Sold FS: Kicker ZR series amp circuit boards

[Ge0 10+ year member]

Let me start by saying these circuit boards are NON FUNCTIONAL!!!

With that said...

For one reason or another I have a small stock of non-functional Kicker ZR, XS, and ZX series amplifier printed circuit board assemblies. I repaired many of them, threw them in heat sinks, and sold them to friends as refurbs. To make a long story short, I got busy in life and dropped this activity. They have been sitting in my basement for a few years. I've come to the realization that I will never do anything with these again now that I have a babies in the house. No time!!!

If you ever wanted to screw around with amplifiers at the board level this is your chance. In most cases these are relatively easy to fix. I will offer whatever advice I can to help you get them up and running. Mind you, if you do get them running and you want to use them, you'll need to buy a heat sink or fabricate one yourself (which can be fun).

Here is my price list.

ZR1000 - $40

XS100 - $40

ZR600 - $35

XS50 - $35

ZR360 - $25

ZX460 - $20

ZR240 - $20

ZR120 - $15

Willing to give discounts for package deals.

I am newer here but have been around various forums for over 10 years. References available upon request. Or, search my user name on Elite caraudio, Sound Domain, or DIY mobile audio.

Pictured are ZR1000, ZR240, and ZR600 PCBs. I can take others on request.

god...i used love zr's...

in my little group we had a LOT

4 600's, 5 120's, 4 zx460's, too many 240's, 1 360 (girlfriend still runs it), and 1 1000...haha, great amps back in the day

Still are. You can find them pretty cheap now too.

Hello GE0/

I love those Old School Kicker ZR/ZX Amps/.I have around 11 or 12 of them.

I have 4/of the Polished Heatsinks...N.I.B's and some others I bought on E/Bay.

I have 4~ZR/1000's.One has a bad board/ .I have a ZR/1000 & a ZR/600 in my '98/Saturn SC2.Sound great to me.

I wish I was Electronically good...as I'd buy a couple of them to repair.

I would'nt know where to begin.All the Best w/your Sale.

Kind Regards/

Raymond/

Thanks.

I wish I had more time on my hands these days or I'd offer to fix them for you. But, family life drains too much of my time to think that I could turn these around for you in ANY amount of reasonable time.

I have a XS100 sending some weird voltage out to speakers...as soon as you hook it up it blows the speaker...any idea if I bought that XS100 board what part might cause that...I could swap...all the parts look good on my board I can't find anything that looks burnt

Sounds like a problem in the voltage gain stage or possibly a blown output transistor shorting one of the power rails to the amps output.

Question for you. Why buy another board from me and fix IT when you could fix the one you already have? I don't intend on loosing out on a sale, but I couldn't honestly take your money and send you a non-functional board that would potentially be just as hard to fix as the one you have.

Do you own a digital multimeter?

I brought it to one repair shop...he couldn't fix it...I'm sure he checked a lot of the common problems....

These are very nice and simple amps. Easy to fix. Too bad these are just boards without heatsinks //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

I need a good reasonble repair place to send my XS100 too...

Where is your sense of adventure? Crafting your own chassis and heat sink is half the fun. About $80 in aluminum extrusions and sheet stock. I used to have pictures of some of the amps I've done (including a monsterous 6 channel beast made from three ZR1000's). However, they were stored on a hard drive that crashed about a year ago //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif.

Let me see if I can free some time up during the holidays. I MAY be able to repair one and sell it to you for a modest price.

BTW: Have you contacted Stillwater Designs to see what they want to repair it?

Id probally be more interested in a working ZR1000 board if it is 2 ohm rated for full power...I remember on one of the Kicker specs that they lost power at 2 ohms...went from 1000 to 700....I'd like something that did full power at 2 ohms (1200-1500)....Can that be done?

That gets a little tricky. The amp has a current sensing circuit that steps down the secondary side power supply rail voltages when current demand becomes too high. I've heard of people defeating this circuit before but the amps typically don't last long thereafter if continually pushed too hard. I would have to do a little digging to see how this was done and if I would personally recommend it.

I do know a considerable amount of capacitance would need to be added to the secondary side voltage rails to keep the rails stable. The FETS on the power supplies primary side would need to be upgraded. So would the rectifier diodes on the secondary (if possible, the existing rectifiers are already about as big as you'll get).

I don't want to create something that will not be relaible.
