Checking Build before I Buy

Hey! I’ve currently got a 2ohm American Bass Godzilla sub and am finally trying to get it powered fully and correctly lol. In an effort to do it right I’m just gonna double check my stuff here and see if anybody would see anything they’d personally do different or replace with a different part!

Currently I’m planning on

The big 3 and a 300a alt
Also a XS Power D2400 3500 AGM battery

Taramps MD 5000.1 Car Audio Amplifier (this is what I’m most unsure about taramps has very mixed reviews from what I’ve seen so if there are any recommendations here around or under 500 dollars I’d be happy to hear them)
The id be wanting a professional install (excluding the alt.) since I’m simply not comfortable doing that type of power myself lol but I budgeted around 500 for the install itself which I’m not sure is too much or too little

Then I was also thinking to upgrade my door speakers and tweeters to the Sony XS-162ES which if anybody has any experience with I’d appreciate some extra reviews!

Thanks for any and all advice you may have!
