I have a kicker solobarik L5 and a zx 400.1 kicker amp. I have a stock radio without any rca outputs so I had to hook up a rca line adapter. The sub hits sometimes. It is always on. I can see the sub working but as I push the gas, speed up, slow down, idle and push the clutch in it gives me different levels of hit.Sometimes it slams to its potential, but the next second it wont it will only be very light. Any help

Re: sub not hitting constantly
The big speakers have wires from the frame to the voice coil. After longer use at higher volumes (or longer travel), the wire can fracture, and make contact only some of the time..line on a bounce or knock.

MY BEST GUESS FROM WHAT YOU HAVE SAID IS THAT THE BOX WAS TO SMALL. BUT YOU ARE OVERPOWERING THE SUB RUNNING IT AT 2 OHMS ON A 750 WATT AMP WITH A SUB THAT IS ONLY RATED FOR 600. NO MATTER HOW FAR YOU TURN YOUR SETTINGS DOWN, YOUR STILL PUSHING TO MUCH POWER FOR THE SUB TO HANDLE. IT IS ONLY RATED 600 WATTS FOR A REASON. ESPECIALLY IF YOU LISTEN TO MUSIC THAT HAS A REAL LOW END AND THEN A HARD HIT. REMEMBER A HARD HIT WILL SPIKE YOUR AMPS OUTPUT THEREFORE PUSHING MORE WATTAGE TO THE SUB.
If you are referring to the Kicker L5 solo-baric subwoofer, then an 800 watt peak amp will not blow even one of those subs. The L5 is capable of handling 1000 watts peak and 500 wrms. An 800 watt peak amp will usually have around 400 wrms. Underpowering the subwoofer will not hurt the amp or the sub(s).
You should never connect a load of an impedance less than the min the amp is able to drive. This can have disastrous consequences that may easily result in failure of the amps output stages. You need to use a different configuration that does not overload the amp in this manner for safe operation.
it must be reversed polarity in coil voices of speakers check + - wires from amplifiers fit on coil voices of speakers try to get each speaker to 8 ohms wiring in serial the two coil voices n'd put in paralel both speakers in bridge mode output from amplifier to get most stable power ,
Well, to get the maximum power from the amp, you really need a 2ω load. Unfortunately, you cannot get that from 2 L5's with 4ω voice coils. You can get either 1ω which will burn your amp up, or you can get 4ω, and your amp will put about 500 watts RMS into that load.
To get the most from your amp, you really needed the L5's with 2ω voice coils. That way, you could run the voice coils in series and the subs in parallel, resulting in a 2ω load, exactly what your amp likes. If you can exchange them for the 2ω model, I would.
Here's the link to Kicker's manual for the ZX-1000.
RCA output level and speaker level output have different voltages and currents. The problem you are describing is common to folks trying to connect an OEM dash unit to an aftermarket amp. If your amp has speaker level inputs, try wiring to those......best bet..buy a new head unit, it'll sound better...louder and cleaner.
My recommendation is to get a line level converter. Go to a car audio shop or even best buy and specifically ask for a line level converter. It will have speaker wires in and RCAs out. Connect the speaker wires to the sub woofer speaker wires and then you will have the RCAs to run to your amp. I hope this helped.
