Re: I think this is Alpine 9835 or else with Sedona Preamp
this sedona stuffs are new to me.i guess the guys at YKF Audio Shop introduce the brand here in Brunei...they got the first info of it somewhere in Thailand where the competitors there had used sedona amps to pumped their Solo X + L7 which were a big hit for 'em.guess sedona amps really kick ass!!!
