Question about Alpine Type-R SWR-1242D Car Subwoofer
Im looking to buy an alpine type r 12 and run it off a kenwood 9103d amp but im not sure if i should get the 2ohm or 4ohm version? i know this amp can put out 900rms at 1ohm and 500rms at 4ohms but sum people say it puts out 900rms at 2ohm aswel and im not sure so just need a professional opinion. thanks
If you get the 4ohm you can wire it to run a 2ohm an the kenwood amp will push 900 watts at 2ohms.they say it can push up to 1800 watts,that would be at 1ohm.that kenwood runs 500 at 4ohms an 900 at 2ohm.if you need help wiring the sub or anything else let me know [email protected],com Max Power Output 1800W Power Output 4 Ohm [14.4V] 500W x 1 [20-200Hz, 0.5%THD] 2 Ohm [14.4V] 900W x 1 [100Hz, 1.1%THD] Bridged[4 Ohm] -

Testimonial: "but wouldnt it just be better to get the 2ohm version of the sub then?"
Well, since an Alpine Type-R can only handle 500 RMS then you may want to stick with the 500 RMS range. I have seen an Alpine Type-R get SMOKED with around 800 RMS to it for around 4 and a half minutes. Here, take a look at a video of something similar to what I sawhttp://www.youtube.com/watch?v=rY8AfOdK4Y4), even though it is the 2-ohm version, the 4-ohm version will take the same amount before blowing. You are confused about the wiring issue, with ONE subwoofer, you can wire a 2-ohm sub down to 1-ohm parallel and up to 4-ohms series and with a 4-ohm sub you can wire down to 2-ohm parallel and 8-ohm series. What you will need to do is get the 2-ohm version(Alpine Type-R SWR-1222D) and wire that bad boy in series to get 4-ohm so you do not exceed the 500 RMS limit for the subwoofer.
