Amp gets really hot?!

[I Like Waffle]

MRP-M1000 stock electrical 110 alt. i have 0 GA running to my amp and a good ground.

My amp gets really hot and the subs get quite when its really hot.

That is alpines thermal protect feature. Output drops 6db to keep the amp from overheating too bad. Read your manual.

hey before you wire it up again please find out what impedence your amp is reading, take the measurement right from the + and - terminals on the amp... use your DMM with the ohm setting if you can figure that out.

I've seen -49 before, stupid northern latitudes...

Turn the gain down, youre clipping it. Mine only overheated when it was being clipped.

Well i had it hooked up one way and they told me it was wrong and it NEVER overheated before then... I went in to have my gain set and they told me it was fine...Im just going to hook hook it up like i had it before like in the rockford pic

Okay so i got my subs wired like that pic. they amp isn't as hot but gets pretty warm. So when i set my gain with a 0db tone the subs are not loud at ALL so someone told me to use a -3db tone and i have to have my gain maxed out to get it 46.9 volts. what could be the problem? i have a Alpine CDE-9874 2 volt pre out and like i said in the OP a MRP-M1000 alpine amp

I am useing a 50 hz tone

you need to go buy a digital multi meter from walmart and learn to use it.

i did that. I used a 50 hz tone at 0db and the subs are not loud at all now. i set it 46.9 volts, so then i tried using a -3db tone and i had to max the gain all the way out to get to 46.9. could that be my amp? i have a 0ga wire running to my amp but only a 100amp inline fuse. problem?

Anyone?

So should i use a -3db tone or a 0db tone? 50 or 60 hz? i use my iPod all the time on my deck so should i tune it with a tone on that or a CD Cds seem to play quite a bit louder.

When you set the gain using a 0db test tone, you are being overly safe in my opinion. Most music is not a 0db test tone. I think it MAY be safe to set it with a -6db tone on a cd. After you set it with a -3db or -6db tone, play a normal cd and if things seem to be distorting readjust.

I always use 40Hz @ -6dB. Here's the download link if you want it. MEGAUPLOAD - The leading online storage and file delivery service
