I'm updating my previous review due to some changes i've made to my system. My digital designs 3512 sc subs are now broken in. I have two brutus 1700 amps driving the two dvc 4 subs, coils wired parallel, amps are being presented with 2 ohms each. I can't say enough good things about these amps. My system is intended to be competition level and it's almost there. The most recent spl check was 154.3 in a '09 silverado ext. Cab without the rear seat.
For all the people i'm seeing that say hifonics amps are power hungry and their lights dim when the bass hits blah blah blah. You do not start building a system by throwing two huge amps and two subs in a car and go from there. Upgrade your charging system first! You can't expect to blast 1,700 watts off a stock alternator and 4, 6 or on some foreign cars, 8 ga. Charging system cabling. I have two yellow top dura last 1100 cca batteries and a stock hd 160 amp alternator and i have no problems driving two brutus 1700's and a zeus zxi150.4 (1,200 watts). No problems at all. I have gains set properly! This means doing the simple math to convert expected wattage output to ac voltage and setting the amp gains to that number using a test tone with your head unit at reference volume! If you don't know how to set up an amp, get some help! These brutus amps are awesome. And Sonic is awesome. I order on a Monday night and i have boxes on my step by wednesday when i get home from work.
