I can say it boosted up my Subs 1 or 2 more times than what it was!! Really worth the price and I like it. It worked the same as good as the other soundstream I had. I would recomend it to anyone else if you have any problems with it, its because you dont know how to install it or you didnt tune something the right way.

I like that you can tune the inputs to the amp and still add power through the rcas. Best thing for a cheap stereo.

I DONT OWN A DBM-800 BUT I JUST ORDERED ONE . I INSTALLED
ONE FOR MY BUDDY ,OMG IT DOUBLED MAYBE TRIPPLED HIS BASS, I LIKE THE WIDE FUNCTION . IF YOU LIKE BOOMY MUDDY BASS,OR LIKE TIGHT NARROW BASS . IT CAN BE ADJUSTED TO YOUR WHAT EVER YOU LIKE . IT HAS A BUILT IN LINE DRIVER TOO.
BOOSTS OUTPUT TO 9 VOLTS.

WELL I CANT WAIT FOR MINES.

THANKS

I bought this a week ago and it works well, i just wish the subsonic filter went below 35htz cause i like to feel it hit low and the filter makes it tough.I sends a nice clean signal.

I've owned the epicenter, and the soundstream bx-10 and this absolute sounds just as good as the soundstream unit... and that to me is better sound and more tuning options than the Epicenter. You just have to to tune your head unit and amp and boxes of course to get the most of this device.. raise the Hz on your low pass filter in your head-unit for better sound.

I added the DBM800 just to see if it made any difference in my bass and let me tell you it sure did, my bass notes are slamming hard now. The extra voltage on the built in line driver sure does the job. i like the way you can make the bass hit narrow and hard or wide and boomy.

Was not what I expected necessarily. Rather disappointed with the quality of the audio once filtered through this. I would rather have my 50$ than this, sure it looks nice, that's about It.
