I just tested the sub out free air for a minute using an audiobahn amp that puts out 400watts at 4 ohms. All I can say is, I can't wait to get that 1400rms amp!!!

400 audiobahn is probably about 300 real world. It needs some real power.

oh gee, look another si post by showrides...big shocker

your audiobahn sub put out 400 watts to your si sub huh?

you have a link for this subamplifier?

It's an a8000t. You can look it up.

Thanks for letting me know.//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Oh yeah...I'm not extremely computer savvy...but I believe most soundcard outputs are 1/8" mini jacks. So then you'd just need a mini-jack to RCA wire, and then connect that to the inputs of the amplifier.
Something like this, then connect the inputs on the amplifier to these outputs via regular ole RCA.

Will my amp work with that cable? I was looking at a picture of the inputs in the back and it didn't seem like it would work.

This is what the description said.

Balanced XLR and 1/4" TRS inputs

Let me know if that was the right converter to get or if I need something different.

Thanks once again.

YOu'll just need a 1/8 to 1/4 phono adapter in stereo.

"I'd be interested to see what the Behringer could do but it's definitely not made for HT. A few things to point out: 1. It has to be rack mounted for proper cooling. 2. these types of amps usually have pretty loud fans moving the air through them. 3. It doesn't have a low-level RCA input which is a huge downfall. Did you look at the connection types? It only takes XLR or quarter inch connections which no HT receiver or power amp comes with. It's meant to be connected via a sound board. I just don't think this will work. The BASH amps are excellent amps. You'll see them listed on some of the better powered subs out there (in the $400-$1000 range)."

That is what someone else told me on another forum who has had a lot of experiance with home theaters. Becasue of that I am probably going to buy two of these to power the mag.

You think buying 2 of them and hooking them together to run 1 sub is ok for a HT?

That guy, frankly, has the complete wrong idea.

Yes, Behringer and other pro audio-derived rack amps need some special considerations in interfacing XLR to low level RCA found in most receiver outputs, but there are workarounds for it. And there are replacement fans that will solve the fan noise issues.

The fact is that Behringer and QSC amps are some of the most cost-effective solutions for powering relatively high power home sub setups //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Well tomorrow I want to make my choice. I will either go with the behringer or 2 of the other amps I showed. Does anyone else here have an opinion? JimJ you seem to know what you are talking about. It is only about $100 more for the bash amps, so price really doesn't matter that much. Just let me know which you think would better power my sub.

 

[Showrides]

I think i am going with the behringer. After reading the stats on the bash amp, I found out I wouldn't be able to hook 2 of them up to my one sub.

Well, I am going with the behringer for home audio duty to power my e8a sub, infact I am looking at the amp right now.

Did you post in another forum about how much you spent on your system? I am pretty sure I asked you what you thought of the behringer amp.

 

[ballstothewall 10+ year member]

I am on this forum, SSA, CarStereos.org and Automotiveforums.com

I might have, I don't remember, but I will have to hold off on that review till I get my crossover in and get the behringer hooked up permently.

My initial thoughts of the amp hooked up to my mains...

****, the fan is NOISY, but it moves alot of air.

Heavy as hell (40 pounds, but hey, if it pushes that much current, its got to be heavy)

Hella powerful, don't even have to take the gains off minimum basically for my mains if I have them hooked up to it.

*edit* The downside is I can't get full power out of it here in the dorm room cause I would blow the breaker... Sooo, its prob alot bigger than I need, but hey, you can never have enough power!! *Tim Allen Grunt*

To me, an audio amp is an audio amp.

It has to be rack mounted for proper cooling.

Not true. Here is my four proamp stack running without any rack. Amps sitting

on top of each other. No big deal.

these types of amps usually have pretty loud fans moving the air through them.

Some proamps have variable speed fans. At loud volumes usually you don't

hear the fans, at low level listening the fans are spinning slow, less fan noise.

The reason pro amps have fans is because they pack a butt-load of power into

a small footprint, RU chassis size. If the same pro amp were designed to be

fan-less, the amplifier would be 3x bigger in size.

It doesn't have a low-level RCA input which is a huge downfall.

Huge downfall ? You can get a cheap RCA to XLR adapter cable.

It's meant to be connected via a sound board.

no

I just don't think this will work.

Pro amps have gain controls so if your RCA signal is weak, turn up amp

gain.

The BASH amps are excellent amps.

yes
