Have you searched for the RRP on it? I haven't yet, but will.

But besides that why do you want a 2 channel amp to run 2 subs for? Unless they are DVC 4 ohm subs, even still, it's not reccomended....

The amp is a good price, but what are the sub model numbers?

Its just a cheap one i saw, dose it matter that much if its only 2 channel?

Im not sure mate, there at a mates place im buying them off. They are kinda old but they still go hard as.

[acarmody]

Depends on your definition of hard as. But I ask because the impedance will determine how much power the amp can feed to these subs, if there are Pioneers base model subs than they will be 4-ohm each, then the most power you can expect is 210wrms each sub.

[dumpedvs]

ohk, 210rms is still pretty good tho.

[acarmody]

Yeah mate for $220 its still pretty good.

[HCVP]

Well it depends on your expectations. 210 rms going into a sub is enough to get it moving, and depending on the sub it might be close to it's rated input.

But mate you will be flogging the shit out of the amp. That amp is designed to run a pair of front speakers, not 2 subs, it will do it, but yeah i wouldn't....

[dumpedvs]

I see...., Ill post up the amp so you can have a look:

Cheers.

[HCVP]

Why would you buy it from California? Prices in Aus aren't that bad if your desperate for a cheap amp...

[acarmody]

Just pay a little more and do it properly.

Shopping Secure - Car Audio Specialists - Option Audio OAX502

[HCVP]

Agreed.

I know the dollar is high and there might be some bargains to be had, but i don't see buying a $200 amp from an international Ebayer as being one of them...

Considering you only have a small amount of money to spend, i'd be inclined to minimise the amount of risks when buying.

OA amps are good value for money aswell.

[dumpedvs]

Thanks for the info, but a monoblock can only run one sub yeh?
To be honest ive never heard od option audio.. are they good?

[HCVP]

Option Audio are pretty good for the money, and definately on of the better choices when on a budget.

You can run as many subs as you want off a mono block, provided you match the impednce levels. Mono blocks are designed to put out more power at a lower impedance which is why they are more suited to subwoofer applications. If you look at the specs of the amps, you will see the power output varies at different impedance levels. You will see it as "ohm" if your not sure.

I'm not familiar with your sub, but i think Acarmody had a guess above saying the they are a single voice coil 4 ohm. So any amp that produces good power at 2 ohm is what you will be after. (best just post the model numbers though of the subs to be %100 sure)

Depending on the voice coil arrangement of the subs, will determine how they can be wired and what impedance load they will put to the amp.

Basically wiring in parralel will have the load, wiring in series will double it.

If you jump on google and search a few key words like parralel and series wiring, and subwoofers, you will see a heap of results. I won't link you to any specific one as there are probably better one's worth reading.

[dumpedvs]

Thanks alot for the info HCVP.

Ill get the sub model numbers asap.

[dumpedvs]

I know that they are pioneer 12' 600w subs. About 5 years old.
Not sure about the rms

[HCVP]

RMS dosen't really matter we can pretty much guess that based on the peak output of 600.

Whats important is the voice coil arrangement. There should be a model number on the magnet?

[dumpedvs]

EDIT: I just remembered they are clarion.. My bad.
They are at a mates place at the moment thats why I cant check now.
I know they say Clarion (model number) competition series 600w

They look the same as this but are 12 inch

http://cgi.ebay.com.au/CLARION-15-PA...item3f02da3797

[acarmody]

Is this them? Clarion Singapore | PA12-S

They don't even give you an RMS power rating, speaks volumes about the quality.

[dumpedvs]

Yehim pretty sure thats them. It has the rms on the magnet i believe

[HCVP]

Ok so SVC 4ohm, so a good 2ohm amp is what you should be chasing such as the ones mentioned above..

[dumpedvs]

Okay ta,
So a good 1/2 channel amp ?
