Question about Kenwood KAC-7202 Car Audio Amplifier

Kenwood kac-7202 wirng 4 subs

I have a kenwood kac 7202 and a pair of old 10" kicker comp (paper style...yeah old) and a pair of 12" fosgate punch.
i am running all 4 off one amp.
the first time i hooked them up i just ran a bridged wire straight to each speaker and it hit hard but the amp would get hot and after a while it would blow a fuse......either the one under the hood or on the amp.
now i have each set ran in a series (not all 4 together in a series) and bridged. it no longer gets hot but it doesnt hit as hard.
can i rewire in a different way and get the hard hit without overheating?
thanks for any help

    what exactly do you mean series-parallel?


    right now i have the kickers in series then bridged------and the fosgates in series and bridged.


    should i run them this way or should i run kickers to left and fosgates to right...unbridgede?
    my amp no longer gets hot but i dont want any future probs.


    thanks for the help mdscntst!

Look at the Z [impedance] specs for the amp. Look at the Z for the speakers. You may eventually have to wire them in a series-parallel config or risk blowing your output transistors.

Due to the utilization of so many drivers, your power demands are limited. The more drivers you utilize, the more volume loss. Bass response requires a lot of power (W) in which to drive.

Do not worry about paper or polyprop/carbonate structures... focus on your impedance issue or risk frying the output transistors in the long run [thermal runaway].

I have 2 10" Kicker Comp Subs


That amplifier is only rated at 150 watts at 4 ohms, or 300 watts at 2 ohms. Not a very strong amp to run 2 kicker comps. My guess is you have the subs wired wrong for your application. There are 2 types of subs, one is a dual 4 ohm, and one is a dual 2 ohm. Most people bridge these coils together and that cuts your ohms in half. For example. Lets say you have the 10cvr104 subs. Thats the dual 4 ohm sub. You wire the coils together in parallel, now its a 2 ohm sub. You have 2 of these subs running off of your amp, if they are hooked up in parallel, now you have a 1 ohm load, out of the amplifiers normal operation. Your amplifiers internals heat up really quick and there is a thermal overload, putting your amplifier into circuit protection mode. My suggestion for wiring your subs is as follows: for each speaker, wire the coils together like this- positive coil1 to negative coil 2 and negative coil 1 to positive coil 2. That is called running in series, and doubles your ohm load. Next, we need to wire the speakers together properly to hook up to your amplifier. For this, since the coils are hooked together, you only need to use one set of terminals from each sub. And take the positive from sub 1 and hook it to positive of amp. Take negative sub 1 and hook it to positive of sub 2. Take negative of sub 2 and hook it to negative of amp.

I a looking to qire two 10 inch kicker comps what is the best way to get sound out of this set up in a sealed box and kac 7252 amp 1000 watt


check the ohms on the subs if its single 2 ohm make sure you dont bridge it avoid 1 ohm unless the amp is class d duel 2s make 4 or 1 depending on if you series on paralel them duel 4s make 2 ohms or 8 you want to make a duel 4ohm 2ohm and put one on each chanel email me for better exp.

The subs aren't pushing out bass.


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.

Amp 4 a Kicker S17L7


just make sure your kenwood amp can at least handle a 2ohm stereo load.Most amps now are able to .Your amps manual should list this or go online and check for that model .You basically have 2 subs in one allowing you to use one sub box in stereo mode.And just hook it up like two speakers left and right ..make sure amp has a crossover so that you only get bass at your woofer

Hello smoot_dog,

Well, you did not specify whether you have the 2 ohm or the 4 ohm versions of the L7 and that will impact your choice of amps. But with 8 voice coils and 4 subs to work with, you certainly have lots or potential configurations.

If your subs are the 4-ohm version, I would recommend the Alpine MRP-M1000. Currently it is on sale at www.crutchfield.com for $347.00. With this amp you'd wire the voice coils in parallel (2 ohms), wire each of the 2 pair of subs in series (4 ohms), and the resulting pairs parallel to the amp for a final load of 2 ohms.

If your subs are the 2-ohm version, I would recommend the Rockford-Fosgate Punch P1000-1bd which is stable at 1 ohm. Crutchfield sells it for $349.99. With the Punch and 2-ohm voice coils, you'd series the voice coils (4 ohms), parallel each pair of subs (2 ohms), and then parallel the resulting pairs to the amp for a final load of 1 ohm.

Either of these amps will provide an honest 250 watts RMS to each L7. They'll not only rock your vehicle, they'll rock the pavement.

Off and On at mid and high volumes


sounds like you have a problem with your grounding on you amplifier. check for shorts on your amplifier and the place where you have it grounded. (or check the power wire also.)
