You need to turn DOWN your LPF....(low pass filter). You are driving the sub with a higher Hz than it is rated for. If your amp (or head unit) doesn't have a good LPF, then you are going to do damage to the sub over time.

How do I tune my KICKER 08ZX1000? I have the amp running to alpine type r 12 inchs at 2 ohms but I don't know where the bass boost , gain, and crossover knobs should be pointing or what one to turn up...


To start, turn the gains on your amp all the way down. Bass boost should be off (this us used if you listen to your subs at low volume, the boost will heat your amp up quick if you use at high volume). Then turn the volume on your headunit up to 3/4 full. Make sure the filter on your amp is on low pass. The crossover point should be at it's lowest too. With all these in place, you can begin turning up the gain. You will have to decide at what point to move the crossover point. Since there are different styles of music, you will have to listen to where you feel notes are "dropping off" from the music. Adjust the crossover point to your liking, but remember that subs were made to reproduce low frequencies. Hope this helps

Thought id got to good of a deal .just bought 2 9102d amps off ebay the add didn't state fact refurb thought ok .had old 821 on 2 12'' orion hps 4ohm dvc each is 2 ohm wired fact in fact tuned...


The amplifiers should certainly be able to handle 2 ohm loads so there is no issue there. I would suggest using a multimeter set to ohms, and measure the subwoofers to make sure they're still at 2 ohms each. Check your ground connections to ensure they're secure and reading as actual ground. Also, if you're just now tuning these amps to your system for the first time, set the gain at the lowest level that generates sound when your head unit volume is 3/4 of the max that you comfortably listen at. Use that as a starting point, and with a bass heavy track (if that's what you're into) slowly turn the gain up until you notice distortion, and then back off a bit. When you say you turn up 1/4 of the way, I'm not sure if you're talking about the amp gain or your head unit's volume. Also, your bass boost should be all the way down, and your LPF should ideally be no higher than 80 to 90 Hz. Hopefully your mids can offset the difference so you don't have a sonic gap between lows and mids. If you've done all this with both amps, everything else checks out good, and each of them still blows fuses, then you've gotten some amps that weren't properly refurbished. It does happen. Get your money back in that case.

When my RCAs are hooked up to my amp, my subs start hitting without any volume turned on


1. Check Grounding system (Player and Power Amp).
2. Ensure your RCA cable is OK
3. You might adjust volume or bass volume on power amp to maximum, just set all to 50% while you are tuning.

Ive got no power to the amp trough the rem wire unless i connect.


You need a bigger amp and make sure its a two channel. Four and five channel amps are for mids and highs. If you want real bass get a two channel. If you dont want to buy a bigger amp, Go get a capacitor. It acts like a battery charge storage for when your sub needs to hit those real low notes. It takes a lot of power. Also if you get a capacitor your altinater that charges your battery will not have to work so hard keeping your battery charged, Thus not wearing out your altinater and not having to replace it so soon because it will happen.

Another quick fix is turning your gain down. I turn my gain up half way, maybe a little past half way. You might not get the bass hitting as hard but at least it wont shut off on you.

This question really can't be answered accurately online for a few reasons.. we don't know if you have a ported or sealed box, we also don't know what kind of box you have, wether it's a 4th order, 6th order...blah blah blah. We also don't know what the box has been tuned to (if it's ported). unfortunately, you'll have to play around with it yourself or get someone to physically see your set up. But here are some tips to help you tune your set up.
1st set up the frequency( or crossover). this basically tells you sub the range it should run in. alot of people don't set up their crossovers properly and the sub is reproducing frequency's the mids are producing so some notes are far louder than they should, which makes for unbalanced audio. when you get that sorted out move onto the gain. (keep in mind, that if you've only installed a sub and have stock speakers or are running upgraded speakers off the head unit and not an amp the frequency is going to be harder to control since you can't control the other speakers.) next the gain, the gain is really just volume. Play a song with alot of bass and set the sub at a volume that pounds, but not to the point where your other speakers get drowned out and there you go, you should have a pretty good sounding setup. If this is the first time you're tuning it may take some time, but please do this with your car running, far to often i hear people killing their batteries as they don't realize that amps really do **** alot of power.
If you purchased the subs and box separately the box usually tells you what it's tuned to (if ported) and you can use that to guess where to set your frequency.

I plugged int he rca's but he the lowest sounding bass possibe


kicker subs arnt ment to hit the lowest bass, unless you go spend a **** load of money, im talking 3000 wat amp, ant some 15' or bigger subs. the most commen kickers are 12' subs, so im asuming you have 12' subs, if not, this (said lightly) should work. try turning the bass boost screw on the amp to the middle of its turning range. this will offer the greatest balance between high and low bass. if you want more low bass, turn it past half. if you want more high bass, turn it down. i have mine set to mid range, but i also recently purchased 2 18' kickers. with every new set of subs, you should spend at least 15 min tuning the amp to get the best performance. every sub is different. hope this helps, good luck.

Disconnect all speaker wires and signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.
