i posted a month ago about my kicker l7 and my kicker zx750.1 amp it keeps going into protect and i cant figure out why it worked fine at first but messed up but any way i had another system in my car it was a mtx system and it went into protection and the guy that installed my amp and subs told me my amp was ****ed up and it worked fine in another friends vehicle i had that mtx system hooked up tyo my stock head unit and the guy had to put in a device in so i can have rca jacks and he ran my remote wire rly ****ed up and recently my key got stuck in the ignition and i had my kicker shit in my car and the guy at rameys told me the remote wire was making a fuse keep blowing do you think that could be what makes it go into protection mode and it only works at low volumes when i turn it up it goes into protect please help

you need to know for sure, if it's wired t 2 ohms you shouldn't have a problem,(d4) but if it's a d2 then it may be wired to 1 which will def. put the amp into protect

this will show you how to get the disired 2 ohm load, if it's a dual 4

take the sub out, use the link, and make sure it's wired correctly... that's where i'd start...

always better to be absolutely sure than pretty sure, if thats not it idk... check grounds, connections... maybe someone else will chime in...

Dammit dude, learn to use periods and punctuation in your sentences. Reading your initial post hurts my brain, and I have a ME degree....that's saying something.

Make sure the power is wired directly to battery, the grounds are all good (for the HU and amp both), and the remote wire is wired directly to the HU. Also be sure the remote wire isn't being pinched by your seats or any other hardware and it's not shorting out anywhere. Also make sure your amp is getting good air circulation.

From the sounds of it, after reading your retarded first post about three times, it seems like the amps work in your friend's cars but not yours. That rules out the possibility that the amp has a problem. I'd also check that your antenna connector is properly installed in the HU, as that is a ground point for many older cars. In my Maxima, for example, if the antenna is not connected the HU will not turn on at all, and neither will the amp.

Ok heres what i've done so far. I changed the power wire,grounds,and ran the remote wire directly to the hu. my antenna connector does not fit in my stero but i was having the same protection probleam with my old stock head unit. I also bought brand new rca's and it also didnt help it. I looked at how it was wired it was wired correctly at 2 ohm load in the box i told you all wrong too my speaker is a 4 ohm kicker l7 dvc. My power wire and ground wire is 6 gauge if that helps and yesterday my friend ran sum speaker wire from his amp and i ran sum from my sub and connected the two speaker wire and the sub was making his amp go into protect but he has a 600 watt power bass amp.

O yea about that antenna not fitting my car is a 2007 Chevorlet Cobalt Lt you think that would affect me? and it was hooked up to my stock hu which the remote wire was ran rly weird cause my stock hu didnt have a place in the back of it for rcas and remote wire he had to put a device in it for the rcas as well.
