I use JL Audio TR650CSi component speakers with adapter rings in the doors. Exceptional sound from an Alpine headunit. Also had an Alpine 8" sub and PMX-F640 amplifier. Selling the sub and amp
I have a Gladen SQL 165 compo at the doors and a Gladen SQX 165 compo at the back with a Mosconi 120.4 and a Gladen SQX Extreme 12 VB sub thats playing on a bridged Mosconi 240.2.
