Chester- thank you for the advice! What amp wattage would you suggest? And what setup?
The speakers came in today and they look lovely. I wish I still had the other Focals to do a side-by-side.
I purchased the component Focal system (165KRC) and what is essential the same product with integrated tweeters (165KR).
Pics to follow....
The setup you have choose can do the job, the size of the speaker is good, the amp i recommend you 4X 80 W min to 120W, if you want big bass got to US brand Rocksford / Fosgate , Infinity , Pyle , Crunch if you want more medium & tweeter But with lower bass) go for Piooner, Kenwood, Alpine.
Before choose you amp's be sure your source have 4 low level source out (not all have that)
As you will do the job, if you don't want to have the engine in your speaker use strong ground to the radio and the amp's and avoid to let the amp's to any ECU or electronic module of the Car.
