Sub question
 

I am a total noob at audio stuff....but I like how its sounds so....its a learning process...haha

I have a question about types of subs....

I'm running a Kenwood KAC 929 amp....which is 1000W max and i think 400W rms....

Whats the difference between 2-ohm and 4 -ohm subs? and which one should i be getting for this amp?

I currently have 2 12" earthquake subs in my car but I have no idea what kind of ohm they are.....one blew recently and I'm looking to replace it....want to get the right sub kind....

thanks

That amp is rated 460 watts x 1 into 4 ohms, so what you need is two 2 ohm subs in series, for a 4 ohm load. They'd each get 230 w.
OR, one 4 ohm sub that will take all 460 w.

According to Kenwoods website that amp is rated as follows.

150w x 2 @ 4 Ohms

or bridged
460w x 1 @ 4 Ohms

It does not appear to be stable @ 2 Ohms when bridged.

So you either need two single voice coil 2 Ohm subs wired in series @ 4 Ohms

or

Two dual voice coil 4 Ohm subs wired @ 4 Ohms.

This is assuming you want to keep 2 subs.

Hope that helps.

Looks like I took to long writing that last post. You beat me to it Tom !!!

:)

thanks for the replies guys......

so just to clarify...what rms subs of each type can I get

2 ohm 300 W rms single coil?

and 4 ohm 500W double coil?

is that right?

BUMP!....

anyone that can answer the above question....

You need a 4 ohm load and you'll get 460 watts RMS.

2, 2 ohm subs 250 w rms each.
0r
2, 4 ohm dvc, 250 w rms ech.
Or
1, 2 ohm dvc, 500 rms
Or
1, 4 ohm

Hey guys,

A followup here.....I have been looking around at suitable choices very carefully......

so far there seems to be a concensus from audio shops that Clarion is a bad brand to go with...lol

So my question is......with my amp, is 2 Alpine type S's (SWS-1222D) the right subs for me?

they are dual voice....but they are 2-ohm....would this be compatible coz thats what one audio shop recommended.

Who says Clarion is bad?? A shop that does not carry them. They perform better then most and just as good as a pioneer, Kenwood ect. With that amp just get one PXW1051 or PXW1251 for under $150 taxes in and you will be all good.

/\ ...what he said....:smilie_da

Clarion doesn't aim for the SPL records....their stuff will get loud enough to damage your hearing while still sounding good.

From what I've seen, they are heading into the in-car entertainment scene in a big way....it takes a pretty decent quality system to go for THX certification and that includes bass.
