Thanks @jazngab I have been reading threads on this.
I still have the stock amp and head unit too.
Was hoping to just replace the sub and be done but looks like I may have to do a complete sound upgrade to get everything right.
Gonna be a steep learning curve, I'm no audio geek for sure.
Looking at a 5 channel v 1 channel, idk, it's all Greek to me. Time to dig in and research.
I am no audiophile myself but being I just did this upgrade changing the headunit, speakers, sub, and adding a small amp makes the sound system infinitely better. There are threads here and just buy what’s recommended, YouTube some videos, and do yourself a favor and order thru crutchfield. All can be done for appox. $300-400.
