I just want to say 'props' to briansredd for carrying those cabinets to every gig..i just got a pair of the jrx 115's, and i have to say they don't look like much on the videos, but these things are massive for a 2-way cab. Heavy too!!!...I don't have sub cabs now, so i just put them on a stand, and they get pretty heavy.p.s: I'll be doing the horn driver update pretty soon...I'll do a log on that.

hey i want to get (4) 8 Ohm @ 500 wattsubs. what and how many amps should i get!!!

No, it's not any louder

Somone please answer: 4 ohms better than 8? By better i mean, louder?

Also, when possible, try to run only one speaker per channel. This may require more amps, but think of it this way: if you put two 8ohm speakers in parallel on one channel (so you're now at 4 ohms), and one of those speakers gets disconnected or blows, the impedance on that entire channel changes and you could potentially damage your amp or your other speaker.If you just had one speaker on that channel and it blew, you don't have to worry about overpowering any other speakers on the line.

BTW everyone, try to avoid running an amp at 2 ohms. While they might be designed to handle it, there is so much done to the signal that it may not be as rich. Running at 4 or 8 ohms is best.

"Good video, thanks! Ok, here is one, I have an amp that has two outputs per channel and it said that the outputs are wired in parallel. Does that mean if I have two 8 ohms speakers hookup up to that one channel that I am pushing 4 ohms?" I can say with 99% confidence that yes, you will be doing 4 ohms when connecting two 8-ohms to both outs of a single channel.

Thanks for the reply, I have a Crate DPS+ 8 channel powered mixer. It has two internal amps that each power two channels for speakers. Here's a blurb from the manual "The jacksare wired together in parallel. The internal amplifier of the PCM+ Series candeliver its full power output into as little as 2 ohms. "

What amp do you have? let me have a look at the specs before I say anything
