Question: Would this amp be great for polk db components up front and polk db caxials in the rear?
Document: Excellent amp, great price! What's not to love? Front two are going to Alpine Type R 6.5&#34; Components, rear are bridged to a 10&#34; Pioneer TS-SW2501S4. Factory sheet showed 521W, and I'm super happy with the purchase about 2 months after installation.
For the price.. The quality you get in this amp is not beatable. Very sturdy product, have this guy powering two kicker 11KS60 in the rear, and two alpine components in the front. If you have never experienced amplified sound, this will impress you very much. RF stands for quality, they have never disappointed me, and they wont disappoint you.
Ive been running Fosgate amps since the late 80s and have never been disappointed. The sound great run cool and never have failed me. Using this unit in a 04 Mustang Gt Vert, replacing the factory MACH 460 system amps. This runs my front four polk component system speakers, with a second amp bridged mono running a Sub box in the trunk. The adjustability and output was perfect for my needs. price point was good too.
Purchased this amp for my 2003 chevy Silverado extended cab pickup, have it running two 6.5&#34; jbl's in the front and two 4x6 Rockford fosgate punch's in the rear and it sounds amazing. Highly recommend this little amp.
(2)  The front speakers sounded horrible! I have Infinity component speakers in the front with it's own crossovers and there was a lot of distortion even at low levels. Sometimes, the sound in the front will cut from good to muffled over and over. So, I set the X-Over switch on the amp for the front speakers to HP. And now it works great!
Low gain, for instance, is preferable to high. My front gain is set to about half-max. Freq. set to just passed half. If I had to guess, I'd say around a hundred hertz. The infinity's get pretty low w/o distortion. I have the amp in 4 channel mode because of the sub, otherwise. The rear channel, bridged into 4 ohms puts out about 200 watts according to specs.
Today, I put a voltmeter to the channels to see if it was putting anything out to the rear. I cranked up the volume to instigate the problem, and lost my front/right Focal. So it's not the speakers. I went to check onboard fuses, and the amp doesn't even have any!I appreciate that Rockford wanted to cut corners to make this amp more affordable, but it looks like they went too cheap this time.ps- my build sheet said this amp put on 533 watts.
I did use the speaker wires and radio ground wire from the harness and ran new power and remote wires. 8ft rca cables from the receiver to the amp. The amps front channel powers a set of infinity kappa 6.5" door speakers rated at 220watts peak. The rear channel is bridged and powers a quality 10" flat subwoofer rated at 800watts peak. The sound is amazing! If you take the time to learn what the amp settings are and how they are to be used.
I had it higher at first but it was overpowering. The frequency is set just below a hundred hertz or just about where the front channel leaves off. It's a beautiful blend. The punch-eq is set to close to half and provides plenty punch for me. It's all working great together. I feel that I have more than enough volume. I have no distortion at tolerable volumes. The amp gets warm but not hot. I used 10 gauge power and ground wires. The ground is clean and solid.
I hooked this up to a pair of Focal 165's (60 watts RMS) on the front channels (no gain) and an old pair of Infinity Kappa 3-ways (111 watts RMS) on the rears (+2 gain I think). I was enjoying things on a 1-hr trip that first night, and halfway in, the rear speakers started cutting out.
Answer: mine burnt out in 2 months,amazon would not warranty it...I would not buy it from them
