Questions & Answers

Would it be accurate to have a silvery product picture if the description displayed another product (which is what the manufacturer shows on their site)?

T400-This amplifier is marked as such The face is 4 out of 4. My amp is completely different from the one I had previously. RF amplifiers from this era can be quite difficult to find nowadays. Amps from the Power series are good and I use only these. As of 2001, I was running a Power 1050. The Punch series or even the Prime series are not something I pay attention to.

There are two on my HU. The preamplifier has a 5V voltage. My amps hiss when set to gain 6 or above no matter what volume I set them to. More is better when it is higher. Can you advise me on how to make my voice ?

Sonic Electronix's guide to Amp tuning was helpful to me when experiencing the same issue. My hissing stopped as soon as I followed the guide. There's a problem with the gain. I guess I turned it up too high. If you are not playing music on your HU or plugged into it, you should not hear any hissing at 75% volume. It appears that you set your amp to pair with your HU properly in this case. It is possible for you to spend the money to have it done by a professional, but my suggestion is to find some online guides that will help. It helps you tune your amp to work with your HU by presenting a sonicelectronix amp guide. It is as simple as going to Google and looking at guides.

As a newbie to the install world, I appreciate any help you can give me. My two hertz hcx 165 speakers are powered by this amplifier. How can I get the most reliable install kit?

Beyond the fact that some of their products are of high quality, I have always used Rockford Fosgate install kits. Fosgate was the brand of my entire system and I wanted as much of it as I could match. The only parts from another manufacturer were the headunit and the sound damping.

Is there a treble knob included in this or do I need to purchase it ?

The treble knob on an amp has never been seen before. The bass knob is not included, but if you meant that, then it doesn't Highs and mids are supposed to be the main focus of this amp.

Selected User Reviews For Rockford Fosgate T400-4 Power 400 Watt 4-Channel Amplifier

Today has been the most difficult day for me in a long time
5/5

It has been almost 2 years since I purchased this Rockford Fosgate amplifier and I am exceedingly happy with it. My current amp sounds better than amplifiers that are much more expensive. I have never owned a cleaner or louder amp. I have never had a problem with the protection mode, even though it was in my trunk through Texas summers exceeding 100 degrees and I frequently drive up to an hour with the volume up. In addition to driving JBL goods in my door and a 12" RF Stage 3 sub in my trunk, it also controlled my door speakers. It did not overheat or hesitate once, even while playing very low bass notes at very high volumes. It was properly set up when I got it 2 years ago, the crossovers and gains were adjusted properly, and I haven't had to touch it Basically, my car was broken into last night, which led to this amp being stolen and my subwoofer being stolen. So today is my least favorite day in a long time. It made me cry so hard for losing the amplifier. It is true that worse things can happen in life, but the fact that this beautiful amplifier was taken from me doesn't make me feel any better.

Item number T400- A perfect 4 out of 4
5/5

The pros are I am - Stylish and of good size* br - I have a blue led on my charging dock and deck to match the gps charger - I put this under my seat and it fits perfectly - I used a perfect 2 6 with no problems. There are 5 Polk MM fronts and 2 Polk MM backs. A full 25 Polk MM rear is shown here - It is fun to not see those phillip screws* - The machine runs warm. It rarely gets very hot or really hot. Please read carefully

- It would have been nice if there had been an out for the I find running the amp a great addition to my polka shirts. It would be good for everyone to own It would be nice if they could have amps again the way they did with Clarion and Alpine due to Fosgate's dominance. This is the next best thing to JL Audio Amps if you cannot afford them.

Oh my gosh
5/5

It's impossible for me to express myself in words. Despite the small amp, this thing has insane power. Having built sound systems for many clients and hearing many amps, I am a little familiar with the industry. My experience with the following brands includes JL Audio, Kicker, Phoenix Gold, HiFonics (as well as Crunch, MB QUORT, and AutoTek), as well as lesser known brands such as Power Acustik and Performance Technik. A couple of the amps I've used have been extremely high powered to the point where I have questioned their ability to provide clean and loud music while keeping a low profile and remaining My car is a 1998 Cadillac Catera, and I replaced the stock Bose sound system in my car with Rockford's 6-speaker system. There are five components in total. An Alpine MPR-100 amp was used to power all of this While I think the Alpine is a great amp for its size and power, the Rockford Fosgate T400-B is more affordable and has better sound quality It was a complete failure on 4's part. The installation was easy, as it was easier to install than the Alpine. It has a higher build quality than the Alpine, and everything feels worth the price. screw terminals are probably one of the best I have ever used (unlike the allen wrench style screws from JL 500/1 that eventually become stripped). An allen key and a screwdriver are all you need. It's good to know you're safe and secure. At one point in my life I plugged everything in, and the amp Despite the fact that I have not yet tuned it to my stereo, I have already started the process. Despite its loudness and distortion-free sound, it was not disturbing. However, I hadn't yet found satisfaction with how it was tuned, so I began to tune it myself with the SMD DD - I. - Oh my gosh. I didn't realize how good this amp truly is until I was watching the video. There's no distortion, it's louder and everything sounds even better. A new level of definition has been brought to my ears by this amp. It is very easy to keep the amp cool, and that's one of the things I appreciate about the amp. This is the ideal solution since I like to play my music quite loudly. Yes, I agree. The amp might seem a bit pricy at first, but it is well worth the money. I thought it was a great amp to start with, and I highly recommend it. Please read carefully

It's a great amplifier
5/5

I was very pleased with the quality of the sound reproduction. The Pioneer DVD receiver head unit, paired with a full set of Polk Momo component speakers, is the ideal combination for my system. This system easily tuned in with only an Alpine monoblock audio amplifier, two Alpine type R12" bass speakers, and two Alpine type R12" treble speakers. The amp came with its specification sheet on the box, and it delivered almost twice as much power during the bench test as it was rated. If I decide to upgrade the system, this amp will certainly provide more than enough power. The thing I was looking for was more fidelity and clarity at a reasonable output level. I found this AMP to have a lot more in it than I thought I would need. I highly recommend it.

Another outstanding performance by Rockford
5/5

As of now, I am running this with 8 gauge wire and 4 channel monster RCAs connected to 2 component sets of Kenwood exelons, and it sounds fantastic. Even with only 45% of the CPU, I get loud, crisp You should be careful using it since it can easily make any door speaker perform beyond their limit (and beyond!).
