Engine noise from Legacy 4000W 2 channel amp

Dear Sir,

I have installed a Legacy 4000W 2 channel amp to power one 12in dual coil Kicker sub speaker and I am getting " engine noise " and the power is not enough for the speaker. I have experimented with wiring it both parellel and series with no great performance.

Any assistance is appreciated.
Justin

Hi Justin,
Send me the specs. on the speaker ( voice coil impedance), amp, power wire size, and box
As for engine noise ( alternator whine) 99.9 times out of a hundred it's caused by what's called a ground loop, That will take a little trouble shooting on your part. It's no big deal. It will be a step by step process. All you need is two alligator clips or a old RCA cable.and a couple feet of wire. I'll try to get to it this evening,
Oh, and you will have to pull the head unit out of the dash... P

How do i wire my kicker dcvr122 up to a 4 ohm amp


I am going to assume the 2 speakers in the sub are each 4 ohm loads, and are wired together in parallel, creating a 2 ohm load. And your amp pushes 800W at a 2 ohm load. And actually goes down to 1 ohm/1100W. Anyway...

Seems you want to lessen the wattage output of the amp by making a 4 ohm load. To do that, you need to wire the both 2 ohm speakers in SERIES.
In general wiring principles, to wire in SERIES, take the POS terminal from the amp and wire to the POS terminal of first speaker. Take the NEG terminal from the amp and wire to the 2nd speakers' NEG terminal. Then place a "jumper" piece of speaker wire to connect 1st speakers' NEG terminal to 2nd speakers' POS terminal. Now you have a 4 ohm load, and will be pushing 450W from your amp.

This way the load will now be 4 ohms.

How to connect dual vouice coil to amp


Hey well your gonna need to give more info. is the sub dual 2ohm dual 4ohm. if you have a dual 2 ohm you wire one + to one- (like a jumper wire)and then your other +.- go to your amp as 4ohms, if you have a dual 4ohm model and your amp can handel 2ohm stereo then wire your +to+ to +on the amp and the same for your -. it will bring a 4ohms to 2 ohms by connecting pos. to pos. and neg.to neg. then to your amp.

Kickers shut off


Has nothing to do with the sub's . This is an AMP problem. Best guess is you are running at too low of an impedance. Most likely (sight unseen) you are running a 2ch AMP @ 2 ohms bridged, or if the sub's Dual voice coil you are @ 1 ohm, and most amps frown on that.

Give me some specs..

Amp make, and model.
And EXACT model # of the sub's. Give me this info, and I will tell you how to make it work.

Pioneer deck kicker sub 2 mossfit amps


scanman84: i would recommend using the 2 channel 300W amp to drive the dual voice coil alone. i wouldn't combine the single channel amp with the 2 channel. you can't tie the 2 channel outputs together & use that on 1 voice & attach the single channel amp to the other, plus there could be slight differences in amplification & timing which, could cause the sub to have minimal movement or cause a canceling effect which would reduce the spl, sound pressure level. if you need more volume use the lowest impedence speaker recommended by the amp's mfg & if you need serious volume, go with a higher output single 2 channel amp. just make sure you have sufficient wire size to handle high powered amps. example, 8awg wire is rated for 73 amps. also make sure the amp is well grounded with nut & bolt connections to the frame & that there is good ventilation.

peace-out

How to wire kenwood amp to kicker cvr 12"


How you wire it depends on how hard you want drive your amp. If your woofer runs 4ohm per coil I would wile it in series (amp +to sub +1 sub -1to sub +2 amp - to sub -2) then run it for a week and see if it has enough power. the lower your Impedance (the resistance load on the amp) the harder your amp works and more THD (noise) is produced. (Dclass amps aren't know for being clean to begin with) configured like this your amp will see 8ohms and sound the clean east. if this turns out to be not enough power wire it in parallel and double the output. wire amp + to sub +1 and +2 then amp - to sub -1 and -2.

A word to the wise... start with your volume very low and work up slowly most speakers will puk up the voice coil before the amp starts to get warmed up. you would hate to have to buy a new sub.

Have fun

Wiring my kicker solo-baric 15's


The best you can do is connect the dual 2 ohm voice coils of each respective sub in series (4 ohms total per sub) and then connect each sub to one channel of the amp. This will give each sub 1000W, which is the rated maximum from Kicker.
