Impedance and ohms?

Question

last question. i learned that you can wire subs so that the ohms dont have to be the same. but im wondering if a set of 2 ohms subs or 4 ohms would work better with my 2 ohms amplifier. i understand that the lower you go the harder it has to work, so please tell me which one would be better setup for me

thanks a ton for who answers!!!!

Answer 1

yes, you should buy the speakers that will have twice higher impedance than the lowest impedance load written in the amplyfier specifications when connected together. it will give you safety and stability. you will loose around 3db of SPL, and it is not enaugh and not so painfull.

Answer 2

it really depends on how many woofers? single or dual voice coil? and what amp stability is....2 ohm stable stereo? 2 ohm stable mono? is the amp bridgeable?

Answer 3

It depends on (1) how many woofers (2) are they single or dual voice coil woofers (3) is the amp mono or stereo. You will get the most out of your amp with woofers with a final impedance of 2 ohms but yes it will work harder and run hotter. IF you are going to run two woofers on two separate channels you want a final impedance of 2 ohms per channel, for this you can use either single voice coil  2 ohm woofers or dual voice coil 4 ohm woofers(with the dual voice coils wired in parallel for a final impedance of 2 ohms). I posted a link to Rockford Fosgates woofer wiring wizard tool. It will help you figure out different setups. Wiring option 1 on the link below shows how to wire a dvc 4 ohm woofer in parallel for 2 ohms.
