Hz running off a kicker 400.1 at 2 ohms. Everything is fine when playing it loud, but last nite i opened the boot while it was playing loud and the amp started to cut out. When i closed the boot, it started playing properly again. Anybody have any ideas as to what is going on?
BTW, ive had the same system for at least 6 months and no problems. Its just when i opened the boot last nite it was cutting out. I closed the boot again and everything was back to normal. It never happened when i had the sealed box, maybe something to do with the port?
That's really strange man. It could be that your sub in the ported box trips out when it loses cabin pressure but I have never heard of that making an amp cut out. If the sub is facing rear why not take a look at the cone just as you open the boot and see if it does anything weird before the amp cuts out.
I was thinking that it dusnt like open spaces... But ive never heard of that either. It doesnt do anything weird before it cuts out, just stops and then starts again, then repeats until i close the boot. It works fine when the volume is down though, but it dusnt help if i wana make a video
You said that your boot light can be switched manually, but there should also be some kind of switch (you know the kind that pops out when the boot is open and turns on the light, just like on your front doors). Hold that switch down and put some duct tape on it to keep it from popping up and see if that solves the amp problem.
Well I don't know what to tell you without actually being there. Maybe some wires shifted and are getting crushed or something like that. You will just have to go columbo on the b!tch and figure it out
Yea im totally lost with this one. I can usually fix problems with car audio, but this problem is one-of-a-kind. lol Il jst have to play around with it and see what i can do. Btw thanx alot for trying to help. Much appreciated.
I happens more than ppl think, especially when their box moves all around. All they know is the amp/sub went, all of a sudden, but not why.
Why you? I dunno we're well above my head. This is just something i observed watching draw results when moving my enclosure closer to further from the gate of my old rodeo.
Do about it? Assuming im correct, a new/different enclosure.
Easy to test renegades theory by just plugging the port(s) thoroughly.
But I seriously doubt that the impedance could sway enough due to loading to make a Kicker amp shut off. Unless your particular amp is developing problems or possibly overheating where it is mounted.
Hmmm, looks like ive got some playing around to do. Ok il try to plug the port and see what happens when i open the boot. If that works, well then thats the problem and i guess il jst have to live with it. (until i can be bothered to build another box). And to Brads thoughts about the amp going bad, i continued to play the music loud after it was shutting off with the boot closed and no problems. So i dont think that its going bad. (hopefully)
Well what I meant is that if the amp is getting really hot where it is mounted, or is developing some issues, then a relatively small impedance swing (like renegade is describing) could well make the amp go into protect because it is borderline as it is...
Ahh i see what your saying. I hope the amps not going bad, i cant afford another one right now. (Btw the 400.1 kickers are worth $400 here in australia )
Maybe the 15 watt bulb is the culprit. It puts a strain on the electrical system, causing amp to protect due to low voltage.
^^^j/k ^^^^^
Try putting a volt meter on the power wire when it doing it. Whats the voltage read? Is it steady? If so its a fluke box/sub/amp/boot combo cone amuck.
Its 35 now. Celcius that is so thats 95 farenheit. Yes yes im melting right now in front of the computer . It has been worse tho. The highest i can remember was 45 celcuis (113 farenheit)
Which is why you need to check your amp temp by touching it after it shuts down, and possibly move it to an area that gets more airflow. That amp doesn't have a fan, I used to own one and it is a rugged little amp but it doesn't like to overheat.
Except I think it has nothing to do with the light. I think you're simply loosening a connection, or possibly grounding something out every time you open the trunk.
"its either low voltage, caused by impedance shift when the environment changes (opens the boot) or the suspension has an issue causing the coil to rub when loaded that way (loose spider somewhere)..... or maybe he only has the car off with the hatch open, causing low voltage"
