According to Pioneer this amp is 2 ohm stable. So can easily up to 8 speakers with this amp. Each would receive 62.5 watts rms, and 125 watts peak. Pioneer specs below. Maximum Power Output at 2 Ω 250W x 4 **Q: i have an all in one sub (integrated amp), and am running 4 speakers, is there an output for this, or do i need to run my sub off the head unit.** A: I did not see a feed through rca on this amp. So would need another from the head unit **Q: Cuántos ohms es este amplificador 4 / 8 ???** A: I don't know for sure but I THINK possibly 8 **Q: What size fuse should I use on my main power wire?** A: That all depends on your wire size, 4 gauge is safe to run 100 amps but i run a 250 on my zero gauge. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Pounds my door subs, awesome amp *by on Reviewed in the United States May 31, 2023* I'm no car audio expert and I don't have any testing instruments to read any data off of what this amp produces. I wish I did. But what I can say is that it fired right up as soon as I connected all the wires and started tuning it to my ears, and I am extremely happy with its performance.Currently it is driving two six and a half inch door subs in the front and two eight inch door subs in the rear and I got to tell you it really improved the sound of my system. I like it a lot. The bass notes are very clear and distinct. Recently I switched one of the 6.5" Skar front door subs into a small ported enclosure underneath the rear seat. One 125w RMS channel from this amp really pumps out some good bass from that little box. I'm going to take the other front sub out and replace it with a woofer like I did with the other one and make another ported enclosure for underneath the other side of the back seat. I bought an install kit by Installgear on Amazon. It works great and has no issues. I'm very happy with the $97 I spent for this kickin little amp. Thumbs up. ### ⭐⭐⭐⭐⭐ Great Value and Sound Quality *by on Reviewed in the United States April 10, 2024* No complaints at all. Very affordable along with very good audio quality. I used this to power four Pioneer 6x8's. WOW!!! Turns out I may have over powered the speakers a bit (Pioneer 240 Watt Max), but the sound was amazing. I have used this amp for just over 3 years, still non stop performance. Pioneer makes good stuff; best bang for your buck. ### ⭐⭐⭐⭐⭐ Great *by on Reviewed in the United States July 23, 2026* Can't really write a review on it.
