i just bought a 1600 watts SPL z2x-1600 to go with the 2 15" inch subs i got in the back.... every once in a while the subs shut off, doesnt it alot more when i hit the brakes hard.... this ever happen to anyone????

 

its most likely going to be a lose connection on your amp did you make sure you got a good ground? Also is it mounted so it wont move around when you brake hard?

 

update on the amp turning off... it works great and the thump on the freakin thing jesus christ, but after about 10 to 15 mins of blasting it, they turn off.. watched it while i was cranking it and the amp light goes off, after a couple seconds it comes back on and still hits great but then off again. the power wire i took the driver side fender wall out and ran it through there... the ground i have it grounded to the seat belt bolt is that a good place for it???? where did everyone ground theres???

 

what are the specs on that amp how are the subs wired to it parallel or series? Is that amp 2ohm stable? Is it bridged also what size power wire are you using?

 

ok i just found the specs.

Is this your amp ifso i dont think you would be same briding the amp into 2ohms best way for you would be to wire the subs one off each channel in stereo. If you have the amp briged thats probably why it keeps cutting out.

 

thanks for all the help, i lowered the amp about half way instead of the whole way up, i also bridged the speakers and hasnt shut off on me anymore.....
