Amplifier keeps going into protection mode?

[LethalProphecy]

I have been having a ton of problems with my sub-woofer system lately. I have two SoundSplinter RL-i DVC 4 ohm 12" subwoofers. They are wired to 4 ohms in a sealed box. Before I had them wired to 1ohm on a PLA3100D, and I kept the gain at max, before realizing that my 5awg power and ground wire is way to small for such an amplifier it quickly fried the amp up and I am now forced to use my Hypnotic V1500DX. Since it is not 1 ohm stable I wired my subwoofers to 4 ohms. This means it is putting out about 750W RMS x 1 Channel. I also have a 300W RMS amp for all of my other speakers on the same power wire. It is split up with a distributor in the trunk with 100a and 150a fuses respectively. Set up the way it is, it is my understanding that the hypnotic amp should be able to function at full gain and bass boost, even on 5awg wire without shutting off(I could be way wrong). If I turn the volume up and let it run for a little while it will shut off eventually for about 2 seconds and turn back on only to do it again in the next minute. I've checked the amps temp with my hand as soon as it shuts off and it honestly is not that hot so I don't think its from thermal protection. I have a red top optima in the hood and the lights used to dim severely from the Pyle amp yet it would play continuously but they do not dim on the Hypnotic amp at all even at full volume so I don't believe its low voltage protection. I have tried messing with the gain and bass boost and it doesn't make much of a difference the amp still shuts off at high volume (usually around big bass notes). My plan is to get 2awg wire installed but I want to make sure that will fix my problem instead of wasting my time. Has anyone else had similar problems or know the solution? Thanks in advance.

You are alll fcked up dood. You cannot just crank the gain and bass boost knobs, that is not how it works...... You are probably completely killing those beautiful subwoofers. Do some research on how to set amplifiers correctly.

Get a better amp before you ruin your subs. Should be 1 ohms stable @2000rms. or 4 ohmsstable @ 2000rms. and you need to do the Big 3 no matter what. Otherwise you might as well toss those subs in the trash cuz you going to put them to death soon enough

you really need to know how to use an amp first

X2, look for a "how do I recone these" thread soon enough

I was thinking more along the line of "my subs are making a weird scratching noise"

And what a sad thread that would be.... I love those subs.

if if actually gets into your head that you need to do the big 3 yank the walmart wire out of the car and put in some real 1/0 so it can actually handle the power

For starters. Get some good power and ground wire. Second go get a different amp. Find something (like subzero said) that runs 2k RMS(not max) at 1ohm or 4ohm. Question it on the forums first if you aren't sure what your getting yourself into, most of the people on here are pretty easy to work with and are willing to help out if you ask. If there is anything else that you need to know, like I said just post it on the forum and most likely someone will help you out.

His main issue right now is not the wiring or the amp, it is how he is setting the amp. Regardless of what amp and wiring you have, you are going to keep blowing shit if you max out the gain and bass boost.

He also needs to get an amp that doesnt only push 750 watts so he can learn on how to tune it instead of having it all the way up so he can move the subs slightly.

I don't think the OP is even reading the suggestions here...I wouldn't bother guys. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

your right nobody was of any help. Thanks anyways guys. The local audio shop alpha omega installed some 2 awg for me and it works perfectly.

Gain should never be at max... you're probably clipping the shit out of the amp
