Those RE subs are awesome ! Actually all those subs you posted are great quality !
As for amps, I'd go with JL Audio ! They are awesome build quality and sound superior to most other brands !
I myself bought something else though for now.....
In my yellow crx ,I am running a Kicker 10" L7 in a huge ported box to spec, with a fosgate BD 1000 Powering it ...People think I have 2 twelve inch subs.....lol
For highs I have 5 1/4 Alpine's, with an Alpine mrv-f340 2 channel amp running them... I am using the latest Alpine deck.
I dont even turn it up 1/4 of the way for fear of shattering my crx's rear hatch glass...
can you say overkill ?
Right now I am looking now to get something simple for my red crx.
I need a 4 channel Zapco or JL audio amp... maybe JL 300/4
or Zapco AG360.
