I just got a kicker zx850.2. So i took out my old amp, witch was some old legasy, that sounded good, but i wanted something better. and i wired it up just fine, But it sounds like ****, I have it hooked up to two 10in. 1042w infinitys. And there was not much lows, they did not hit near as hard as they did befor,and this is a much biger amp. They really did not sound good at all, so what do i need to do, what should all my settings be at, Or do i need something els.... Thanks

 

try turning up the gain on the amp

 

No, let's not start by turning up the gain. Once again, not a volume ****. Start by checking the crossover setting on the amp or head unit, whichever you are using. A good place to start is to set the sub for around 80hz lowpass. Check all your connections and make sure the amp is getting the proper voltage.

How do you have it hooked up now? One sub per channel? Both subs wired together running to a bridged channel? Also, how are the subs wired?

 

I have played with all the settings and if i give it to much gain, or bass boost it just makes it sound worse, and the subs sound like they are going to blow apart, And there not very low, they move a lot but i'm just not hearing the lows i did with my other amp.Everything is tight, Where are the crossover settings at?
I have each sub hooked up to it's own channel. How should i have it? The subs are 4ohms, and i forget how i have them wired because i cant see them in there box i think i wired them like this, should i change them?

 

The Kicker amp is rated at 425 watts @ 2ohm or 850 bridged @ 4ohm. Your subs are dual 4 ohm voice coil subs. If you have them wired as you say, each sub should be getting the 425 watts and should be sounding really good. The crossover setting should be either right on the top of the amp or on the end plate. Do you have a crossover on your head unit too? Either way, you need to make sure the crossover is set to low pass and start at around 80-100 Hz. It almost sounds like maybe the crossover is set to high pass so, that is the first thing I would check.

 

Ok so I have it wired up right? or should i do it another way? Well my cross over goes from 50 - 200 Hz, and i have it a little over 50. my cross over is set to low pass. I dont know if my head unit has crossover to, how would i find that, because i dont see anything that sayes crossover in my EQ, Also right now i am useing 8 gage wire, I plan on geting 0 ga. will i notic any change??... thanks

 

The subs are wired fine. You could wire them together and bridge the amp but, you will not see a power difference. I try turning the crossover up to around 100Hz. Right now, your subs are only playing frequencies below 50Hz. That does not cover a lot. Just changing that may make a difference.


What kind of head unit do you have? Model and Make?

 

Alright i will try that, i have moved it around and it has not helped, the subs move like crazy, and it seems like they are moving to much, but theres just no sound to go along with them, and my rear veiw does not shake verry much, and with my other amp i could not see anything in it. where should i have my gain and bass boost at?
I have the sony MEX-1GP

 

Also, I have my subs in kinda small boxes, that are sealed. They sounded good with the other amp, but could they need more air space since i have a bigger amp now. Or does that not matter? thanks

 

Is it a different box than what you had before or same box? I looked up your head unit and it does have subwoofer controls. You may have to look thru its manual to make sure the settings are correct for it.

 

Hmmm, wired out of phase-for the worse?

Let me ponder this...till tomorrow

 

yes there the same box, But it just sounds like it needs more air space. Yeah i have played with the sub controls, and it better when i turn that all the way up.... and also would a copacitor help out or do anything for it??

 

Well let me know i need all the help i can get... Thanks

 

Cap will not help. Wired out of phase could do it. Meaning basically one sub is moving in while the other is moving out and vice versa. Make sure both subs move in and out at the same time.

 

so if that is what is wrong, how do i fix it?
