My 800 watt kenwood

I have a bridgeable 2 channel 800 watt kenwood amp. just recently my inline fuse on my power wire melted i think the wires may have touched. i put a whole new fuse unit in and the light on the amp doesnt turn on so im wondering if that may have blew the amp or if it is fixable

Sounds like you shorted out the main power wire somewhere and killed the amp. Is the amp on the fuse intact or blown? Do you have 12 volts at the amp? check you connections and see if it helps.

My legacy la 4299 amp power is on with the car off


there is a remote on-off power wire that is supposed to connect the amp to an internal circult, which only sends power when the car is on. you can tap this kead off the acc fuse, but the actual power needs to be ran directly to the battery, with an inline fuse under the hood

I have 2 12in kenwoods and a 1200 watt pyrimade amp, how can i hook these up to be the loudest


1st have your subs facing inwards towards the front of the car, not facing out the boot, This creates a better bass.

Wire 1 sub to one channel and the other sub to the other channel.

Turn down your gain as low as possible and then power everything up.

turn volume to desired loudness and then start turning up the gain slowly, if distorts a little turn in back down a notch.

avoid using bass boost, I agree it sounds great but it puts more strain on your amp and shortens its life.

after sorting out your gain, tweak all others until sound is bassy and clear with no distortion.

If you would like to use bass boost, turn on bass boost first, then up your gain etc.

I dont no how many watt my amp has


Hi and welcome to FixYa,

To my understanding, a Kenwood KAC-628 is rated with max power of 100 watts X 2 at 4 ohms per channel. Incidentally, it is bridgeable resulting to 300watts X 1.

Good luck and thank you for asking FixYa.

I got a 4 gauge power wire w a 20 amp fuse hooked up to a kenwood stereo/bridgeable amp 350 watts max power model #kac~6295 it just dnt sound rite any sugestions?


make sure you run your power and ground wires opposite of the rca/speaker wires. you tend to pick up alternator noise when all wires are bunched up together. Also, make sure you have a good chasis ground to the amp, and the stereo has also a good ground. good luck

Amplifier loads


Hello ronnieyannon,
A single 4 ohm speaker wired to each channel, like you have them wired, presents a 4 ohm load. And it appears that you have them connected properly. The 401s is only stable to 4 ohms when bridged, so if you were to parallel the 2 4 ohm subs in bridged mode, the load would be 2 ohms and the amp would most likely overheat and go into protection.

I'd wire them the way you have them wired.

Each channel of the amp outputs only 100 watts into 4 ohms. That is adequate for regular full-range speakers, component speakers, mid-range drivers, and even some small subs. But it is a little low on power for most subwoofer applications.

Hope this helps.

Speaker amplifier calculation


for $85 i can sell you an Almani 900 watt 2 channel amp i would stay way away from those 3 brands they are all really poor quality and i can get you any major name brand cheaper.
I can get you a hifonics 4008 amp (800 watts peak 100 watts per channel rms) for $100 shipped with full factory warranty. you find an amp you like and i will get you a price. I am a factory wholesale distributor for most brands.

Is it not bridgable


This amp isn't bridgeable. It's a mono amp (only one channel). You need two independent channels to bridge. Some mono amps are bridgeable if you have two identical amps but I don't think Kenwood recommends that with this amp.

Swap the wires from one speaker to the other to see if it is the speaker or the Amp/wires.

The remote turn-on wire for an amplifier connects to a switched power source. If the head unit has a power antenna lead, or amp control lead, use it. If not, the remote lead can go to a power source that is switched with the ignition key. No matter the source, you need to fuse the wire with a 1 amp fuse at the point where you connect to the power source.
