I bought them originally just to replace the stock crap but after reinstalling all my equipment wandering if they are the weak link. I currently have them hooked up to a hifonics 600w forgot the actual part #.. So 6.5s in the doors and polk db's in the a-PILLER..Since pg rsd are so cheap and popular I was gonna pick those up but is it worth it? If so I was gonna keep the polks in the a-pillar and put the rsd tweets in the kick panels. Its a 350z doors arent deadened as of now but will in the near future..Oh yeah and theres 2 jl10w6 in the back wired at 1 ohm brutus 1606d
