Need advice, please

[reunited]

Hi-

I just wrote a lengthy post that disappeared into the ether.

Now, for the shorter version:

I have a 2012 touring, sport and nav coupe.

I have a Rockford Fosgate Punch 300-2 amp with Audio Control LC6I converter powering Rockford Fosgate T2 component speakers up front.

Of course, now the bass stinks. What is the best way to upgrade the subs. Go with RF Punch 8" sub woofers (two I assume) or something else. Will the existing Bose "enclosure" handle these or any other w/o buzzing, vibrating, etc.? Do I swap out the RF amp for a more powerful RF multi-channel amp or do I get a RF PBR monoblock?

I am 62 years old and prefer accuracy and correct bass levels as opposed to something to something which would loosen my fillings.

(If important to know, I also had the hatch, doors, and wheel wells dynomatted.)

Suggestions appreciated.

Best regards-
Bill
