Question: what is the maximum amount of speakers that could run on this ?
Document: I bought this unit for my son's car. I wanted a 4 channel amp so I could boost output from all channels without the cost and hassle of multiple amps. This produces plenty of power and is very stable. Warms up some, but so far I've run it for hours at a time without significant heat or any problems at all. I chose to wire this using the speaker-level leads from my head unit because I wanted to retain the ability to fade front to back.
Worked great for the time i had it. Not one single complaint. Delivered great power and never let me down. I was powering a small 10in 350watts sub. I could have very easily powered a second without a second though. Would definitely purchase again.
the speakers can handle 110 rms.
I am also very happy with the speakers!
I dont need anything more. I first thought that I would not have enough power to run the subwoofer, due to the amplifier pushing only 180 watt rms at 4 ohm`s. But I was wrong, I am getting pure clean deep bass without distortion(that DD mini 8inch subwoofer is a little beast, sounds like a 12 inch, bass response is instant due to small size)).
Amp performs great, much better than my factory GM Booster. I have it hooked up to my 4 Pioneer speakers that were swapped in over the factory ones.
This is a great amplifier, I've had it for a year now. I blast my speakers every day, and you can't beat the price. Everyone that rides with me loves my stereo, including my 4 sons. Highly recommend!
I have this amp in my 2000 Ford Ranger and it works great. I have it hooked up to my 4 regular speakers (doors) and two subs. I didn't want to put in two amps, so this works for all my needs. I bought the two channel version for my wife. Highly recommend this amp.
I used this amplifier in my F150 supercrew, behind the passenger side rear seat. I wasnt sure that it will fit, but it fit with plenty of space available. routed the wires from the front and connected to the speakers, sound is great, 100 times better than it was before, even when i already had upgraded before the head unit and speakers.I dont see the unit getting hot or anything like that.
2005 F-150 Supercrew, OEM headunit, no sub, replaced all for speakers with Pionner TSD6802R and this amplifier. The decision came down to matching 60 watt RMS between speakers and amp and matching name brand. I would like to think when pioneer is testing/developing their speakers, they are using their own amplifiers. Seems to me the speakers would sound as close to what pioneer wants them to sound like only when they are hooked up to their matching equipment.
Answer: The recommended amount is 4 speakers, you can add more but the sound quality wont be the same. I purchased this AMP near a year ago and the sound quality is very nice I have it connected with 4 Pioneer speakers 400 watts each and they sound amazing, if u are looking for nice clear sound this is your AMP. (Recommend Pioneer speakers with it for a nice rich clear sound)
