Review: Amazingly clean and powerful amp. - I just finished a large system build utilizing 2 of these beautiful power house amps minus front and rear door speaker installs. My stereo build was a ground up, interior gutting 4 day marathon and still didnt finish but will be revisiting and completing in a week at which time i will edit my review but i have enough info on this amp now to write a review. Heres my install: Pioneer Head Unit Audio Control LC7 (2) RF T400-4 (1) 1999 RF bd1000a1 (1) pair RF T1 5.252s (in rear doors) (1) pair RF T1652s (in rear deck of car) (1) pair RF T2 65 Components (front doors) (1) RF T1D212" (in custom sub enclosure) Electrical System: Optima Blue Top-quad post Big 3 0 AWG Upgrade 2 runs of 0 AWG to rear Kenetic Batteries (1) Kenetic HC 1800 Bat for sub amp (1) Kenetic HC 600 Bat for T400-4s I installed all electrical w/ RF products and tuned the entire system with a SMD DD-1 to set LC7 and amp gains to deck max volume before clipping. Once set it was time to play some music thru the 2 RF T652s in the rear deck of car & sub mounted in the trunk. WOW is the reaction i had when hearing how clear and crisp this system sounded for 3 speakers and stays that way the louder it gets. 1 T400-4 will run the rear deck & door speakers. The other T400-4 will be running the T265 Components in the front doors. This system will be loud and crystal clear, i wasnt sure this amps output was going to give my mids & highs enough power but the birthsheets show 73 watts x4 on both amps and it pushes these speaker nicely. Plus upgrading to a 800-4 or 1000-4 was way out of my price range, where this amps price here on desertcart is really affordable to most who love RF's Power series. Which is all i preffer to run in my system builds. A must buy for clean sure power on quality builds, easy to install and sure to keep you rockin as Rockford Fosgate has for over 30 yrs. UPDATE: I finished my stereo build and this amp is super clean & powerful on the RF T265 components i have it running. I spent about 12 hours breaking down the front door panels to clean and double dynomat before installing a new set of T265s and it was worth everyminute to do it right. The sound from them ia amazing and this amp is really clean at all volumes. The front channel is running my tweeters in HP, 5000hz @ 75 watts rms. And the rear channel the woofers in HP, 80hz @ 75 watts rms also. After the speakers break in i will fine tune the whole system and dial it in perfect. I have installed Punch series amps before and they are good amps but Power definately takes it to the next level. Way happy my whole system is based on the power series lineup. Keep rockin it RF!
Review: OMG...I'm speechless.... - Tiny amp, INSANE amount of POWER... I have built sound systems for many people and have heard many amps. I've tried JL Audio, Kicker, Phoenix Gold, HiFonics (and their other brands, Crunch, MB QUORT, AutoTek) and lesser brands like Power Acustik and Performance Teknique. Some of the amps I've tried are high powered to the point where I questioned their ability to provide clean and loud music while maintaing a low profile and keeping cool. My car is a 98 Cadillac Catera and I had taken off the stock Bose system out of my car and replaced them with Rockford's 6.5 Components all around. The amp that powered all this was an Alpine MPR-300. Don't get me wrong, the Alpine kicks ass for being such a small and powerful amp, but the Rockford Fosgate T400-4 just blew it in every way. First of all, installing it was easier than the Alpine. Everything feels worth the price with it's overall build quality. The terminals are probably one of the best I've used (unlike the JL 500/1 allen wrench style screws that become stripped over time). You need a screw driver and done. Nice and secure! Once I;ve had everything connected, the amp just screamed...I haven't even began to tune it yet to my stereo. It was loud and distortion free. I wasn't satisfied yet how it was tuned and then I began to tune it myself with the SMD DD-1. -OMG... This even scared me how good this amp truly is. Everything sounds even nicer, distortion free, louder. This amp really brings new definition to my ears. What I really like about the amp is the ability to keep it's cool. That's really the best since I like to play my music very loud. Yes...this amp is a little pricy, but it's well worth your money and I highly recommend this amp to anyone interested into getting a good amp to start off with. -Jose Morales YOUTUBE: Albinomexi

## Questions & Answers

**Q: Is that silvery product picture correct?  The description shows an entirely different product (which matches the manufacturer's website)**
A: This amp says T400-4 on the face. Although the amp that I had has a completely different look. I think this may be an older design of the RF amps. Power series are good amps and the only type I run... I have been running a Power 1050s since 2001. I don't even bother with Punch or even Prime series.

**Q: My HU has 2.5v preamp votage. Setting amp gain at 6 or above gives me audible hiss at any volume. The higher the more. What should I do to get louder?**
A: I had the same issue until I followed sonic electronix guide to Amp tuning. I followed the guide and the hissing stopped. Seems like I turned up the gain too much. At 75% volume on your HU, you shouldn't hear any hissing if no music is on or plugged in. In this case you tuned your amp correctly to your HU. To get it over with you can spend the money to have a professional do so, but I suggest you to follow up some guides on the internet. The sonicelectronix amp guide is a great guide for tuning your amp with your HU. Just Google guides and it will help you.

**Q: Can I hook this up to 3000 watts?**
A: No

**Q: How many amps does it need?**
A: Here is some information about the current draw of the T400-4

Recommended Fuse:  60 Amps
Average Current Draw (13.8V Music):  30 Amps
Max. Current Draw (13.8V Sinewave):  60 Amps
Suggested Alternator:  75 Amps

Thanks for your interest in Rockford Fosgate!

### ⭐ Not so hot......
*by K***7 on September 7, 2013*

I had high hopes and expectations for this amp.... I payed the crazy stupid amount for next day air (will not make that mistake again). It did come next day, but should not have spent the money for it. Anyway, I installed the amp per directions and it worked good, not great, for a week and a half. had to turn the gains up to about half way to get decent power and sound. in about a week and a half I lost 2 channels, 1 front and 1 rear. After troubleshooting with new RCA cables, speaker wire, and speakers, I narrowed it down to the amp. Back in my hayday Fosgate was a name to be reckoned with. Still may be, I may have gotten a lemon.... But this day and age, there shouldnt be any lemons when you spend 300 bucks for an amp. I dont know. I do know I will go back with pioneer or find a old school crossfire. They never let me down like Fosgate did today......
