Interior is ugly IMO

Shock Top is my drink of choice currently

Start out with brazing, then move on to stick/arc, then move to MIG. I would get on some welding forums. You're either good at it or you're not. There's no such thing as a mediocre welder. Thanks, I'm going to look into a cheap arc welder from HF and go from there.

We can detect changes in amplitude much less than 3db. Under the most commonly cited test conditions we can detect a change in amplitude of 1db. That said I'm not disagreeing with your premise.....small changes in amplifier power are not worth worrying about. Is that over all frequencies? Because (personally) I could not tell the difference between 137 dB and 140 dB in the low end range. He used the word changes, not absolute. Interesting, i thought i was going to get eaten up for my math up there

Alright, we'll do a little math here Say we have a consistent amount of current (amperage) draw at 100 amps and lets Say you were running at 13v. So to find wattage we multiply Volts*Amps 13v*100a= 1300w * .80 (for a Class D amplifier efficiency rating) which would come out to 1040w. So on the opposite side lets say you drop down to 12v 12v*100a=1200w * .80 = 960w In order to gain a noticable increase in output you need to gain at least 3dB. 3dB is the smallest a human can notice a change in output. and in order to gain the 3dB threshold you must in theory double your wattage.. so is that tiny amount of extra wattage going to matter in a daily driving scenario? The short answer is no, it would not matter what-so-ever. SO pick an amplifier that fits your budget, is aesthetically pleasing, and is in your power range. Granted what I've said isn't 100% perfect, but I hope you get the general idea behind it all.

So... you expect to see 14.4v at all times when running an amplifier? Also 1% THD is inaudiable especially at sub bass frequencies, I don't recall how much to go up to hear it.. but its a lot..

cea- 2006 compliant really doesn't mean anything...

nothing real important.. just to learn and make stuff..

I'm looking to begin to learn to weld.. Is mig welding a good start?

I'm trying to get ahold of him.. he lives like 5 mins away from me

I used Titebond spray adhesive the medium and it came off when it got hot in my car.. like i said look for the toughest stuff possible spray both sides, let it sit for about 20 seconds then push on with pressure.

Ensure you get the tackiest you can. Spray both sides and let it tack up

It's windy here 24/7 lol

I had some good wings in FL at Hurricanes though. i think they're a chain too.

Enjoying those strong fundamentals are you? Still better than the actual NBA Whenever my friends and i go to bdubs, we watch WNBA and every shot they miss, we take a drink.. and keep going. Funny, except being a bdubs. What a fucking waste of a chain. Everything about the US I hate is epitomized in that shit hole. Yeah, not many local places around base. kinda shitty, i hate chains.

Singer Alternators!

Oh, so because I choose to run my amps below 1 ohm I magically can't afford power for my woofer? Odd, I have over 2x rated power on it........ X2... -

Looks great, only thing I would suggest is ditch the big ole dowel rods and go with good ole all thread.

Rounding box edges help increase SPL?

Not really, smoother airflow = good- 26 replies

I'm currently located in Wichita KS, but i'm from liberty.

Hey man just noticed you were from KC, where abouts in KC?

Difference between those companies is that Fi does almost everything from the ground up on all of their woofers.. no direct drop in bull shit.

Hmm... I'll chuckle a bit, but also F you up since that is my sister ... lol Your sister is cute Kidding.. Kinda.. not really.. but nice camera!
