i have a http://www.alpine-europe.com/switzer...sbe-12kit.html

and i also have this: http://www.alpine-usa.com/product/view/mrp-f300/ for my Earthquake SWS-8 4ohms.

i just ordered the mrp-f300 since my old bp tha555 broke.

will this be a good combination, or just too much?

Thanks!

Whether it is "too much" depends almost entirely on your tastes. 12s will reproduce lower frequencies than 10s, and if your music has a lot of deep bass, 12 inch subs will be better at it.

What I would be concerned with is the mid-bass. I have read that the Earthquakes are not as good at mid-bass as sub-bass, which could leave a gap in the upper bass region that neither the 4" door speakers nor the 8" subs would perform well.

I don't have an E9x yet, but I have a pair of 10s in the trunk of my Lexus, with 6.5s in the front, and I am still short on mid-bass. I would first try the 12 with the stock 8s and then decide if I needed anything else.

Hmmm.

But I'm not that selective.. I'm happy as long as it sounds better than it does now.

About the new MRP-F300 I just ordered. With that amp and my sws-8's, I can still use them as mid-basses right? As I said, I'm not that selective. My car isn't flawless. Hehe.

I have never heard them before, but this thread is pretty much what I am going by.

The f300 is perfect for the SWS-8s.

I have my stock L7 woofers amped with a M500....mono I know :/

I wanted to get an F300 as well but had the M500 laying around.

So they won't sound good at all? I'm new with this. So if the woofers won't work good as mid-bass, I might just use them as normal subs.

We will see, I'll keep you posted. The store just shipped it out though..

The only way to get the Earthquakes to sound decent at midbass is through "heavy" processing. If you don't have that capability I would put back in the Logic 7 woofers (assuming you have L7).

[piggelin]

I don't. I have the shitty euro-woofers. No hifi, no L7. Maybe the best thing to do is using thoose as subs

[piggelin]

any tips on wich settings i should use? sounds really bad now

[fdriller9]

If you're running the 2, 8" and a 12" you should bandpass the 8"s and low pass the trunk sub.

I have my L7 woofers bandpassed between 60Hz and 200Hz. Trunk sub is low passed around 65Hz. Play around with those settings. You may want the SWS-8s handle a bit more low end though.

Btw, you can make any sub too much. Just set the gain to your liking.
