Sold FS:Digital Designs Z1 w/Minor Problem

[hotsizzle56 10+ year member]

I'm thinking of selling my Z1 and upgrading to a newer model DD amp. This just came back from repairs (Amp Repair Center Ohio) but unfortunately they didn't fix one problem. When I turn the car on and off, theres a LOUD thump that comes from the subs. I tried everything possible to fix it but I'm pretty sure its a defect in the amp itself. I was told its 2 capacitors in the amp that needs to be upgraded. I'll take pics as soon as I can cause I know people will dump on my post about my post count and whatnot. I'll also get the pics of the caps that need to be replaced. As for the price, I haven't thought of one yet so if you have a price in mind, hit me up. Btw, I'm located in Hawaii so shipping will kind of hurt but I'm willing to work on the price. I'll also take a pic of the reciept for the repairs. I'll also send it to the buyer (if I find one).

you have to state a price. its forum rules, just letting you know.

How's about $600 plus shipping? I'm losing out since the amp cost me $850 shipped then $300 to repair not including shipping to and from the repair center. If not sold soon, I'm gonna just replace the caps and keep it.

itll take you longer to pull the amp and open it then to fix it, btw the caps are like a buck a piece.... atmost...........

You seem to know this problem already. Can I use any 100uF/25v Caps to replace the stock ones? TIA.

 

[yunvme666 10+ year member]

or try an external delay for off , made that for like 5 bucks too....lmk........ ill help ya , if i can.....

i got a transisitor, a diode and a cap on my remote line for turn off, i did external cause iwasnt sure if its the head unit or amp i will be trying a diff head this week when it arrives, and as far as 100uf i usd a 220uf 25v or somethin, 220uf=2.2 second off delay

 

[hotsizzle56 10+ year member]

Yah I had a relay installed to delay the turnoff but no luck.

 

[hotsizzle56 10+ year member]

Thanx for all the help. Is it safe to use those caps you used? And can I find them at Radioshack or online?

mae the external one first, go to radio shack get a tip42g(transisitor), a cap your choice of delay time, 100=1 sec,200=2sec, u get it right?, and then a diode i used 1n4002, get 3 fuse holders , 2 buss 1.25x.25 with 1 amp fuses, and a regular atc i think fuse holder witha 30 amp fuse......

sit the transistor down 3 prongs toward you, exposed meter tab side down black side up,there shold be a b (left),c(center),and e(right) on it near the terminals not allive seen had it tho.... take the + lead off the cap and twist the diode , with the stripe side towards transisitor together , solder it, also solder a extension for ground off the - side of cap also. next take the peice ya soldered, the + side of cap, solder that to the first pin in the transisitor. from the other side of the diode , solder a buss fuse holder in for the 1 amp fuse. no the center pin on the transisitor gets a 1 amp fuse also, use the other buss fuse holder. solder that on. now from the remaining lead off the transisistor, solder it to the 86 pin in 5 wire relay, youll be using all but pin 87a. now from the relay 30 goes out to the amp, 85 gets ground, 87 gets a 30 amp fuse . and then the fuse holder inline with the diode goes to the remote from cd player..... hope it helps i couldnt find the diagram or it would be a lil easier.... saves 30 bucks or more tho buyin a pop stopper......

when im done i tend to epoxy it together seeing i dont use bread boards....

 

[yunvme666 10+ year member]

sure i find it after i write that,lol....oh well heres a link to a pic of how to wire it, i cross'ed the transistor number to the one i gave ya besides that all other part numbers are the same..... voltage number is just max voltage it can take and were only using 12-14v , or atleast me...
