I think the Xtant is made in US. That amp should also come with a feature that'll let you use rca for balanced input. Helps to get rid of ground loop problem.
hey budy this is the specifications for xtant amp Features: Fully regulated, PWM power supply. Doubling of power from 4 to 2 Ohm loads. Hand-matched, complementary MOSFETS for better performance and sound quality. Fully discrete power amp. Independent amplifier gain adjustment. Over-current and thermal protection circuitry. Selectable Balanced line inputs. Unbalanced input sensitivity (100 mV to 8 V RMS) adjustable in 10 dB steps. Balanced Input sensitivity (100 mV to 17 V RMS) adjustable in 10 dB steps. Four amplifier accessory ports which accept our plug-in modules. Specifications:

the xtant amp doesnt have crossovers, not sure if i need them ? what you do think
I've tested and used the Xtant, it is a great sounding amp. You don't need xovers for components. Unless your HU and the amps have solid ground, you might get groundloop problem. The Xtant will get rid of it using rca for balanced signal input.
Sinx, were you the one bidding on the Xtant 604x amp?? I was going to buy that for $150. Well I think it's you, so I am not bidding and letting it expire. If that's you, you're getting a super deal. Man things I do for memembers on here. Anyone else, and I would've snatched that amp up.
hey bro some one outbid me damn i should have put higher amount on that amp. well what should i get now ?? i thought i was gona win this one and only had to worry about getting one amp for the woofers. Now i need 2 , one for speakers and one for the subs.
Are your subs 4ohms DVC or 2ohms DVC? If your subs re 4ohms DVC, then Orion 2500D is your only choice. If they're 2ohms DVC, then Kicker is your better choice. All depends on your subs.
subs are 2ohms. so kicker 2500d is my only choice?
also for my speakers, i didnt win Xtant 604x on ebay but some one is selling ORION 8004 4 Channel Amplifier. should i get this instead? is this as good as 604x ? or i should wait for another xtant 604x amp?
If your subs are 2ohms DVC(very important), not SVC, then Kicker is your better choice. Look at the spec, 2500w @ 2ohms. I wouldn't say Orion 8004.4 is a better amp than 604x, but it's not a bad amp either. If you get a good deal, then go for it. 604x was designed and built in US.
Sinx, if your subs were 4ohms DVC, then those 2 would give you 1ohm total resistance. Therefore, with Orion, you'd get 2500w x 1 @ 1ohm. Kicker is not 1ohm stable, so it won't work unless your subs are 2ohms DVC to start with.
thankx got it now so 4 ohm subs can also be used as 1 ohm if your amp can handle it. about the 4 channel amp. i got ford expedition and i think just 2 front speakers wont be enough for 2nd and 3rd seat. so i was thinking of hooking 4 componenets 2 front and 2 back.
hey isaac ,can you plz help me out with this. if i buy orion 2500d amp which gives 1700 rms at 2ohms and run 2 10" re sx which are total of 2000 rms at 2ohm , will they run ok and sound good. Each sub will get like 850 rms. i was thinking like if i get a kicker 2500 amp and later on i change the subs and get something that are 4 ohm then the kicker amp wont be as good as orion cuz orion can give 2500 at 1 ohm.
The WCCD5000 is pretty much the same as 2500D amp. The difference I see is, WCC is CEA rated. If you're into the new rating stuff, then WCC would be your better choice, if not 2500D is still good.
damn i should have put higher amount on that amp. 
havent bid on it yet, still thinking if i should wait for another 604x or just buy this one.
