i have an alpine 357 amp, i am wondering if i should get a jl12w3 or a polkmomo 12". i dont know which is better for wiring to the amp. if i get a dvc sub, what is the best way to wire it to the mono channel
If you excellent quality at a good price get the JL.
Alpine specs the amp sub channel at 100W @ 4 ohms. Not sure if the 5th channel can handle a 2 ohm load or not. If it can only do a 4 ohm load as they rate the power, you'll need a dual 2 ohm series wired to get your 4 ohms.
The amp may be able to handle 3 ohms on the seperate channel and in that case you would need the dual 6 ohm model parallel wired.
I'm sure Zane could tell you about Alpine's abilities. Give him a buzz.
