Yeah the corroded pots were an issue before, but the tip to turn them a few times to the left and right worked great. when troubleshooting my zx500 isue, i did notice that my zx450 fan has become noisy. Didn't notice it before cos the amps are in the trunk. Do you think a fan replacement is the only...

Hi Guys I know this is an old thread, but i wanted to post a reply so that it could possibly help a fellow user with the same dilemma in the future. The problem was actually the remote turn on wire not making proper contact. That's why it worked intermittantly. Turns out the remote screw hole's thre...

A small update... The sub has been playing normally for the last 2 days. The fan on the ZX500 still didnt spin from sturtup but started when the amp warmed up. The temperature on both amps feels the same, and no protection kicked in yet. listened to the system for about 30 mins earlier and when i ch...

Thanks, so i'll definitely need to book it in for a repair.

I was hoping there were some home trouble shooting tips that could help, like when my gain pots were dirty and just needed to be loosened up.

lol, ok maybe that was just wishful thinking. but i need to get it repaired soon. i love this amp.

Hi Guys I need some advice on what the possible problem with my ZX500 could be. It intermittantly loses output to the sub, and the fan doesnt spin. (The fan just flicks continuously, but doesnt spin.) The amp doesnt go into protection. The green light stays on. I turned on the HU and got a loud humm...

Im currently running the only 2 channels of the 450 to my comps at 2ohm, and have 2 free channels.
The passive crossover in the Focal set works well for me.

If i can get the benefits you explained, i'd really like to get a line driver. And i def would like to be able to control my sub seperately.

Thanks for the quick reply.
Yeah the current setup sounds really good, but if there's any way i can improve it with just what i have, its totally worth a try.
I dont see myself changing the equipment anytime soon so the line driver will be a quick add-on.

Hi guys I heard that the x200.4 needs a line driver to boost its input voltage in order to get the most out of it. I didnt get all the facts, but started wondering if my ZX450 and ZX500 could also benefit from one? I run signal from my Alpine 117 to the 2 amps. I believe the HU is 4v preout. Current...

I had the same issue a few months back on my zx450, and turning it back and forth worked perfectly!
(although, i did it about 20 times per pot, lol)

I did this yesterday and i believe it's 95% better, if that's possible. I tested using my reference cd and it slightly still pulls the stage to the right. so i think we on the money with this troublehooting step. The scratchy distortion at 3/4 volume was not audible, so i'm happy about that too cos ...

I appreciate any and all advice. How awesome is it to have a forum dedicated to your brand of gear, and have knowledeable members give advice based on proper experience of your product, and not random thumbsucks, just to post something. Thank you all! PG - great brand - Awesome sound - great support...

i'll try this tomorrow morning, or the next time the problem arises.

Hi Im using my 2 front channels to power my focal K2P comps passively. rears not in use. Was installed a month ago and sounds fantastic, that is til a few days ago when i was driving and noticed an imbalance in the sound. The right side was louder. Stage sounded like it shifted to the right. When i ...

Hi guys, i have one last quick question. What will the difference between 2200uF and 5600uF caps be?
The eletronics store only has stock of the 2200, but can order the others.

Thanks

Is it the 4 caps behind the power input that needs replacing?
Under the right side plexi?

I found a nice tutorial and will give it a go myself since it looks easy enough.
When i remove the cover, should i remove the fan from the cover, or does the fan unplug easily from the board?

Not to hi-jack this thread, but whats the deal with re-capping the old school PG amps?
do all amps need this kind of maintenance as i've only heard about it on this forum about these amps?

BUMP

Thanks for the input so far guys. I'd still appreciate if peeps can post pics or even links to threads that they may have come across.

Cheers

I'm with you there bro, but i got the sub for cheap and it's not for pounding, just some bottom end to compliment my fronts.
I've been driving with the stock system playing off my Alpine 117 for the last 6 months now and i'm desperate for an upgrade.I do plan on changing out the sub later in the year.

In all the posts ive read, the users of these amps regard them highly.
I'll be running Focal K2P speakers passively at first off my zx450 and a JL12W3 off the 500.
Next week can't come soon enough!!!

Yup, that was me asking

The build looks really nice and neat. How do you like the SQ of these amps?

That's definitely what im trying to avoid. That's why the idea of each amp on either side of the trunk, with the MDF sub enclosure against the back seat, and sub firing towards the tailgate appeals to me. Then if i need to load or get to my spare wheel i can just unplug the box and remove in a few m...

Yeah that would have been awesome to see. i thought of an amp on either side of the trunk, so that it could still be usable if i remove the sub enclosure. Another option was to mount each under the front seats. Since these amps are so rare here in South Africa, i really wanted to show them off. I ha...

Hi guys Ok so for my first post i'd like to ask if the peeps with ZX amps can post some pics of their install. I'll be installing my ZX450 and 500 next week, and i'm looking for some mounting ideas. From what i've read, these amps are pretty good. I haven't heard them yet, but very excited to. I bou...
