Two amp i had a kenwood km-895 power amp hooked up driving my two 12"subs,and now i have peavey cs-1200 hooked up driving the same two 12"subs,but the kenwood amp pounds the subs harder with less power... i have kenwood runing a 8ohm,,,peavey running at 2ohms my receiver is a harman kardon avr-630 please help Brad

You have the ohm load at 1 your amp i

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.

Did you google for the specs? Gotta be there. Meanwhile the amp will drive your speakers - the issue is if the amp has enough power to drive the speakers to the volume level you want without distortion. Whatever you decide be careful with speaker wiring and do not hook them up in parallel lest you want to toast your amp stages to a crisp.

speakers are rated at 4800 Watts "program"... for safety, I would use an amp that can deliver around 1200 Watts RMS.

Hi, ensure amp has 12v on the "+" and "rem" terminals and has a good ground to the amp, This is all the amps needs to start up

you can run 2 subs given that you dont go over 2 ohms of resistance and that the subs are rated at 1000 watt max each around 4 or 500 watt rms. if your not sure about ohms dont bridge it and get single voice coil subs. this amp is capable of about 700watts constant power 1200 max spike if the voltage stays at 12 or higher.

Line outs Left and Right from mixer to power amp Left and Right inputs,
Power amp outs to Subs(if they have passive crossovers built in check specs on subs).
From Subs then to Main spkrs. Make sure power amp is set in stereo mode using this way.

Alternative: You will need at least a 2-way stereo crossover unit inline after mixer and before power amps if the subs don't have a built in passive crossover. Most of them do have passive crossovers in the subs these days. Then separate amps or one channel would drive the subs and the other the main speakers. True stereo would require at least a 2 way crossover and two stereo power amps if hooking them up this way.

There is another option as is common with many sub setups. Send the signal to the mains using L/R outputs from mixer and a separate Mono output to the subs only. Putting only bass/kick and low frequency outputs in this send would help too.

Hello crobins2,

The Kenwood KAC-6202 2-channel is only rated for 60 watts RMS per channel into a 4 ohm load. That just isn't much power for a pair of 12" subs. Even the bridged output is only 200 watts into 4 ohms, still at the low end for a sub, much less to share between a pair of subs.

Assuming that your subs are 4 ohm, you could probably get more sound by driving just one of them on the bridged terminals. But to get the best power with what you have, connect one sub to each channel, set the filter switch to the far right (LPF), set the operation switch to stereo (both channels driven), set the filter frequency (Hz) to 100 or lower, and adjust the input sensitivity as far clockwise as possible without causing distortion.

But, to do the subs justice, you really need at least 300-400 watts to share between them.

Hope this helps.

If you are trying to use 3 amps to drive a single cabinet, it can not be done. Bridging amplifiers requires a specific circuit design for that application. There is no way to hook up multiple amps to a single speaker.

check your fuse up front first. some amps will turn the light on with only the remote wire (the 12 volt signal from the head unit). That may be your issue. If not you need to check your signal input. try hooking the rca's to a diffrent source, i.e. other radio your tv anything with Rca out put. If still you get nothing then pull your subs out and take a regular 9 volt battery and touch the leads to the positive and negative of the sub. Just for a moment though if the subs move when they come in contact with the charge from the battery then my last suggestion would be to take it to a store where you can have an authorized tech check out the equiptment. Good luck
