My Test On The Bxi2608

[Ali1 10+ year member]

lots of rumors saying this amp is overrated, yet no proof, no test, no pictures. I recently installed two bxi2608s on a pair of L7s and came to the conclusion that these amps do rated power at 14.4v. if you feel otherwise, please post your results so we can compare. Nonetheless, gain was set my DMM, while bass on headunit at -7. Amplifiers were set at 50.9v according to the gain tutorial.... and here are my results:

VAC= 66.1

CAC=16.89

66.1 x 16.89 = 1116.429 rms

66.1/16.89 =3.9ohms (Reactive Impedence)

Voltage dropped to low 13s

amplifier did 1116.4 @ 3.9ohms, yet its rated at 850 @4ohms

further results.....

1455.1 @ 2.77 ohms

985.6 @ 5.4ohms

1803.1 @ 2.3 ohms

1319.7@3.03 ohms

Pictures- wires are messy, but its temporarily until i figure out where i want everything. More results with lower ohm loads soon to come after i get my DMM back

wow can those kickers take that much? i have two 2006 L7s on two brutus 1606Ds, and i can pound on em pretty good

Did you use the peak hold function?

no, i took the picture while they were constant.

I highly doubt they will take 2600rms daily, buti wanted headroom

BonesNinja, he can't get his hands on MDF so he's only using birch as of now

IMO an amp test isn't complete without an oscilloscope.

Finally someone posts proof to back up their claims about hifonics amps //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I don't know why nobody seems to understand that unless you can account for power factor your test is basically meaningless.... //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

we always go around and around about why this test is inaccurate.

Bottom line is this is the best way we have, there is no other economical way to test. Until someone makes it possible to get a constant load for teh cheap this will have to do.

also ive did testing with my fluke/craftsman dmm/clamp meters and putting the meter on peak hold, as long as nothing freaky goes on , like a wierd spike at the beginning or end of a burp. And you don't do anything stupid like roll the volume up really quick and then stop. the results are very close. Peak hold works fine, as long as you know what your doing.
