Product Reviews For Hifonics XXV Sampson

  • I like this amp a lot! I'm have it powering 4 Clif Designs CD1500C subs in ported boxes in the back of a Yukon XL. I'm running it at 2ohms and the power is outrageous. The sound quality is great and the bass is as load as you can stand. The only drawback is you will need an extra battery, large capacitors and 0 gauge at to power it. I would buy this amp again if I wanted this much bass but I don't I'm going to sell 2 of the subs and use 2 Alpine PDX-1.1000 for the bass. The new alpine PDX amps are the best amps for the money. I run my fronts with them.

  • this amp is a cheap knock off from the digital design Z2 series amp,difference is for 100 dollars more u are getting a way better amp and u can get it in a 14 or 16 volt series.the dd audio wil do a massive 8500 watts rms not peak the highfonics amp will barely put out half the power and is way to expensive.

  • I have this amp and it is no joke. Mike i dont know what your talking about this amp can push 10200 watts rms, those are the 14.4v figures. Anyway i had this amp pushing 4 15s and it fried all 4 of them. And yes they were wired correctly...great amp, just expensive....

  • This amp was not ment for SQ or music, it was built for straight Power / DB Drag. Mike from Boston, you put 4 of these amps on 2 T3 subs and did a 162.3 then you did 4 Z2's and jumped almost 5 db's?? I smell BS now. The Z2 is a good amp but it ain't that good.
