I have 2 MTX Thunder 8000, Single voice coil subs powered by a Hifonics Zeus 1500.1D i have the subs running in parallel, I have a Kenwood KRC-1005 Head unit, and a 6 gauge Power wire running back and a 6 gauge ground. I am using a cassette adapter that i plug into my ipod as that HU is about 15 years old. On youtube i have seen one of these subs running at 400 watts RMS Flex like crazy
I Have 2 of them running at 500 RMS each. and i cant even get my tassel to move on my rear view mirror. The most i can get is a little trunk flex. Is there something i am doing wrong ?
