Suggestions for Sub-woofer + Mono-Amplifier for Hyundai i20

[rupinder.jit]

hi, i have i20 crdi1.4 magna, here the details of my current setup:
oem hu,
front comp.: focal polyglass 165 vb,
rear: focal polyglass 690 cvx on rear wooden plank,
above powered by focal solid 4 amplifier.

Now I need to add sub-woofer and mono-amplifer. Am planning for Infinity Reference 1260W sub woofer and kenwood kac-8105D mono amp.

Guru's could please suggest me if the sub and mono amp planning to install will work fine with existing set-up.

my budget is 20K max ONLY.

You can go for the solid 1 and the focal access sub in a ported enclosure rupinder,the infinity refrence is a great sub though,the focal has better SQ.
