So I finally bought all the pieces for aftermarket subs to go along with the infinite audio system and the touch screen display.
2 Kicker CVT104 10 inch shallow mount subs
Kicker DX 1000.1 w/bass knob
Raptor 4 gauge amp kit
All enclosed in the RT duel 10 inch sub box
$15 line out kit from best buy
After a couple hours of bolting, unbolting, removing toyota parts, hiding wires, and tuning the amp, the subs were finally installed.
With the knob hidden in the side storage (picture is not mine, forgot to take one before i posted this), the subs sound amazing and couldn't be happier with the fit and performance.
All i have left to do is put some fabric over all the metal parts that are now showing because I removed the plastic storage behind the seats, but that is soon to come.
If anyone has any questions let me know.
