how if put 2 sub to pareller or series to 2ohm and 8ohm?

what is the problem if put pareller to 2 ohm?

and what problem if put serise to 8ohm?

i have 2 12' 350 watt sub
need some help thankyou alot,

read that above...

what kind of sub you have? single voice coil or dual voice coil??
what's the impedance??

Are your subs SVC or DVC?

What is the ohm rating for each sub?

Running at 2ohms or 8 ohms is not a problem, however:

1. Make sure your amp can run at 2 ohm stable
2. For 8 ohms, the sound output will be very soft, u have to set the gain on the amp to be very high to get a `louder' output.

thanks for imformations...

mine is 2 audio quate 12" 800 watt max 4 ohm .
however will it spoil the woofer at 8ohm? series conections? i try b4 with my sub amp, don feel soft, still very powerfull, but b4 comfrim the risk i not dare to push 2 woofer with 8 ohm series connection,

but i know if run with 2ohm load the amp will hoter and got risk of killing the amp, so i only aim for 8ohm series connections

however will it give problem to spoil the sub woofer with 8 ohm load?

thankyou

Ok first off: what kind of amp are u using? What is the RMS rating of the amp?
You should try to match the RMS rating to the RMS rating of the subs as well.

Actually, if u run both the subs at 2 ohm load to the amp, it's not a problem just as long as the amp is able to run at 2 ohm stable. However, you have to be careful with the In/volume level on the amp (if it is powerful) so that it's doesn't `kill' your subs ie. burn the voice coils.

As for 8 ohm loads when wired in series, it is a `safer' mode for your subs as there is more impedance from the power of the amp to the subs. However also, the `amp' has to work `harder', ie. giving out more power to overcome the 8 ohm load on the subs; plus also to be loud enuff to reach your desired volume level.

As long as you pandai `jaga' the gain level on your amp, you should be fine, whether using 2 ohms load or even 8 ohms load.

Hope this helps.
