Home Built System Upgrade suggestions. (if I need to post This else Where Please tell me Where)

[Mada81]

I am visually impaired and can not drive I do ride an electric assist Bike to get around. here is my reason for posting here. a friend of mine gave me his old Subwoofer box, I ended up putting a little system in it. 

At the moment I have 

The stereo is a Dual DCPA81W

Speakers are NVX NSP65Kit 6.5" speakers and tweeters

AMP is a LeigesAudio TG-500.1D

Subwoofer is a Kicker CWCS124 CompC 12" 4-OHM

Since this box was a Dual 12" sub I got a Kicker 12" Passive Radiator to put in the second mount. which made it easy to take it out to make changes to my amp, I also have some speaker liners to protect the mids from the sub.  My friend who has a system in his Tahoe helped me choose the components. I have a 12V 30A AC to DC inverter to power everything including the lights. it dips down to around 11.2v when the sub hit and the LED light strip is on. I also use this system for movies nights on the weekends with my family where we use it for the audio and have a projector set up in my carport.

Here is my question. I am thinking of getting myself a better-ported box and a amp to power my Mids and Highs. If you have any Suggestions would be helpful

 

Thanks
