here i go again. i bought a Infinity Reference 610a mono amp and a pair of infinity kappa perfect subs which are DVC at 4ohm per coil. the RMS out of the amp is about 620 and the subs handle 350 rms. which will be the best way to wire up my system?
thankx

small problem here my friend. your subs can either be wired to 1 ohm or 4 ohms...your amplifier can not handle a 1ohm laod so that is out and at 4ohm your amp only puts out around 300watts at 4ohms.... to properly run this you would need 2ohm DVC subs not the 4ohm DVC's you have. you would need a 1ohm stable mono amp or a 2 channel amp.
sorry. but there is not a way to run this amp and these subs and not cause too little power to the subs or cuase damage to the amp in the long run.
we can show you the best way to wire it but it well only get 300watts.

ok. here is what i'm thinking, correct me if i'm wrong. lets wire each of the subs VC in series so that there is a 4ohms on each sub. got that? i now got two subs at 4ohms each ok. what if then i wire in paralel? wont the amp the a 2ohm load?

With 4+4 DVC you have 2 options:
a. 2 ohm load with both coils in parallel
b. 8 ohm load with both coils in series
Now, if you have a pair of them, the best you can do is 1 or 4 ohms, depending on how you configure them. If this amp were 1 ohm stable, you'd be fine. Might try contacting Infinity and ask if this amp "will" work with a 1 ohm load and remain stable. They may tell you it will void your warrantee if wired to a 1 ohm load.
Can you exchange this amp for a 1 ohm stable amp?

i would just probaly buy another of the same amp or return the subs for svc

Hold on guys. I believe this amp is 1 ohm stable. My friend is getting this exact setup. I emailed infinity about this amp and i believe it is 1ohm stable just like the jbl amps since they're made from the same company or whatever. Let me just double check to make sure im right

I already eraesed the email but i did look at there site. From looking at it im pretty sure its down to 1 ohm stable but you dont gain any power. Since it didnt show the stable rating and just showed the power at 2 ohms, it made me question my wiring options so that made me email them in the first place because i thought it would be a problem in wiring the subs up. But im pretty sure it 1 ohm stable so before you do anything just give infinity an email asking if the amp is 1 ohm stable. It doesnt hurt to try and they get back to you in about 24hours.

if it is one ohm stable then it well work howvere i looked threw the manual online and nothing is mentioned about 1ohm stable... dont know why they would make it one ohm stable and not list it thats a very big feature and would make a big differnce in who bought the amp.
if it is then wiring these subs to one ohm well work great, if its not one ohm stable then your going to have problems with this setup.

Am beginning to wonder if JBL had too many returns (FIELD FAILURES) due to specing the BP-xxx.1 series at 1 & 2 ohm loads. They have changed their marketing approach on the newer series to say... "2 ohms stable only". That was even noted on later versions of the BP-xxx.1 amp series. This is not an absolute statement. But, more like an observation have noted on later models of that series amp.
If we need a 1 ohm stable amp, better to make sure it's clear the amp can handle it. Most HC (High Current) amps can do that or lower. But, the current draw on such amps, are very high compared to Class D or T amps of similar wattage ratings.
