All I did was swap the power, ground, remote, and speaker wires over from the cheap amp to this one and turned the stereo on. So, I find this KAC-8405, which had a similar power rating to the "cheap" amp (Crutchfield private label Sound Ordnance). The sound was hollow, and un-natural sounding. First and foremost, I initially purchased an offbrand amp looking to save a few dollars. This review is from: Kenwood Kac-8405 720-Watt 4/3/2-Channel Amplifier with Variable LPF/HPF (Electronics) If you're looking for a basic system, this amp IS the solution. I started with the gain's set to 4 to match the receivers input, broke in the new speakers and then starting increasing it "1" unit at a time. I error on the high side and used the receivers cross over feature to complete the set up. You have to "guess" where 100 is, due to the size of the slot for the screw driver. The cross over filters are nice but could use better markings to accurately set them. I used a 4 awg wiring kit, needed to grind a little off of the sides of the amp wiring kit terminals to get it to fit into the amps screw, no big deal.Īt really low volume you can hear the cooling fans running, barely. The foot print of this amp is almost equal to a 8x10 sheet of paper. It installed cleanly under the front seat with plenty of clearance. This review is from: Kenwood Kac-8405 720-Watt 4/3/2-Channel Amplifier with Variable LPF/HPF (Electronics) I installed this amp in a 2 door 2010 Tundra to power Infinity 630's and used the second channel, bridged, to power a 8" Infinity sub woofer.

The amp was easy to install (I mounted the amp to a 3/8" plywood panel. As good as the speakers were, they are now that much better. I don't listen to the radio any louder than before but everything sounds much fuller and well rounded. I had read that an amp really makes speakers sound much better, I was not expecting it to. The speakers made a world of difference but I was concerned about blowing the radio out due to the 2ohm speakers so I figured it would be better to put in an amp to avoid that possibility. I upgraded the speakers with Infinity Kappa 60.9CS up front and Infinity Kappa 63.9's in the back.

I just want better sound quality from my factory stereo. I'm a 40ish male not looking for thumping music nor music loud enough to make my ears bleed. I can't overemphasize how happy I am with this product. This review is from: Kenwood Kac-8405 720-Watt 4/3/2-Channel Amplifier with Variable LPF/HPF (Electronics) I installed this into a 2011 Hyundai Santa Fe directly from the base factory radio.
