IA 20.1 Aint No Joke PT2!!

The number is nothing spectacular at all.....the box was extremely poorly built, and not competition worthy at all. Also, its in a '91 convertible celica that is leaky as fukk....lol Went from a 135.4 to a 139.6 on the dash, sealed up. Like I said, the number is nothing spectacular, or even respectable. The only thing I wanted to point out was the 4 db gain from the amp swap.

thats fine and a 140 isnt bad in a convertable lol outside of a few sidekicks that is loud lol. there was a cerwin vega stroker convertable mustang around here at one time with about 4000 watts on a pair of 15's that didnt even hit a 140 on an ac mic lol sounded like it would hearing it drive by but on the dash it sucked iirc 137.x is what it hit.

i would think u should gain from goin from an bx1500 to an 20.1, u should gain from goin 2 anything that put out decent power from an bx1500. bx is comparable 2 an good 600w amp. let see some real test wit some real amps and pic of the warden

which is why i said it should be no surprise //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif There are no warden pics, because there is no warden....right now

oh ok. so wha happen 2 the results from the comparison?no numbers yet?

In the first weeks of december, I can give comparisons hopefully.

results from what comparison?

BX1500 probably wasnt putting out more than 500-600 watts. In which event I'd hope the IA amp would gain significantly //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I think he's looking for actual wattage output numbers.

bx1500's do way more than 600 watts at .5 ohm.......here is a quote from kbaudio on the power output at 1 ohm.......so you know .5 will be a little more

981 watts @ 1 ohm (13 volts, 0.66% THD+N, 113 A current draw (66.8% efficient))

1360 watts @ 1 ohm (14.4 volts, 10% THD+N, 136 A current draw (69.4% efficient))

hmmmmmm, neva seen that kinda power out of 1

your comparing in-car tests with bench tests... 2 different worlds

impedence rise, voltage drop... a resistive 1 ohm load will nearly always yeild more power than a reactive .5.

From my testing, the 1500 runs much better at 1 ohm... wired to .5 it just gets too ineffeciant.

LETS keep the flaming down PLEASE!

The head to head comp is coming up, it's been delayed as I've been gearing up for 2 shows this 19th....

Keep it civil please!

we will, and i kno 2 diff worlds and we kno which 1 counts chris //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Ok, Ill agree with that, but its not enough of a drop to say that a BX1500 only does 500-600 watts...........sheesh......give it SOME credit anyway

From my testing, the 1500 runs much better at 1 ohm... wired to .5 it just gets too ineffeciant.

It may become more inefficient, but it still produces power........just has to draw more current

oh, and if my bx1500 only made 600 watts..........and generally speaking, when you double power, you gain 3 db (I gained 4)........are you saying that a 20.1 only produces around 1500 watts @ .5 ohm???

HOLY CRAP THATS WAY OFF!!
