new spakers questions

[busafreak]

So I purchased some new speakers to replace the stock tired speakers. I purchased 2 Kenwood 2way 4x10's and 2 kenwood 2way 6.5's for the doors (its a 2 door)
Im one that doesnt listen to much music, I'd rather listen to the engine. So its safe to say I dont know anything audio. But I do know that I have nothing but mids and highs when I do listen to music. So I purchased a kenwood mono amp and 2 10" subs to put in the back. Im not trying for great sounds obviously, I just want something ok for when I do wanna hear music.
So how do i wire up the amp to the subs? I know how, but theres talk about ohms and impedance(sp?) And overheating and such. Can someone help? Is 4 2 way speakers and the stock tweeters hooked up a stupid idea? I dunno..

Post details on what you bought for some detailed help.

The 4x10's, the 6.5's, and the amp I purchased new. The subs are obviously used but they work and the box has mdf seperating both subs (if that helps any)

great choice on amp but it can overpower your subs even if you wire them in parralel which is what I reccomend. The sub appear to be specified for a free air enclosure which will not work correctly in a sealed enclusure which you claim to have. Might I recommend this:

http://www.crutchfield.com/p_113W2513PS/Kenwood-KFC-W2513PS.html?tp=111&nvpair=FFBrand|Kenwood

Right now two would cost you $140.

would solve your enclosure and power capacity problems and would be good in a free air or sealed box.

At any rate the sub woofer setup will certainly out power your speakers. What are you driving the speakers with, head unit?

 

[busafreak]

Good point.. Thats a good price for two and I like that its all Kenwood.. I think ill get me a pair.. Currently I have a kenwood kdc mpv622h3 head unit with a kenwood cable thats hooked up to the cd changer plug that I use to hear music from my Evo phone. It has front and rear rca outputs. I also have another Kenwood head unit that I purchased from crutchfield when I got the speakers, but dont have the model # currently. Parallel hook up huh? Ill look that up. Thanks a bunch for your help..

 

[SunlitComet]

if the subs are single coil 4 ohms each and your sub amp can handle a 2 ohm load then parallel is best.

Also perhaps you can pick up a 4-channel 40w rms per to drive those speakers.

 

[busafreak]

Amp says can handle 4ohm.. So you are saying I can get a small 4channel also to bump power to the other 4? So I would use the front rcas for that and run new speaker wires to the four, right? You are a great help man, thanks!

 

[SunlitComet]

Something like that. Use your preouts for a 4-channel amp to boost your speakers and use some Y - splitter cables to split the front to also go to the sub amp. Your sub amp can handle a 2-ohm load. Is that the one you were talking about or were you mentioning a 4 -channel amp handling 4 ohms? Just want to clarify. Would recommend 16 guage wire for speakers and 12 for subs BTW.

 

[busafreak]

Oh, I get what you are saying.. I would run the rcas to run the 4 channel and then use splitters to run the sub amp. Interesting.. Hey Im learning something... Oh man, this is a start of an addiction isnt it? Lol... No, I thought the Kenwood sub amp that I have had a 4ohm capacity.

actually at that rating the new subs could be over powered too if you push it far enough. How about one sub in a new box hooked directly to sub amp for 300w continuous? Since you already have the sub amp they would mingle well.

or just leave one sub enclosure opening unused.

It will get very addictive being here

i didnt read the specs on all this, but depending on how much its overpowering by, if he sets his gains conservatively, he shouldnt have too much of an issue, looking at the last post of running 1 at 300, my guess is these are either 250wrms or 200wrms woofers?

even so, conservitive gain setting and making sure you arent clipping should be alright overpowering

and also, you shouldnt expect to see the full power being that that kenwood amp is a class d mono, meaning its digital and after box rise and everything the ohm load will sit higher than theoretical 2 ohms

just my 2 cents on not reading thru the speaker specs, lol
