Just built a system composed of Polk monitor 60s, Polk CS2 center,Bose 301s(surround) on a Denon 591 AVR and now i am looking for a decent powered sub. Something in the low $300s. I have'nt heard very many so i would love some input. THANK YOU!
On sonicelctronix.com you can buy a deck and they will throw in free install equipment (kit, harness, antenna adapt. I also had polk dbs for a while.. loved em. ran them off my deck for about a month then put an amp on em.
The 4200 was around $1200 new in 1995 from memory, rated at 50x4 @ 12v but can run active and complete systems off them no worries.
