my aim was to use this amplifier with my sony mhc vx 701 hifi music systems speakers impedance is 6 ohms in my car which were lying idle it is working perfectly so far and i can use my beloved home speakers in my car now the hybrid dual woofers in my sound boxes produce enough shock waves to rock my scorpio but remember one has to put the low pass filters off while playing home speakers with car amplifier because home speakers are full range speakers dont forget to use proper wirin
