Yes, why are you sending two rca channels into a single rca input on the amplifier? Channels 1 and 2 should be front left and right, and channels 3 and 4 should be rear left and right. Any bridging should occur on your amplifier-speaker connections, not on your head unit-amplifier connections.
Edit: although, as you have 4 input channels (4 RCA's run to your amp), there should be no bridging. And if you have RCA inputs, why are your rear two channels set to "high?" Cool name, btw.
I don't understand "there is only one front input;" please type clearly, in full sentences that fully convey what you're trying to say. Do you mean that the amp only has 1 input? Because that isn't true, it has has 4 inputs (front left, front right, rear left, rear right, hence being a four channel amplifier). It also has 4 outputs. You need to sit down with the manual and learn how exactly your amp works and what the settings do, or you need to go to an audio shop. If you are only running one pair of components, then you don't need 4 rca cables going into the amp, you only need two. Are you trying to bridge the amplifier into a two channel? If so, you seem to have it wired incorrectly; look at page 15 of your manual to see how to bridge channels of your amp. There are so many things wrong right now.
Explain your full setup, i.e: I have a headunit. I have this 4 channel amplifier. I am running a single pair of components, using the passive crossovers. Give details. Give us something to go off. I can tell you right now that having 4 RCAs with Y-adapters into two channels is incorrect for sure.
Ok. I dont want l to bridge. There is only 1 front input. The other is labelled rear. The other is preout. This is why I posted as detailed a pic as I could.
I've read the manual 3 times front to back. It's convoluted at best.
I have an Eclipse AVN5510 HU and only want to use 2 channels to power my passive HAT Clarus up front. I'll leave the other 2 channels empty for now.
I think you might want to go to an audio shop, if you can't figure out clearly written instructions. I have the manual pulled up from JL's website, and it looks fine to me, definitely simple enough. And again, you have multiple issues going on.
OK, so first of all, if you want to power 1 pair of components, which is only 2 channels of audio (one left and one right), why are there 4 channels of RCAs coming into the amplifier? There should be one pair of RCAs, because you are only needing the signal for the front two channels. You should only be using one pair of RCA's coming into this amplifier. There should be one set of RCA's coming out of the back of your headunit. Use only the "Line Out/F" to send a signal to this amplifier. At the amplifier end, plug them into the corresponding front L & R jacks on the amplifier. This should fix your first issue. Remove the other random pair of rca cables, and for god's sake get rid of those stupid useless Y connectors. THEN, you need to follow your manual and correctly set the gains. Make sure that all crossovers are turned off, both on your amp and in your headunit. This will fix your issue. You really should take it to a professional, because otherwise there is a very real chance that you will blow your speakers. Also, have him tidy up that ghetto install.
Why do you have a 4 channel amplifier, but you are only using two channels, and not even bridging? It doesn't hurt anything the way you're doing it, but you spent all that money (it's an $800 amp!), it's taking up all that weight and space, and you aren't using much of its capability. It's like buying a Porsche just to drive down a neighborhood street to the grocery store once a week.
As an aside, whatever is written on the amp is meaningless, with regards to front or rear. Just because it says rear, doesn't mean you have to use it for the rear; it's just there for convention. For example, you could take the rca cables that are plugged into the "Line Out / F" of the Eclipse, and plug them into your JL in the "rear" input. Then, as long as you used the "rear" controls, and the "rear"-marked terminals on your amp for your HATs, everything would work fine. It's not like something will blow up if you plug something marked "front" into "rear." For example, if I went out to my car and swapped the RCA's around, all that would happen is that my fader would work backwards.

Having to turn volume to 45 to get normal listening levels powering HAT Clarus (passive).
See connection pics below:
Are my connections / settings wrong?
See on the bottom pick where it says 2 channel input/4 channel input?
Select two channel fade radio left see what two channels bridged has music playing thats gonna be your left side the other will be right.
Your amp has the ability to be bridged without the use of any y connecters.
It's signal summing and it's one if the reason why jl included it. Simple set up.
"What screws us up the most in life is the picture in our head of how it is supposed to be."
The system was first installed by a shop a couple years ago. It turns out the RCAs were labelelled front left and right but I've since figured that was wrong. My ignorance coupled with their mistake. They are front, rear and subwoofer. So I have left the rears unplugged for now.
Getting sound but I still have to turn the HU up to half of full volume to get normal listening volume.
I want to keep it as simple as possible for now and not bridge them. I will then take it to a shop to have them set the gains properly.
The ghetto install is purely just for testing. If you saw my build thread you'd see I would never allow this sort of setup to be permanent.
