Re: good system?
it would be fine since it doesnt take much to get those subs moving but you can run it at 2 ohms on the 5 channel ppi amp tenacious listed and you'll have 440 rms to play with. Get the D2s and wire it in series. that amp should have more then enough power to cover future speaker upgrades if you ever want any. hell maybe in the future you might get a dedicated sub amp and use that additional sub channel on the ppi to power some midbass speakers too.
