JL/Xtant system, sounds bad

Hello,

I had an 8" JL Microsub 8.1 in my car pushed by an Xtant 121m.... sounded GREAT.  I decided to go for a little more and a great deal came by - a buddy was selling two JL 10w0's in a box powered by a JL 250/1 for $250.  i couldn't pass that up, so i bought it and threw it in the car.  The car already had 4 gauge power and ground wired into it in case i ever wanted to upgrade.....

At any rate i put the 2 10w0's and 250/1 in the car and it sounds like CRAP.  i mean it sounds like there is 20 watts going to each sub....  i wondered if it was the settings, but the amp was pre-wired to these subs and the amp is screwed into the top of the box - i didn't mess with the settings when i got it from my friend.... i just hooked up the power, ground, remote, and RCAs for line-in.

what am i missing? i almost want to go back to the 8" Microsub and Xtant amp, but i'm wondering if i'm missing something... it has to be something simple, stupid...  i know an xtant 121m, rated at 120 watts will not out-muscle a 250/1.  am i missing something??

the 250/1 has two-channels, and both are wired up normally to each sub.... each sub is a 4 ohm unit.  i am guessing the amp would be seeing two 4-ohm loads, one on each channel.

help!

both are done.  i even tried switching the polarity on the subs, still sounded the same.  even tried switching the RCA's.  still sounds the same.  It sounds as if the amp isn't putting out the rated power.

The xtant 121m is 250watts @ 2ohms....125@ 4ohms. use this amp to bump your 2 10s Check how they are wired....make sure its 2ohms

That little xtant is a butt kicker

even without the LQ chip thing?  i don't think i have that chip....

so what do i do with the 250/1?  is it blown?  is it not wired correctly?  what am i missing?

thanks!

great, thanks!

question - i don't have a wiring diagram for the xtant amp, and while i [i]thought[/i] it was one-channel, it has two actual channels on it.... considering i had it wired 4-ohm mono on the 8" microsub before (using the left positive, right negative - or vice versa), how do i wire it for two speakers?  if i do it straight-forward and give each 4-ohm 10w0 to its own terminal on the 121m, will they see the 250 watts or 120 watts?  i don't know how the wiring internally of the amp goes...

in other words, if i wire up the two 4-ohm 10w0 subs to each have their own channel on the 121m, will the amp see a 2 ohm load? 

can anyone show me an example of a wiring diagram of how i should do this?  the box with the two 10w0's..... each 10 has its own speaker-connection cup on the back of the box... and each is a 4 ohm speaker.... so its two four-ohm speakers with each having their own terminal on the back of the box.

cheers!  and MERRY CHRISTMAS!  thanks all....

I do believe that is a mono amp but for ease of wiring they provide two sets of terminals. So you can set it up like you had it previously, a single 2 ohm load using one set of terminals, or you may hook up two 4 ohm loads, the amp will internally "bridge" it.

So here is the link to wire your woofers... https://www.the12volt.com/caraudio/woofer_configurations.asp

thanks!

so...

according to this, i share the negative of both subs, and share the positive, and wire them to the SAME terminal?  do i wire both negatives to the left negative and both positives to the right positive?  or do i just put them together to the same terminal?

or does it do what you say and "internally" bridge it, so i just wire them normally, each to their own terminal on the amp?  sorry for all the questions, i'm trying to learn!  thanks!  :)
