Sundown 1500 on 4 gauge make THAT MUCH of a difference?

[srch4aresn 10+ year member]

i have a caprice with 140amp alternator with big3 (4 gauge) and 4 gauge wires. my old system was a jl 500/1 and a jl 300/4 with no problems. to help sell the car i put in rockford 500.1 and rockford 400.4 still with no problems. got a dc lvl 4 15 and hooked that up to the rockford 500 temporarily and it sounds great. nice and loud.

so i buy a sundown 1500.1 on here. i hook it up in my car (to test) and theres literally next to no sound coming out. it powers on, no protection mode, but the sub isn't even moving. i wire the sub down to 1 ohm and turn the gain all the way up. still barely moving and not doing anything.

would having 4 gauge cause that much of a difference to where this normally powerhouse amp to barely move my sub? the rockford 500 moves this much harder than the sundown which isn't right.

ive checked all the connections, checked if maybe the rcas were in backwards, checked the subs wiring, nothing else is a variable besides the 4 gauge making restricting power that much to where the amp can't do anything.

also, when i hooked the power/ground up to the amp, it didn't spark?

You should be able to get output from the amp with 4 ga wire, 4ga ofc is good for 150 amps @ 20 ft... I wouldn't want to run it like that daily - I would definitely upgrade, but should be sufficient for a quick test...

It's definately not because of the 4 guage. Maybe the amp is blown. I ran 4 guage on my kicker zx1500.1. I eventually switched the 0 guage but didn't notice any kind of difference

thank you very much for this. I hooked the rockford 500 back up and everything is working as it should.

I'm going to give it one last shot then take it from there

all the wiring does is help the flow of electricity from your engine bay to your amp, so i highly doubt that it's because you're using 4g. i'd open the amp and see if anything looks blown/weird in there.

from the sound of it when you say it didn't spark i wanna say that the amp is bad

i will offer more help in trade for your caprice //content.invisioncic.com/y282845/emoticons/naughty.gif.94359f346c0f1259df8038d60b41863e.gif

check the wire that connects the rca's to the board of the amplifier. my saz 1500 had that problem.

ya id say open up the amp, sounds like something has gone wrong inside there. My rockford 500 had one small piece broken on the board inside causing whole amp not to provide power. Completely different amp sounds like a similar problem though best of luck to ya man great amp ***** you haven't got to enjoy it yet though

What size is your fuse?

What size is your fuse?

That still wouldn't cause the issue he is describing, definitely something going on with the amp....
