Spl comparisson. Pdx vs hifonics

This may be a stupid question. I have just never heard either. Alpine pdx 1.1000 vs bxi 2608 d? I'm pretty sure the alpine is underrated and the bxi is overrated. Someone correct me?

Uh, what ohm load will you be running them at?

At 4 ohms, the Alpine would be your choice since it is rated to give you 1,000 watts RMS @ 2 or 4 ohms. The Hifonics is only rated to give 850 and in real life you should expect 700 watts out of the Hifonics @ 4 ohms.

At 2 ohms, the Alpine is rated to give you 1,000 watts RMS and I believe the Hifonics is rated to deliver 1700 watts RMS. Although the Hifonics is overrated, it should still produce close to 1,500 watts RMS @ 2 ohms. In a perfect world, doubling the power would give you 3 decibels of SPL, so in theory you "should" be 1.5 decibels louder with 50% more power. In real life it doesn't always work out that well since you have electrical load, physical limitations of your speakers, and so on.....

Of course, 1 ohm is a no brainer.... Go Hifonics because I think the Alpine isn't rated to run at 1 ohm!

Thank you. The bxi is cheaper so that's good. I know the bxi will pull more out of the electrical system but that's alright.

As much as I like to bash Hifonics, I will say that it is affordable and it will do the job that you want it to do

my authorized pdx 1.1000 came with a birthsheet showing 1381rms

Was told you can up the fuse rating in the PDX to get more power, this is straight from Alpine, so I was told....
