what kind of subs? you also need to know the impedance (ohms) of the woofers. you don't want to go below 2 ohms on the alpine. that would be 2 x 4ohm woofers wired parallel.
The subs are both Alpine Type R 12" with 4ohms. Is it safe ? Do I need to get anothe amp with the same wattage?
yeh that would be fine.
Is it safe to run ( 2) 12" subwoofer powered by Alpine MRD-M301 (older Model) that puts out 350wx1 at 4ohms? I would wire the 2 subs into the speaker output of the amp. Many thanks...Dino
