I was thinking now of getting 2 kenwood 12 inch 4 ohm single voice coil subs and wondering what watt amp i need http://www.bestbuy.com/site/ol...etail

That is the specs on the watt for the subs,now my question is if i want one amp what do i have to get? http://www.bestbuy.com/site/ol...88120 would that work?

 

You have two 400W continuous 4 ohm subs, you should be looking for an amp that will make at least 1x800W RMS into a 2 ohm load, [two 4 ohm subs wired in parallel is a 2 ohm load], a 1X1000W RMS into a 2 ohm load amp would be better, as it is better to be overpowered then underpowered.

The amp you link is not powerful enough to drive just one of your speakers properly.

The way I read the specs it will make 1x220W RMS into a 4 ohm load, [one sub] just over 50% of what one of your subs need.

It is unlikely the amp is stable at 2 ohms when bridged, so the only option would be to leave the amp is 2ch mode and wire one sub to each channel, the amp would make about 2x110W RMS into a 4 ohm load, it is the wrong amp to drive those subs.

Again, look for an amp that will make at least 1x800W RMS into a 2 ohm load.
Look for a mono block sub amp.

This is an example of a 1x1000W mono block sub amp... http://mobile.jlaudio.com/prod...d=440 probably out of your price range. 94

 

Wow confusing lol I found this though better? http://www.crutchfield.com/App...C81W3

 

Better, but still underpowered, assuming they are 400W continuous subs.

Please do not misunderstand, there is no problem driving two 400W 4 ohm subs with a 1x500W RMS into 2 ohms amp, it will make sub bass, and if the box is properly built and to spec, it will make pretty good sub bass, however, you will not be able to drive the subs to their "full" potential, you will have a 500W sub system, not an 800W sub system.

The most common sub bass "failure" is burnt VCs, [voice coils].
Underpowered amps driven into constant clipping because the user "cranked up the bass" a clipping amp produces DC current to the speakers VCs, heating them up, until they get hot enough to burn, kind of like plugging in your lighter.

Even though the reverse is also true, driving two 400W subs with 1000W will burn the VCs just as fast, but music is dynamic and the amp will hardly ever make 1000W, and when it does it will only be for a slit sec. or so, [this is where the speakers max power means anything] the average output of the amp, even when "cranked" will be less then the subs 800W total continuous power handling with "peaks" less then the subs max power handling, [1600W].

So it does come down to the guy that controls the the subs level, if you can keep from driving the amp into constant clipping, the above linked system will work, so would the first one for that matter, if your a bass head and you can not control the urge to crank up the bass you will burn out the subs in no time. 94

 

Wow lol thanks very imformative, yes i am a bass head lol. I guess the best bet is to get the subs and get a higher amp thanks.

 

Got the sub today it is a Pioneer TS-W300R and a 250 watt bazooka amp. This is my first system and i dont want something very powerful just something that bumps a little. Would this sound good? Also it came with the wiring would this be able to work on my car seeing how it came out of an s10? And if i want to upgrade later can i use the same wiring and just remove the amp and sub and hook up the new on to the wires?

 

Would 250 watts be good to push 1 of these?

 

What gauge is the wire kit?
What is the subs continuous. [RMS] power handling?
What Bazooka amp? 94

 

4 gauge i think http://www.audiodiscounters.co...W300R is the sub and http://sfbay.craigslist.org/eby/ele/568629896.html is the amp

Here are the pics can u check if all the wires are good

OIC, you have two 12" 150W 4 ohm subs.

That makes the Bazooka amp underpowered for even one of the subs, amp is 1x100W RMS into 4 ohm, with both subs, wired in parallel, the amp will make 1x150W RMS into 2 ohms.

You need to look for an amp that is 1x300W RMS into 2 ohms. 94

 

Nope just one sub
