i hooked up my wires and a Panasonic ca100U HU and i built a box for my sub ....ok i hooked the wires to the sub and then i hooked the RCA's in last ....every tim i hook them up the PROTECT light comes on ....i got the HU wired right and everything else no wires toughing and so i thought , maybe it was defective RCA's so i bought new ones ....no luck im lost i've installed the same setup but with 2 Vegas and they worked GREAT but i cant even get my amp to come on....oh yeah i already tried a diff amp and sill no luck ...im runnin a Planet Audio 1200D amp with 1 "10 p1 RF punch sub

 

check the amps ohm ratings and make sure no wires are touching whatso ever and that the sub is wired correctly, all your positives, negatives ect.. also make sure your terminal isnt touching the pos and neg on the box on the inside

 

you have to make sure you wire the sub right (omes) you cant wire it for one ome if the amp cant handle it

 

Even if the speakers are wired at to low of an ohm load the amp should still come on. Try disconecting everything but the power, ground and remote turn on. Turn on the stereo an see if the ampo powers up correctly. Then turn off the stereo and hook up the rca and turn back on the radio and see what the amp does. Next try the speakers, hooking them up one at a time. This will help you setermine if its the amp, speakers or HU

 

it could be possible your remote lead is dead or your ground isnt grounded properly or many things...Im sure youll find the problem.

You can make a remote lead from a switch and prolly even run it to your cig tray...

yea having teh hu turn it on is mearly a conveniance
... check all ur connections 3 times

 

well i had the ground grounded to the plastic on the jack ( i got a 4th gen Z now) and i didnt realize it ....but im interested in how you wire it for ohms ....i knew they were rated, so i have a 2 ohm x 2 or 4 ohmx1 (bridged) and a RF P1 4 ohm sub now do i need to do anything more???

theres the site for how to wire a sub properly..

If you kno what your sub puts out at say "500w at 2 ohm" then if your sub is 500 rms then you would want to wire your sub to 2 ohms.. you kno what im sayen.. just wire the sub right for the amp and you wont have problems
