Good enough amp for the $$

Good entry-level 5-channel amp. I have this behind my Pioneer AVIC-D3 head unit, driving Polk Audio DB691 fronts, DB651 rears and a pair of Rockford Fosgate P3SD412 subs. It's a great amp for this at 'normal' volumes, but doesn't have enough power to really drive the bass at really loud volumes. Overall, an excellent product. The only con is the size - it's kind of large.

Good amp

The amp is very good for a basic setup. the 300 w sub rms is limiting, but quality is solid. does not heat up, as others may mention.

Great sound quality!

I am impressed with the sound quality this amp produces when hooked to my Infinity 6.5" rear, 10" sub and 4x6" front speakers. Wow! I am sold on the quality of Infinity.

Great Amp

I bought this amp to replace 3 amps that I used in an active setup. The top end of this amp isnt as great, but the amps this replaced cost considerably more. Thank goodness that I have a 30 band EQ to smooth out the top end. The mid range and sub bass in this amp sounds the same. From what I can hear, this amp makes what it claims if not more.

I do not like the that fact that you cannot bypass the subsection in addition to supplied bass remote not working. Not a huge issue to me though.

The design of the amplifier isnt a strong point in my opinion. The large silver flange on the case is removable and the amplifier looks a bit better. Again, not big issue to me. The "Infinity" logo lights up a pleasant blue, not overly bright, very classy.

I have not had any issues with this amp yet. The amp stays fairly cool in the hatch of my car.

Overall, a great quality amplifier for the money.

Great Amp

I installed this amp, with 2 10" alpines, 2 6x9 alpines, 2 6.5 alpines comp, and 2 4' alpines my god it bonces my mini off the ground. Just make sure to use at least #4 monster cables to power and ground the unit and you will be very happy.

Nice Amp

This is a great amp for the money and does what u need it too. I am powering two 10" 400w rockford fosgates and they sound great in my F250 thanks to this amp. its also powering my two rear infinity 5/8" mids and the two front 5/8" infinity mids as well. the adjustable bass knob is a Great feature and comes with a supper long cord for hiding the control just about anywhere. i would buy this amp again if i need another one to do what im doing now. . . If i were u i would buy it!!!
