I have to T1000-4 and T600-4 and love them very much. They have never gone into protection but my T1500-1 has over heated and needs to be vented decently. These 3 amps together make any car sound like a concert.
They’re very nice sounding amps
Can we get a "Yeah Boiiiiii !!" ?
Jeah!
I have been driving since 92. My first amplifiers were my Rockford Fosgate 200a4 and my 301S... I still have them both and use them every day. They have been in countless vehicles and still sound as amazing as the day they were new. I recently added the Prime 1200-1D to my pickup and I have to say, all the years later and Rockford Fosgate is still every bit as good! Very happy! I am an SQ guy. Always have been.
RF is still putting out great equipment!
I have t1500 and 2 type R 12s. Its won competitions. ALL electrical upgrades
These amp are amazing. Can't wait for you to get the new prime r2 amps one of these days.
25Hz to Life me too
Dude I got one on my two Memphis m6 10s it’s an awesome amp. I had to change out my other amp just keep up with it😂 so my shitty pioneer is now becoming the Rockford t400-4ad
These amps had to grow on me but I really like them now. Great vid yo!
I actually feel the exact same way and you’re too blame lol
50% eff.??? No way !?!?!?
@@96kylar it's an A/B.... what do u expect?
I picked up a t400 recently for $100 on fb basically looks new everything works.
I own a Rockford T-1000.4 ad, a Crescendo 1100.4, a Planet Audio AC 2400.4, Boston Acoustics GT4-100, and JBL GTO 1004.4. All are very powerful 4 channels but it's a close fight between my RF T-1000.4 and Crescendo 1100.4.
Man I love the T series amps. I've gathered a small collection and don't ever plan on selling a one
They’re great amps for sure
That sounds amazing your wife is going to love her new sounds
As usual Rockford always rates their amps right. Sounds pretty sweet too.
Fo sho!
Great video, love these amps they just sound sooo frigging good
I do too!
Great upload man!!! If there was ever a complaint I had on Rockford amps, it would be the excessive amounts of thermal paste used. They put so much on there, makes repairs take forever, especially if you have to remove it all and reapply your own. Other than that, Rock on 🤘🏽 Rockford!!!
The3rd ERA paste for days!
I would rather have too much than not enough.
Thats a beauty👍talking about running hot the first prime amp I had was the 250.1 it was ab class ran so hot you couldn't touch it the 750.1 and the 1200.1 are d class they dont get hot at all now the new 250.4 runs hot with all channels loaded at 2 ohms each. Cool video cant wait to hear the Hyundai 👍
A/B 🔥🔥 😂
great amp can't wait to see the install
Yea buddy my guy HiFi putting that test bench to work ol Rockford Fosgate makes some beautiful equipment you gotta love'm #TeamHiFi
Yeah boy!
One of my favorite amps
Thank you Vega. You saved me from changing my name to Jones...
LOVING THE CLASS A/B POWER... Might be my next amp for my mids and highs.
Mr Jones and me...
I love the current model fosgate. Wasnt much of a fan of the previous t series. But current I have every amp but the 1000.4 I run a 2500bd in my tahoe with a 600.4 I use a 400.4 and a 600.2 in my garage heck I just gave my son his first amp in a 400.2 all t series. My t1500bdcp is my fav of the series. Just does the job and does it well. Cool vid as always my friend.
These are solid amps
Kicker ZR series just called. They want their efficiency back.
Ooooh shots fired 🔫
No kidding. That efficiency was rough.
What year was it manufactured?
I didn’t actually look at the manufacture date on this one
So which amps are better out of the R2 500.4 Prime Class-D amps vs these 400.4 power series-AB? Great video.
Both of them seem really solid. The 500.4 is probably going to give you a little more power while drawing less current compared to the 400.4. If both of them have all the features that you're looking for and physically fit in the place you want to mount it, just go with the one that you like the most. A few differences I see is that the 400.4 is quite a bit larger in size and it does have steeper crossover slopes than the 500.4. There's also a difference in price.
Thank you Boss I went ahead a went with the 400.4
So do I just run my front and rear speaker wires from the amp to the back of the radios wire harness?? And run my RCA's which will be my rear and front RCA's from the amp to the back of my radio? Thanks for the help Boss really means alot.
@@jefferyglover4295 Yes.
You need to get a acrylic top for that amp
Thanks Rob!
Ace ace ace! Been looking for a video coving this for ages! Ok….here is my question:
If you have 4x50w amp and you only use 2 of the 4 channels, does this mean you have slightly more power on these used channels given the decreased stress on the power supply??
The reason I ask is, in AV, they rate 2 channels driven because when all channels are driven the output of each is significantly reduced. So, by contrast, if you only used 2 of 4 on a multi channel amp, do you get a bit more power from the amp??
This is not a question about bridging the amp, just about leaving 2 channels unconnected like when using an AV amp in stereo, will you get more power?
