8 Ohm or 4 Ohm?
I am thinking about replacing the 8" sub in my 2002 SC430 and was considering putting in the JL Audio 8W0 and JL e1200 amp to run it.
Specs on the e1200:
120 W RMS x 1 @ 4 ohm
200 W RMS x 1 @ 2 ohm
The stock sub is 12 Ohms. My question is, should I get the 8 ohm or 4 ohm 8W0? Sound quality is the most important. I just want a little more bass and don't need to rattle windows. The audio salesperson said go with the 4ohm because the amp is designed to run 4ohms. What do you guys think? Any help is highly appreciated.

I don't know where you are getting your figures from but they are incorrect. Again, most amps are designed to run around 1 to 4 ohms. Most amps put out the most power on the lower end of that range due to the decreased resistance. At 8 to 12 ohms, that amp would put out 40 to 80 watts RMS for about 10 minutes before it fried it's circuits from the resistance.

I don't know of any car audio amplifiers that aren't stable to 4 ohms bridged. Get the 4 ohm model and use all of the power you can.

The e1200 is easily stable down to 2 ohms and prob 1.5 !!!
Get a 4 ohm driver. The 8 is made for parallelling multiple subs and ending up with a 2 or 4 ohm total load, depending on how many you have and how they're wired.
For pete's sake, don't get an 8W0 if you're concerned about sound quality. The whole W0 series is horrible (according to me, sorry...) for sound quality - if that's what's important to you. Every single time I've heard them I've almost puked, I literally can't stay in the same room with them running. They are underdamped and flop like a fish out of water when stimulated. I've watched the 10's and 12's do their thing and the 8 can't be much different. There has to be something better you can put in there. I hate to beat up on JL 'cause I like most of their products, but the W0 series...
Though I haven't heard it in particular, the 8" W3v2 should be a better choice if you can fit it in (watch out for depth and room for excursion). Is there really only an 8" sub in the SC430? Can you squeeze a 10" in there? (10" W6v2 ?) That would open up much better choices.

Muh Bad Buddy. I responded while half asleep and did not notice there was an aftermarket amp in the picture, my comments only reflect factory systems. (yawn)

Thanks for the insight guys. I chose the 8w0 because some of the SC guys have replaced the factory sub with the JL and have had great results. Again thanks.
