Yeah as a newbie with Mustang system I was experimenting with different stuff but the first thing I did was buy Hertz MP 3", tweets and 6.5 plus sound deadening. Never used the C165F for rear fill on classifieds now.Makes sense
The AP8.9 is like 130W bridged, which is about the same as the OEM sub amp.
Then did the Kicker 200.4 till it failed six weeks later, upgraded to AP8.9, added Kenwood XR1001.1 and JL sub in sound deadened OE enclosure.....by which time sounded great.
Spent a lot of time tuning.....
