Selling a perfectly working condition set of SQ Xtant Marathon Series Amplifiers.

I got these both local from the orignal owners who both bought them brand new back in 99.

Both amplifiers are set to full range I do not have any xover cards. These amplifiers are pretty unique in the fact you used Jumpers on the internals of the amps to adjust Gain sensitivity, Xover settings ect ect.

The Xtant 404m was installed in dudes BMW but never hooked up, He pulled it out and had it sitting in his garage untouched for years.

It is in great condition and works 100% perfect with a few scratches here and there on the chrome.

This set would be great for someone wanting to go Sound Quality. These amplifiers have a really low THD.

Specs for the 404m (for gut shots head to Ampguts)

50 x 4 watts @ 4 ohms

100 x 4 watts @ 2 ohms

200 x 2 watts @ 4 ohms

Fuse: External 50A

Next up is the Xtant 121m Monoblock Amplifier.

This lil guy is small but puts out a very stout and clean 250w rms at 2ohm

Again small scratches in the chrome, This amplifier was used on a Soundstream SPL12" sub the seller gave me a demo before I bought the amp and it sounded very detailed in bass responce and got pretty loud for 250watts.

121m Specs

1 x 125 @ 4 Ohms

1 x 250 @ 2 Ohms

Freq response : 5Hz to 50 kHz

THD:

S/n ratio : >100db

Damping factor : >200 (@100 Hz into 4 Ohm load)

Fuse: 1 x 30

dimensions : 11" x 1.8" x 8 "

Asking 250.00 shipped

Or 145.00 shipped each.

Thanks for looking!

 
Im interested, but the gain setting has me kinda ???
Gain Settings are tradition you turn up a nob to adjust the gain.

what the jumpers do is allow you to set the +20 +10 0 -10 -20 db input sensitivity.

Basicly like a boost.

Xtant has a PDF you can read up on their site. I have the Manual for the 121m that also has the 404m aswell.

If they do get sold seperate I'll make a photo copy of the manual for the 404m.
