Review: Great amp for my highs! - What an incredible improvement! I installed a system in my commuter car (Ford Escape) and I was trying to stay on a budget. It soon became apparent that running my highs off my Kenwood Excelon head unit wasn't going to cut it, even with the built-in x-over. I have (2) 10" Infinity Reference subs in ported boxes powered by a Hifonics Brutus amp, and (4) Infinity Reference 4x6 coaxials in the doors. Off the head unit, the highs never really seemed to blend with the lows of the subs and there was some harshness that I couldn't get rid of. After installing this amp, the sound is just so much more rich and full - the harshness is gone, the tweeters sound smooth and crisp, and the vocals are enhanced. Everything seems to blend and is much more consistent at all volume settings. The amp stays cool and has enough power to get my Infinitys very loud. This amp was exactly what I needed and the price is very good for this level of quality.
Review: Rockford Fosgate R300X4 prime 4-channel amp - Great little amp. I installed it in a 2002 Jeep Wrangler about a month ago; it weren't no easy task but she's high and dry and out of the elements (top and doors off) and it turns my feet blue at night from the little blue LED power light. Road noise? I don't hear none anymore! I have it installed with a pioneer head and pioneer speakers in the dash and on the bar with a kenwood compact sub woof with amp under the driver seat... great sounding little setup and massages my back and butt at the same time! Without the fosgate amp hooked up i wasn't able to get above road noise (without doors) without a lot of distortion from the radio but with the amp connected this is no longer an issue; sounds are crisp and clear; running most music through a 2nd generation iPod touch. With the soft top and upper doors on makes the plastic windows crackle but this can easily be remedied by a little more volume and if the metal parts start acting up even a little more volume takes care of that, too. Even old country sounds sound new again. At any rate, ROCK ON!!!

## Questions & Answers

**Q: What are the dimensions of the amp?**
A: There's always some smart a** answer on here, like the other dude. That is the dimension of THE BOX it comes in. For the 300w one, the actual dimensions are:

13.2”x 6.8”x 2”
(33.5cm x 17.2cm x 5.1 cm)

**Q: I'm installing to a factory stereo with 4 aftermarket door speakers.  Will this AMP still require LOC's (line out converters)?**
A: You do not need an LOC , this amp accepts high level inputs . I have it on my factory head unit and it sounds amazing

**Q: Does the R300X4 have speaker level inputs?**
A: Yes it does its what I'm using and the sound is great

**Q: Would this power a Pioneer TS-A6995R 7 way speaker. I really do need as much sound as I can get. Can the tech guys break this down for me please**
A: Pioneer TS-A6995R 7 has a impedance of 4Ohm which doesn't cause much resistance. I believe the R300X4 could handle it. But if you still worry, you could consider R400 whivh is one notch higher.
