My 87 S10 Blazer Build

I have an 87 2dr s10 blazer that I just finished installing my system in and I wanted to hear some opinions on the equipment. I have 2 pyle PL463BL 4x6 custom installed in the dash hooked up to a 200 watt virtual sound labs amp. Four NB4 power acoustic tweeters hooked up to the four channels of the head unit. Two PL1090BL pyle 4ohm 10in subs 1000watt peak subs bridged to the jewel of my setup.. my rockford fosgate 800IIa amp. The head unit I'm using is the 80x4 watt pyle PL43MU. That's what I got in there for now but I'm not quite down with it.. just ran out of money lol. I want to custom mount two 6in midbass woofers where the rear speakers go and replace the virtual sound labs amp with a four channel (probably a rockford fosgate) then hookthe 4x6s and the woofers up to that. Ithink ill have every audible frequency coovered after that! Ill post some pictures later when I'm not on my phone
