Was it OK before with the same connection some time back ?.
You have not mentioned which sub woofer you are using. Any way check the following:
The head unit has 2 sets of RCA out labeled front out and rear out. Then it will have a single RCA out labeled sub woofer.
Your door speakers must be connected to the front and rear out if you have a 4 channel amplifier.
Now your Kicker zx750 is a very powerful amplifier ( 750 watts r.m.s ). Make sure your sub woofer has the same power rating or more.Set your crossover to about 80 Hz and turn on the subsonic filter for the time being.Turn down the Bass boost control to zero.On the head unit keep the sub woofer level to half.
Now with the boot and door closed play some music and see how it sound and if not satisfied turn up the bass level using the Kicker's wired remote control. It should work ok. Cheers !!

Hooking up two amps together


Yes. There could be big issues depending on how you want to "hook" them together. If you are wanting to simply run them at the same time (play through both at once) you can get a cheap signal splitter from GC or Radioshack and run your bass to the input, then output 1 and 2 to the respective amps. That is your best bet.
Setting up two amps parrallel does not nessesarily add power. That is to say that your 150 and your 350 "hooked" together does not give you 500 watts. In addition, there may be some issues with running a powered signal from the first amp into an input that is not designed for powered signals. Try the splitter or an old fashioned AB box. Safe and a cool trick. You can also use a stereo chorus pedal and let the signal chorus between amps. Makes the bass sound huge! Try it and good luck.

HI CAN YOU PLEASE TELL ME WHY MY FENDER RUMBLE 100 BASS AMP DISTORTS AT LOW VOLUME? EVEN THOUGH THE SPEAKERS IS NOT BLOWN


A common reason for 'distortion' with all bass amps can be either that the screws holding the speaker unit to the cabinet have worked loose or that there has been a build up of dust particles in the corrugations around the edge of the speaker cone, which rattle especially on the lower notes.
The solution is simple - remove the front grille and check the screws are tight. Use a vacuum cleaner to remove dust from the rim of the speaker cone.

Speaker has become crackly, only when i play certain notes though. I tried a different cord and bass and its definitely the amp. I have never turned the volume over three quarters, Should I just switch out...


Before changing the speaker, check for debris or other things in the cabinet or grill that MIGHT be rattling..

Also, plug in an external speaker to the ext jack and see if it is clean.

How do i wire in a Zn-4088 Xlopd sub/amp?


I also bought one and it came with no instructions either.

Should be pretty simple but if you want to control the On/Off of it by the head unit you will need to use a relay,

Similar prob.did the 12 steps on how to install amp(jensen4100,blue).red protec light comes on when starting car then goes out and is not followed up by the green protec light .green one never comes on....


If you are running a set or a single subwoofer with the jensen amp than you will want to hook up the rca cord to the subwoofer rca connection on the back of the stereo unit-the other rca outputs are there in the event that you want to run a 2 or 4 channel amp to power the speakers that are generally located in the doors or back deck-with that set up properly you would still be able to adjust the balance and the fader just as though you were powering the speakers with the deck. Pug the free ends of the RCA cord into the input rca receptacles of the amp- the stereo now will feed a signal to the amplifier that only contains bass - good luck

Fender Rumble 100 210 pop noise then hum after strong low e note


I just fixed my bass amp with a similar problem last week: the problem is related to a loose connection on the PCB board (likely).
A bass amp is a rough place for circuitry: the low rumble and power shake a bass amp more than a guitar amp.
In my case, the power transistors needed to be re-soldered and then the grounding bolts and screws needed to be removed and cleaned because the connection was bad. Remember that when two different metals needed for an electric connection are toughing, there is the likelyhood that corrosion WILL happen.
My bass amp did basically the same thing yours did: sounded good at low volumes, but at higher volumes it would act up.
In short, there is nothing you can do (unless you are a repair person): you need to take it to a local music shop and have a tech fix the intermittant contact problem: someone who knows what they are doing should only take an hour at most.

Hope that helps!

Still no sub woofer output


SET THE CROSSOVER TO "L.P.F."POSITION AND SELECT THE LOWEST FREQUENCY AS THE CROSSOVER POINT.
[AN AMPLIFIER IS SUPPOSED TO "AMPLIFY"(TO INCREASE)ANY OUTPUT.]

TRY CHANGING THE POLARITY OF WIRES FROM AMPLIFIER TO SPEAKERS /SUBWOOFER.{it leads to cancellation of bass output.}
if u still have doubt contact me again.

Amp cuts off


So you have an EQ and a Pioneer amp you're trying to hook up to each other? And only some Stinger RCA cable works? And when the lightning audio RCA cable is hooked up, it doesn't turn on? The amp isn't grounding itself through the RCA cables, is it? Check your ground wire and make sure it has a clean contact that's free of rust or any paint that might be in the way. Otherwise, the RCA cables should have nothing to do with an amp turning on or not.
