Great value

Fast shipping works great with no problems. I would order other if i ever needed it

Ok starter Kit

It's a ok kit to buy but check the RCA jacks my kit came defective one pair of RCA jacks failed. When I finished completely installing it in my truck and turned on the head unit only to fine out 3 of my 4 channel amp was working had to take out the multimeter tested the Amp then uninstall all the head unit tested RCA jacks and one pair was defective I would assume that they would work they are New. So save time and test the RCA jacks for continuity.

Good Value Kit!

Everything I needed and good quality wire, not like some other cheap thin gauge wire you get in similarly priced kits elsewhere.

Everything needed for a 4 ch amp install. Better quality than other cca kits I have used before. Nice thick strands.

Awesome Buy

It was everything I needed one package for a great price

Works as said

Works good and is high quality cca wiring, better than many others I have used. Fine for about a 400 watt rms 4 ch amp set up. Larger go with 4ga to be safe.

Pretty Good for the Price

Overall, the amp is super solid and seems to be built rather well. Having a rated power certificate in the box was also helpful to see that it actually is putting out the claimed RMS power or above. Currently using it to power a single CompR 12" and it hits hard with the gain barely over 1/3 and no bass boost. Only complaint is that the power and ground inputs are not designed for bare wire, you'll need to buy a U or spade connector to reliably attach your power and ground.

Good value

Good value. All the stuff you need for a couple of speakers and a sub to an amp. Easier than buying it individually.

Small and powerful

This amp is great. I have it mounted behind the backseat and it takes no room at all. It's got pre-amp and output RCA connections so I have my stereo amp getting signal. You can only use fork terminals with the connections but the connections are solid. Unlike some amps. Two speaker outputs for easier wiring if you are using 1ohm which I have two 10" Kicker DVC 4 ohm subs running at. Overall 5 out of 5 would buy again.

Great transaction

Fast transaction fast shipping love doing business with Sonic Electronix

Great transaction

Shipped from the manufacturer in a timely manner, took 3 days instead of the proposed 2 day guarantee, but overall still a great transaction.

Under rated quality amp for the price

This cx 400 is amazing! On the higher end of resistance its minimal, push a c10 or c12 but bump it down and let it go to work. 2 c10's at 300 at 2 ohm, you'll feel it knock, drop it to 1 ohm, good god, I set the sensitivity to run 500 rms, per the rated rms of 533w on kickers birth certificate, this little guy moves single p3d2-12, pounding so hard my rear view mirror shakes to the point you can it rattling the windshield. I recommend this to anyone who wants a lower total rms output or a bi-amp system (given youb match up your impedance and wattage (rms) of chosen sub. I messed up my original purchase, got a JL 12W0 crank it up and live loud

Kicker amp

This is my first kicker amp and love this product and was easy to hook up. I have had other amps and wasn't satisfied on how you had to hook the amp up because the controls you had to use an Allen wrench to loosen or tighten the controls. Kickers product a flat head or a Phillips screwdriver will work on their amps to hook it up and made it easy and fast to hook up! I would recommend this product to anyone else for a small amp that just brings the power to your subwoofer!

Amp installation kit

Belva did a great job with this 4 channel amp wiring kit. Had more than enough lengths on all wires. Terminals are solid. Will buy this kit for now on for my 4 channel amp installs.

Nice Kit

Worked great in my 1997 Tahoe. Had enough cable to put the amp under the passenger seat. If you're trying to put it in the cargo area, you'll need more cable.

Very good value

Everything I needed was included in this kit to install my Amp.

The connection

Very well made nice package wow come with mostly everything you need great value for wires and amp

Good for small cheap builds

Not a top tier brand but gets the job done for my garage builds. I don't trust it for major builds but not bad of a product
