I need to go to parts store and see. it may not make any difference.

2 of mine look fine. one has a dull look to it..duller than the others ..might be a steel version. been a while ..I forgot the details on these different cases.

anyone know whats good to clean them up with? I was going to go to parts store and look for some chrome/steel cleaner.

I think I may upgrade it to o gauge. hadnt decided. only because I am not sure how long I will run these ...maybe long time..ha ha ...maybe a week. The only thing I hate about older amps of any brand is they are not near as efficient as the newer stuff out now. its hard to beat the efficiency of new...

I need to know if I need to run some 0 gauge or is the 4 gauge I have that is running into a distro going to be enough for them.

its 4 gauge then out (2) 4 gauge runs of about 2-3ft

the zx475ti is not in the car. just the other 2 . they looked fine. I am still going to see what I can find out. I may or may not end up keeping the titaniums depending on the outcome of the jl1000/1 sale.

I actually got my JL audio 1000/1 back from shop today and one of the tops on it was bubble and half off. peeled it off to reveal nice flat cap.

I will check these again tonight.

how do I remove the disk? cut it?

there is a red dot on one. I have no idea why

I put the cover on before I knew I had any responses .. I will open it back up later and check under the caps.

so how hard is it to get the board out the case so I can see underneath?

these look fine

I looked in my zx475Ti and it appears the tops of the 4 caps that are close to center of the board are swollen so I need to replace them. I am running the zx600ti and the 500.4Ti so that should allow me to try to change these caps myself. does the bottom of the amp case come off so that I dont have ...

I hope the zx475ti is more than that. that is less than the JL 300/4 I replaced with this 475ti

actually my memory is off . the zx475ti puts out more volts.

I would like to set them with a meter. Does anyone know the voltage output at 4ohms for these?

this doesnt look good at all...despite the sellers yo yo wasup player grammar lol! Yo yo wasup? Wtf? Anyways....this is over....the amp I got back goes into protection mode....but valeks can fix it to brand new dam near....so I guess live and learn. sorry if that offended you. its hard for me to ta...

holy smoke. I dont know Eric well but have talked to him. I am shocked the "substitute " amp would have been sent in place of the amp that was sold. if you think about it. the buyer got all his money back and the seller got "who knows what" and the seller may have a dead amp that...

fantastic. yes I mean the titanium amps ...all of these are the titanium. it would be great to not have to replace them right away. I will have enough to do one at a time. I will only need 2 of them. sweet news.

thanks Eric

I am fairly sure about this but thought I should double check. trying to get my hands on a zx600, zx475 and a 500.4 .

how hard is it to replace them? anything else needed while amp is apart?

I got one from guy who sold me the parts I picked up off ebay. I am not a tech so I havnt even looked at the pdf yet.

I got one that needs a little attention. its a receiver/amp MRX130 but it was free so I am trying to change out a few things and use it if I can.

I know this is a PG forum but I have really wanted some old SS ref amps again cause the wiring is all on the side (like the JL) .......

arrg. why do I look on these forums.

JL 300/4 bridged is 34.6 volts @ 4ohms so that would be close. the JL should do that a little easier due to power supply or am I thinking of it wrong?

this is tough. I will have to find a zx450 again..I have owned 2 or 3 of them already.

pillow I am going to email you again.

Good info. I need to see how much the JL amps put out. I have a number in my head but can't recall if it was the 4 or the mono.

I think I am going to sell my JL 300/4 and 500/1 and pick up pillows zx500. what were the real numbers on these? I really was looking for a pair of Ref soundstreams but he already capped the zx

the company is no longer USA as evident by the above link and no longer making amps.. but it was a USA made in Florida at one time.. I have my hands on a new in box XP2100 but not sure I am going to go through with it. I dont need it and it was a impulse buy because its pretty rare...its new and its...

not the rms 600 watts or whatever...I mean like safely max steady rms of good clean power....

I know its rated 600rms 1200 max or something like that...

these things were hand made in Florida at one time...once upon a time

anyone here hear one before?


I have one but not sure if its what I wanted...impulse buy...xp2100

its new with box...havnt decided if I want to keep it or not ....like I said impulse..

never hear much about them
