dissapointed with this setup!! very angry..

Mine likes low inputs

I've experienced with several Hifonics amps from TXI to the XX/XXV and all of them required me to turn up the gain much higher than most other amps ive had.

Txi 1008 , Bxi 1606, Bxi 2006, XX-Hercules, and the XXV Colossus.

With my zx2500, RF T20001, and Sundown, my gain was usually set at 1/4th.

And these amps were all used with Alpine HUs.

I use Alpine Head Units too.

Bu the amps used are the Goliath and The Maxximus. Was using a line driver but voltage input was much too high. They seem to like 1.5 volts to 2.8 volts for me. I havent used the smaller Hifonics amps.

All the x-100s I have installed have had terrible bass output unless the gain was cranked.

Take that for what its worth.

didnt read the last 4 pages.

check the HU settings, check and make sure the subs are in phase

Ha ha, not at all. I like those guys.

Just stating that the amps I tested are a little different and I have not had the chance to test the other models.

Of course The setup will effect this as well. Battery voltage, ohm load, Box rise, power compression, etc....

So now that the setup is better, how does it compare to your previous?

Because I got a pair of BNIB 2008 15" L7s for $100, essentially $50 a piece. Zx2500 isn't stable to 1ohm, so I sold it. I also got another deal on a BNIB XXV colossus for $450 . Couldn't pass up these types of offers, so I jumped on them and then swapped those L7s for dual 2ohm.

For the 1948462352748573562 time the zx2500 is stable at 1ohm I have ran mine daily for over 2 years at .7ohm and have ran them at .5 however at .5 they are very tempermental.

I should have said, it was not stable @ 1ohm in my situation because i didn't have the proper electrical to back it up......

You are going to slowly kill your Hifonics mounting it to sub box. Board vibrates and brakes a mosfets leads. Most common problem with these amps.

i have no other option as you can see

is that box sealed?

or is port facing the dash?