Yes you typically get a bit more power when all channels aren’t driven because it’s less stress on the power supply. In my experience it is not a huge difference maybe like a 10% gain
Where we're going we don't need no stinking efficiency!
Phillip Bainbridge good ole class a/b
Oh yeah.... im liking that amp .. , can't wait to repair one 😀👍
Dont hold your breath!
Very Good Rockford Fosgate SQ
Hey Hifi! Great video, as always. Thanks for testing this "Older" model Fosgate amps! I don't have a T400-4 amp, but I do have a P400-4 amp, which sounds awesome, and loud. I bought it refurb for $189, on Crutchfiield, years ago!
On a side note, I have a question for someone like you, who knows a lot on this subject... Can I test a P10002 amp (2006), which has a 160amp fuse, with a 35 amps Power Supply? I don't have a car now, to test it! Will I blow the Power Supply, or damage the amp, if I do so?
Thanks for your expert advice.
You can test the amp to see if it powers up, KEEP THE VOLUME LOW. That power supply will not power that amp well. Your 35 amp power supply is only going to allow you to output about 380 watts. You will most likely blow the 35 amp fuse. There is a slim chance you could damage the mosfets in the amp's power supply.
You can test for functionality for sure, but like Chuck said you should do that only and not try to play it on the PS.
Now, you could put a car battery between the amp and the power supply and get some volume that way. The battery will not charge fast on that power supply so dont play the amp too long, let the power supply charge the battery.
chuck Miller Thanks for the advice! I just plan on testing it, and playing it a little at low volume, to see how it sounds. Do you think I can damage the P.S. or the amp, just by powering on the amp? That's my main concern! I've played a P5002 amp without problems, but it only has a 60 amp fuse, not a 160 amp fuse, like the P10002 amp.
HifiVega Thanks Hifi!
How do i reset it theres no fuse power light went off some how cant reset it...
Love these amps
so do i..I have the 2500 bdcp & the 600.4 & I love em
Me too!
I got one for $160 stole it. barely used in box with no scratches cant wait to add it on my new set of kappas.
That’s a deal for sure
Just found my make out track !!!
laser temp doesn't work on reflective surface fyi
NICE!!!
Hello sir,
I was wondering if this amp could push a total of 8 decent 6.5 high end door speakers?
Easily
Thank you sir!
Hii, nice video , can T400X4 4 channel amplifier be a good compatible with Morel Virtues 602 components in 2 way passive setup
Papai Palit it’ll work great with the morel comp set
Any way to make the amp or any amp more efficient? Class ab?
Make it class D lol
@@HifiVega lol!!!!
Purty good lookin juice box.
Not Pioneer level doe 😉
@@HifiVega I'm purposely overlooking the facetiousness of this comment and will accept it as your true opinion!
Pioneer Man I substitute your reality for my own 😉
Wjy can't testers test the individual channels at 4ohms like 90% of useres will run?
Because 8 ohm mono is the exact same load as 4 ohm stereo with less wiring and it’s easier to load all the channels down when it’s bridged because you don’t need to wire up as many resistors
I've got that same pioneer head unit
It’s a solid hu for the price I think
I have alpine type s speakers. should I get this amp or something with more power. right now I have a Polk Audio 660.
This amp would have plenty of power for that component set
Which is better? JL Audio Slash 300/4v3 or this RF T400.4
That’s a Sophie’s choice! I’d go RF, but you won’t be disappointed with either.
hello , can you do amp/DYNO ON BASSFACE DB1.4 6000w 1Ohm Class D Monoblock Car Subwoofer Amplifier Bass SPL Amp
How does this stack up against Sony's XM-GS4?
Imo it’s better in almost every way outside of maybe being too big size wise
What where your gains set at ? So I can copy your set up
These are set at about 11 o clock, but you really need to match the gains to the source unit that you’re using.
Thanks.
Aloha from Hawaii!!
Where is the fuse sittning?
I use a combo fuse block for power and ground on the test bench
Which one do you recommend me for sound quality, this t400-4 or jl slash 300/4?
I’d run either in an SQ set up
@@HifiVega so, what amp do you recommend me a/b for better sq, I have AF gb60 and gb15
Cool amp!!!
that rockford tech got a little carried the f away when he put on the thermo paste don't ya think lol
Fo sho, but it’s like this on all the Power series amps I’ve opened up and seen. Surely it’s gotta be on purpose
I had a 500/1 power that got so hot u could smell it
The RF amps do run hot on the outside, but they’re designed to keep the heat away from critical components
Thinking about getting a 4 channel prime amp.
I have one, it's great.
Can’t go wrong
Loved mine, get it. My 300X4 was in the car for 4 plus years never a hiccup.
@@thenotoriousrvh6091which 300x4 Boss? I see a few of them, I see the Prime Line then I see a R300x4, just seeing which one.
I got t600 and it's the shiznit
