Audiopipe APSM-1500 Protection for a few seconds?

[Quick 10+ year member]

I have the audiopipe apsm-1500 hooked up on a audioque HDC3 12" and that **** booms!!! It's great. I just put it in yesterday but so far I have noticed 2 things with it, when I turn my volume up over 21 (I should be able to put it up way more) on a hard hitting song, it will go into protect, but only for a second or two, then it will go back to normal. The amp gets hot also. Another thing was There was a reallllll low note and like it tried to go through the sub but couldn't or something like that so it went into protect and again, came right back after a second or two. Amp was hot.

It's a 1 ohms stable amp so why is it doing this? Is it because I have my subwoofer level from my head unit at +15 instead of 0? Or is it because I have the gain at about 25%? Any help would be great guys last thing I wanna do is mess something up.

Also the box moved so the amp was up next to my trunk wall, could that be the problem? Being in a close area made it get hot and it went into protect? If so, why does it come right back on and bump for a good while after that?

Your electrical can't handle the load. Are you running the stock alternator/battery?

Check your volts. Are you positive you have it wired to 1 ohm? I may run the same setup soon //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Stock alternator, and a battery I bought from autozone (so probably stock)

I was told 950watts@2ohms my car was going to be able to handle it. My lights were dimming yesterday tho, not my gauges with my speedometer, but my cabin light. I upgraded the big 3 with 4 gauge wire, which is what I was told would be plenty.

I have it wired 950W@2ohms, 1 ohm is 1500 watts no way I would run that.

I had a similar problem, with the same amp, at the same ohm load. It's possibly your ground. Also, check and make sure the mini anl fuse it comes with is screwed down snug. Not the allen screws holding the wire, the screws that actually hold down the fuse itself.

Well ****. What did you end up doing?

I guess I'll Check it's ground although I'm almost certain that it really snug, on metal, because I scrapped the paint off. I also tightened the screws on the fuse before I put it in, I noticed they was loose. This is really discouraging, I was happy that I had a nice loud *** system but there always gotta be something stopping me from having a nice system, that cost a lot of money. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

why do you have your sub level on hu @ +15? why not set it to 0 then reset amp gain

hell run stock alt and my amps dbl the size of yours(not talking bad about yours) and mine doesnt even kick protect. seems to me that it may be the fact your level is set kinda high

I thought this was the correct way to set your gain. Ensures highest possible voltage out of the rca's.

And, @Quick, did you set your gain w/ a dmm?

hm.... i have never heard or been told that before.... i was told set everything on your hu flat(all 0).... then set with dmm...

You're clipping the shit out of it because you're a noob. Use a DMM and set the gains CORRECTLY.

you turn your the sub level on your deck all the way up, and zero out everything else. the only thing the headunit's sub level control does is increase and decrease preout voltage.

I had it on 0 but the sub doesn't hardly budge it doesn't seem like.

Really? I don't wanna clip it that can hurt the subs. Can you suggest a DMM that won't break my bank? My dad has a meter because he works on air conditioners.. I'm guessing that wouldn't work tho?

ummm, even if you had it on zero, and then set your amp gain, it would still bang just as hard, lol. you would just have to turn your amp gain higher. Don't worry about that. keep it at +15. turn off bass boost. turn your equalizer setting to all 0's. then use a dmm to set your gains with a 50 hz test tone. do you know how? do you have a dmm? I think the problem is your electrical. most likely your ground. where is your ground?
