Talk to VPElectricity (Ken) at MusicarNorthwest.
He can fix you right up.
GREAT products, GREAT service, GREAT sound, all connectors included, all devices pre-set (except for amplifier gain), all plug-&-play.
I got the Morel Dotech door speakers/tweeters with Jehnert 8" underseat woofers (subs?). The sound is fantastic, and it's now plenty loud enough to listen enjoyably even with 4 windows down & the roof open.
Remember: nobody ever looks back and thinks "gee, I wish I bought a system that wasn't this good"...
