Question about Kicker (ZX750.1) Car Audio Amplifier

1 Answer

No output My amplifier is hooked up correctly and the green power light is on. I don't get any bass out of the subwoofer unless I turn the gains all the way up. It was working fine for about 2 months. I have 13.5vDC at the positive and negative terminals. I tested my subwoofer on another amplifier and it works fine. What could be the problem?

The output input cables try that first

SOURCE: No power output

Set the meter to AC volts and measure the AC voltage on the RCA cables where they plug into the amplifier. The black meter leat will go on the shield ground of the RCA cable. The red lead on the center conductor. You may have to turn the volume up to get a reading on the meter. At high volume, you should read at least one volt but the actual voltage will vary due to the audio signal. If you get no voltage on the RCAs, measure the AC voltage on the input to the LOC. Let me know what you find.

SOURCE: i have a kicker 750.1 amplifier. I was playing it

I would say that your subwoofer Or speaker leads have shorted out...when the bass hits as you say it drives the amp hard but if it is trying to dump power onto a shorted speaker or speaker wires it will blow the output power transistors not to mention other vital components of the power amp...i suggest you test your speaker leads with a Multimeter on the ohm setting before connecting a repaires or another amp.. to make sure there is no short on the leads and that the resistance is around 4 ohms or so depending on how you have your drivers wired...but anything lower than 2 ohms will cook an amp! you can normally pick up a meter from anywhere for around $10..

Have you checked the fuses inside the amp?Unscrew the cover and with the amp sitting on its back,remove the cover.You have 2-4 fuses,old round type,in there.

Can i use my jensen jxp340 amp with my one 800watt 12" 4 ohm subwoofer?


Yes, technically you can, however you will be putting both your sub and your amp at risk. One of the worst things you can do to a sub is underpower it. The easiest way to explain it is n ot giving enough power to the sub leaves it starving for power. The motor structure ends up working too hard to try and move the cone properly and what happens is the sub will usually seize up rather than blowing out in the term you usually hear (ie, I had my system cranked up and I blew my subwoofer).

Secondly, in an attempt to get any real sound out of the under powered sub, you'll probably end up cranking the gain and bass boost on the amp which ends up overworking the amplifier quite a bit and can in turn lead to fried out amp chips, burnt up circuit boards etc.

Thirdly, by maxing the gain bass boost you're going to end sending a lot of distortion through your subwoofer in an attempt to get some decent bass. Distortion kills both subwoofers and speakers alike.

So to answer your question, yes you can hook up your subwoofer to that amp and yes, it will probably play for a while but I wouldn't recommend it. Look for a class d or mono block amp to push your sub as these will give you the most power and best heat dissipation. They are designed to push subwoofers specifically and you will get better sound and longer life out of your equipment. A good rule of thumb is look for an amp within 100-150 watts of both your RMS power handling and your Peak power. Remember, when it doubt, always go a little bigger on the amp side of the spectrum. It's easy to "tune down" an amp by having the gain and bass boost at a lower level (50%, 25% etc), than to turn 'em all the way up just to get some bass and end up prematurely blowing out your sub, amp or even worse, both.

NO BASS!!


1) Check the Subwoofer for continuity - At the subwoofer, one at a time, test the terminals for Continuity using your Digital Multi-Meter; if your DMM doesn't have a Continuity test, use the Resistance, or Ohms, test and check for Resistance in the Subwoofer Coil (be sure to disconnect the subwoofer wiring before performing these tests).
2) If they test out good, hook the wires back up and test the terminals at the terminal cup or at the Amp hookup if you didn’t use a terminal, don't hook it up to the amp yet. Sometimes the wiring inside the box can be a problem if it has come loose, or isn't making a great connection.
3) If you have a Sub or multiple Subs with Dual Voice Coils, or multiple Subs with Single Voice Coils, make sure your wiring is correct by checking here:
http://www.the12volt.com/caraudio/woofer_configurations.asp
4) Make sure there are no Hi-Pass filters, crossovers, or multi Channel switches enabled.
5) Replace your RCA cable/s with known working RCA cable/s from the Source/Head Unit to the Amplifier/s.
6) Check your Head Unit settings; make sure the Bass is turned up and/or the Subwoofer setting is turned On.
7) If you are still getting no or low output, try plugging in an MP3 player or CD player using a headphone to RCA adaptor and check for sound output. If there is still no or low output, your Amplifier outputs are probably burned out.

Only powers subwoofers when at high volume


Well, make sure that the output level on your head unit is up, and also try adjusting the gain NEVER EVER PUT IT ON FULL GAIN BECAUSE THAT WILL CLIP THE AMP AND MAY BLOW AMP AND/OR SUB!!!

Is this powering speakers or subwoofer? If it's the subwoofer you need to make sure the gain is turned up and the sub is set to low pass frequency. Also make sure bass and subwoofer are enabled on the head deck. Make sure the RCA's are hooked up properly at the back of the head deck. If it's the speakers then you may have balance set to front only so your rear speakers aren't making noise.

Amp is on, but sub wont produce any bass


Make sure the subwoofer is set to low frequency, make sure subwoofer and bass are enabled on the headdeck. Make sure the gain is turned up on the amp, make sure the rcas haven't come out of the back of the head deck.

What head unit do you have?
Is there a dedicated subwoofer output?
If not, have you switched the rear output to sub output?
Is the amplifier set to LPF (low pass filter), and the gain turned up?
Many things can be wrong, but the fact that there is anything coming out of the subs is a good thing.
Start at the beginning - Head unit, then check amplifier gain/crossover setting.
If you are using a hi level adapter on factory radio, is the Bass on the radio up? is the output gain on the convertor up?

they are to adjust output levels. yes you can hook up the sub to the amp. it is not wise to hook up the front speakers with the sub though. just get a less powered amp to drive the front speakers.
