Have some SQ stuff if you need pm me, If it’s your first time stick with the basics. You need these three things assuming you have a decent 4.1ch head unit
A 4ch 1000W Amp (Pioneer, Sony) don’t go for anything else as fla fla Malaysian brand is not up to the mark and the European ones are cost prohibitively expensive.
Sub woofer, sealed box (ported will have a lot more umpf but not the finesse you would desire. A 10" will suffice, get either JBL or Champion series pioneer (a bit more expensive than the regular stuff) 12" will work much better.
Components, now this is where the magic happens, need a good set of crossovers and mods, feel free to splurge, Go with pioneer everything else is hyped up for extracting more money out of you.
