sub and amp help

[dreVanHalen]

Hey guys,

I am in the process of installing my system and had a quick question about setting up the amp. I am running 2 jl 10w0's from a kenwood 600w sereo/bridgeable amp. I just need to find out if I leave the amp in sereo and run wire from each channel to each amp? or do i flip it to mono and bridge it and run wire from the same spot on the amp to each sub. thanks for any help guys.

I hink you really need to read the manual for the amp.

All the Stereo/mono switch does is combine the signals (mono) or keep them seperate (stereo).
How you wire the speakers is what matters, check out the12volt.com for detailed wiring instructions.
There is a calculator there to help you maximize amp output.

I know what the difference between mono and stereo is. I am by no means a noob to music/sound or car audio. I just have never installed dual subs and need to make sure this will work. you really contradict yourself by telling me to go and read a manual, then giving me a website to get my answer on. I understand the wiring is what makes the difference and if you read my question that is what I was asking is how to wire it. I appreciate your response but if someone else could please chime in it would be greatly appreciated.

I don't see how reading a manual will help me with this question. All amps as far as wiring go are going to be the same. generally bridged will get you the highest power output to use the amp with a sub. The only thing I need to know is can you run 2 different subs from one output/channel on the amp. In theory I don't see why this should be a problem because both subs would be getting the same signal at the same power. I just need reassurance from someone telling me this will or will not work.

What model # is the kenwood amp?

Most kenwood stereo amps won't do 2ohm bridged so you will have to run it in 4ohm stereo.

[dreVanHalen]

it is a kenwood kac-7285 600 watt amp. If I remember correctly my 10w0s are rated at 4 ohms. I got the subs and amp from my brother who ended up not using them, and of course now he can't really remember the correct setup. Will I be losing power by having them not bridged?

[dreVanHalen]

looking in the manual it says that bridged the connections will be 600w at 4 ohms and my subs are rated at 600w peak at 4 ohms. So if I bridge the amp it should be putting out the correct power. If I do it that way, should I wire the 2 subs in series or should I wire them in parallel. From my understanding though, running them in series would drop the impedance to 8ohms am I correct?

Since your amp is not 1ohm stable (stereo), it will not support a 2ohm bridged load (your subs in parallel). Therefore, you need to either wire them in stereo @ 4ohm each, or wire them in series with the amplifier bridged...either way, you're effectively using only 1/2 the available amplifier power.

either get a different amp, or get different subs...

so to run parallel the amp would have to put out 2ohms in order to get the 600w at 4 ohms?

no, when wiring your specific subs in parallel, you're presenting a 2ohm load to the amp on a single channel (bridged). The amp will not be stable under that load, and most likely go into protect/overheat, and you'll have very little dynamic headroom...

for you to "get the 600w at 4ohms", you need a sub/coil combination that equates to a 4ohm load...as you're amp is rated at 600w @ 4ohm mono.

[dreVanHalen]

so to get the most out of the subs I am looking for an amp that will put out 600w at 2ohms? would something like this work out??

[koolade9]

That would work better for your topology. Another avenue would be getting a different sub or subs that could present a 4ohm total load.

Thanks man. I really appreciate your help. Thinking I will just run from stereo for now as I'm broke and then eventually buy a different amp as that will probably be a bit cheaper than new subs. Thanks again
