New member Username: DrbworldPost Number: 1 Registered: Aug-07 | Hi Need some help on buying an amplifier. I wanted to power a Kicker L7 8" 450rms subwoofer in a free air baffle setup. In a BMW 3 Series E46. I read that free air require more power then sealed boxes and sealed require more power then ported. I was thinking of powering it with a Hifonics Brutus 1206d Amplifier rated at 900watts rms @ 2 ohms. Do you think this is too much? I heard good things about Hifonics amps but were believed to be overrated. Anyone have a suggestion on amps. What amps are the best? Can someone list best to worst amplifiers. Thanks |

And if you did use a sub free air it must be specifically designed for that (that kicker isnt), and will take a lot LESS power than it would in a real enclosure. Also look into other subs, square kickers have terrible SQ. Best and worst: https://www.ecoustics.com/electronics/products/articles/329117.html |

I thought kicker l7's were compareable to w7, xxx, etc. And how bad are free air setups? isn't it just like having the trunk act as a big box. I wanted to have nice fairly loud, deep bass. My trunk is a bass eater so cutting a hole through would sound louder wouldn't it. Does everyone thing this setup sucks, if so, i'll scrap the plans. What do people recommend. Currently I have a 10" Alpine Type R in a small sealed box pushed by an alpine mrp-450 at 400watts rms@2ohms in my integ. This system sucks. Thought about putting it in a ported box, but don't know were I can get a custom tuned box cheap. Any suggestions. Thanks |
