Speakers cutting out

[ArcFault 10+ year member]

Hey I just bought an Alipine amp, 750watts and two 10" subs. MTX something I posted a link to the exact speakers I bought.

http://www.futureshop.ca/catalog/proddetail.asp?sku_id=0665000FS10085244&catid=11051&logon=&langid=EN

I hooked them up but once I get to a certain volume level the speakers both kick out. But then kick back on and kick out on and off.

And I am not loud at all. I am not even past how loud my old 75watt amp went.

If I keep the volume lower the subs wrk fine. Unless a really loud beat hits.

Umm, only things I can think of that may be causing this is, my wiring is the same wiring that was hooked up to the 75 watt amp. Also, it is not directly hooked up to the battery... Could either of those be the problem.

then whats the positive wire running to? the alt? lol

Fuse pannel. I reckon it is... Somewhere under the dash...

run it right to the battery. and use at least 8 gauge for 750 watts. id do 4 but either one will do fine

and make ur ground no smaller than what u use for power wire.

ex. if 8 guage power use 8 gauge ground

if 4 gauge power use 4 gauge ground

So are you saying that, to small of a gauge of wire and not being directly to the battery could cause my problem?

I am really at a loss for this.

Yes because the current wire that you are using is most likely unable to handle the current.

this. u need to have big enough wire to carry enough current

rule of thumb to go by

0-500 = 8 gauge power/ground

500-1000= 4 gauge power/ground

1000 and up = 1/0 wire power/ground

So the speakers stop working because the loud volume requires more power and the small wire I have is not able to carry it...? It's not super small it's like 10 maybe... Also, how big does the Control wire need to be?

 

[basscort2009 5,000+ posts]

yea you need bigger wire like we said already. and control wire as in the blue one from the head unit? also known as remote wire. that can be small like 14-18 gauge

do you have it wired to the right ohm load? And do you have a good ground

I think my ground is good. I did not change any of the wiring methods.. I just switched the amp and speakers. And yeah, I meant the blue wire... It is like 12 gauge on mine.

What does the ground wire have to do with it?

How do I set Ohm load?

 

[slapperz 10+ year member]

Mine used to cut out because of the ohm load. I had it wired to 1 ohm when my amp wasnt stable. Check that
