hello experts ,

I have an altima 2005 and I have already replaced the four OEM speakers with Alpine's R-Type speakers

in the front : SPR-17LS

in the back : SPR-69LP

--------------------------------------------------------------------------------------

now im planning to intall a 12'' R-type subwoofer with

this amplifier : MRD-M605

to acheive the best configuration without affecting the car electrcity or the car head unit or draining the battery or over heating the amplifier

should I go with this subwoofer

SWR-1242D(4Ù + 4Ù)

SWR-1222D (2Ù + 2Ù)

they are the same in everything except the ohms

and thanks very very much who would give me a little help

Your amplifier is capable of a 2-ohm load, so use the DVC 4-ohm speaker, both VCs in parallel.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
