I just installed my 800prs headunit and it looks fine. I currently only have midbass speakers hooked up in my doors running off of a sundown 100.2. The problem is when I turn on the car the sundown lights up red (protect) for a second then it just goes away and there's no light. Any ideas?

Here's a breakdown of my wiring. I re-ran everything and cleaned it up. 0gauge from front battery + fuse to rear battery which is fused at that end as well. 2nd battery 0gauge ran to a distro, 4gauge from the distro to the amp. 4gauge ground to a distro (maybe the problem?), 4gauge ground ran to the amp. I have the remote (regular speaker cable) running from the front.

the 4ga is okay bud for the sundown.i think you have to make your ground as big as your runs?=)

just a random thought, but did you DMM your power? or your remote, thought i read somewhere that someone did have enough power flowing through his remote and it sounded similiar.

I don't have a dmm but I was thinking that might be the problem too. How can I send a stronger signal through the remote wire?

Bigger remote wire?

I put a thicker remote wire in and checked the front speakers to make sure they weren't touching anything metal and I'm still having the same problem. Any suggestions?

how is your rear battery grounded?

Messed with it some more last night. The rear battery is grounded fine. I checked the front midbass speakers and terminals are fine, ran a thicker remote wire and when that didn't work I ran a ground and power directly to the 2nd battery (instead of through distro's) and everything worked fine. I decided to re-do all of my wiring and go directly to my battery with my amp. I re-routed everything and mounted everything and now the amp is doing the same thing (turning red for a few seconds when I first turn on the car or ACC, then the protection/power light turns off). WTF.....My rear battery is grounded well and the 3way xover in back lights up fine. I'm stumped!

is the speaker wire ok? no bare spots? have you tried disconnecting the speakers from the amp and see if it still happens? try removing the speaker wire from the amp first, if it still goes out, try unhooking one terminal each from the speaker directly. if it is still going out, then you know it's not speaker/speaker wire caused.

have you tried going from the battery to the remote turn on? completely bypassing the h/u turn on. see if the amp lights that way. you might have to run a relay in line with the turn on, especially if you ae turning on multipule items.

Thanks for the help, I'll try that out after work. Does the remote just go from the positive battery terminal? Could I run the remote wire from my rear battery?

yes. it just wont turn off.

if this does solve your problem

just wire in a switch

or look into a relay. again, it could be an issue of too many things being turned on. you could also find a 12volt switched source and wire directly to that. i would do the relay though.

and beerdrmkr...you could also jsut unhook the remote turn on from the amp and simply jump from the positive input over to the remote input. that would be the easiest way.

I'll just try from the rear battery first and see if that works instead of digging out the wire and taking out my hu. Thanks

Exactly how is your rear bat and amp grounded? The fact that you ran a ground from front bat to back bat and everything worked fine indicates you probably have your rear grounded incorrectly.

Give details on ground path (from what to what) and guage size.
