I just have a quick question. Do the Polk/MOMO MM2084's fit in the doors? It is only 3/8 inch deeper than the RF Stage 2's . I am aware that some cutting is needed, but is it too deep to fit in the doors at all? (Yes, I will get a new amp (x2) as well)

The specs look stout for only an 8 inch sub.

Thanks

If you're willing to cut the back out of your enclosure, then yes, they'll fit. They're also nice little woofers. If you're going to hack, though, go with a Crystal CMP8 or an Ascendant Audio Assassin 8 or even a SoundSplinter RLi-8. Beastly little ****ers that will negate the need for any rear subs.

Thanks Infinity for the reply...

I'll look into them!

Thanks

Hey Infinity, there is a great deal going on until June 23rd for the Assassin 8....45 bucks each!! What is the frequency response I should expect from these?

What amplifier would you suggest for these 2 subs?

Thanks

Infinity

They'll take 450-500 RMS despit the ratings, so basically feed them whatever you can afford. Something like the Directed 750D would be in the sweet range for decent money. If you want to keep stereo separation , it'll take one hellacious stereo class A/B amplifier, or a decent size 4-channel bridged. Something like http://www.ubid.com/Kicker_KX650.4_650W_4_Channel_Car_Audio_Amplifier_ 04'_Series/a10700436-rsearchall.html

Be warned, that Kicker amp is HUGE.

Here is the final RF look. With the factory sub they sound ok. would do better with an amp.

Those match up to the IUP semi-decent. Not bad, but I HAVE to have grills on mine, whether factory or not. I hit them with my foot every time I exit the car.

now i did find 8" diameter sub with 3.75" mounting depth compared to the RF punch which is 4.06" depth and SoundSplinter's 5.60" depth...but will the 8" diameter fit and how much cutting would i need for the depth

I was looking into possibly buying those. Any issues with install?

#6Fan

You have to do some trimming on the back side of the door panel (nothing a little fiberglass can't fix and you also need an aftermarket sub to make it hit harder. Which I do not have...

No trimming was needed with my install of the RF 8's. I did use a heat gun to soften and then mold the enclosure to fit.

knucklehead_11

U mean aftermarket amp to make it hit harder... I gotcha... thanks!

#6Fan

yep amp..sorry

knucklehead_11

oh yeah i meant to ask... i'm assuming u got the 4 ohm subs but were they 4 ohm or 8 ohm?

razorbackhogs

Okay...here are some more noob questions...

Alright, let's say I purchase a pair of 8" SVC 4-ohm subwoofers rated at 200W RMS.

If I want to put on a 2 ohm load, would I want 400 watts RMS x 1 at 2-ohms , with 200W RMS going to each speaker?

I guess what I am asking is, what is the best match for a pair of 8" SVC 4-ohm subs each rated at 200 watts RMS? (either RF S2 or MM2084)

Would this be the maximum RMS rating that it could handle?

Thanks

Yep, the power would be fine (even more would probably be OK), just make sure you cross low (<150Hz). Also, you would probably need a class D amp, since most class A/B amps won't handle 2 ohms mono in bridge mode.

Okay this electronics talk is giving me a headache. lol

LOL that's what beer is for!
I hear ya, eventually it becomes a constant migraine

Infinity

LOL, you got PM, bro.

knucklehead_11

If only I could have one right now, lol.
