Since I've upgraded my HU, I really wanted to take advantage of increasing my SQ and all around system performance.

Here is my potential setup:
JL Audio XR650-CSi
JL Audio TR690-TXi
JL Audio Slash 450/4

A mono amp and sub will be added soon afterwards.

What do you guys think?

My car is listed in my sig.

 

I know I wil surprise everyone with these comments:

1) The F speaks look pretty good. I don't know if they are a good deal but they're pretty good gear.

2) Do you REALLY need rear fill? Sq and rear fill are not synonymous... A lot of the "rationale" for R fill is R seat passengers... you drive a CL, not a 4-door car, not applicable, I suspect. May I suggest getting even better F speaks and leaving the R fill off the list? I've heard CLs set up like this... a friend did an Alpine HU and video system, Morel mids, Scan_speak tweeters, and a long-throw 10"... sounded great.

3) Why have more power going to the R fill? Or are you going to run the 150W channels to the Front? I think you could run this fine with a 300/4 if you are running the 6x9s as R fill... no reason to give them more power. Or use a 450/4 and run F separates and a sub...

 

I was thinking the same about the amp. I'll probably go with the 300/4.

As for the rears, I actually prefer the mids and highs coming from the rear too. But maybe I will see. Maybe woofers might be a possibility for the 6x9. Dunno yet.

I'm leaving my options open. Thanks for the suggestions.
