Car Stereos: Amp and subwoofer wiring - 4 Ohm DVC sub or 2Ohm DVC sub, impedance capability, subwoofer wiring

Question

Image Hi,

I have bought an amplifier whose specs are as below:
•(RMS)Continuous output power: 1 x 360 W (2 Ohm)
                            : 1 x 250 W (4 Ohms)
•Load impedance capability (2 — 4 Ohms)

Could you please advise me from the below mentioned subwoofers which would perform efficiently at the optimum with a better SQ considering the subwoofers ( 4Ohm DVC and 2 Ohm DVC)have the same output of RMS POWER 500W

2 Ohm DVC sub connected in series as per figure 1 for a 4 Ohm load on the amplifier
or
4 Ohm DVC sub connected in parallel as per figure 2 for a 2 Ohm load on the amplifier


Any help regarding the query  will be much appreciated. Thanks in advance

Michael

Answer
Michael,  Well thought out question.  The higher the ohm load, as in the figure one, will have the best sound quality.  Your high-end studio monitors that are used by professionals are always 8 ohms or higher.  The lower the ohms load, the more power is translated into audible sound.  Unfortunately, the lower ohm usage drops the sound quality.  If you want power, use figure two.  If you want better sound, use figure one.  Hope this helps, Scott
