From what you told me, you should have dual voice coil speakers, each coil at 4 ohms. Wire the two coils in parallel, that will yield a 2 ohm load for each speaker and wire up each speaker to each channel (no need to bridge). That will pump 600 watts into a 400 watt rated speaker and that's fine. You'll probably won't clip the amp unless the setup doesn't give you the low end you desire, or you're just plain deaf. Food for thought. With that amp bridged, you could put 2 1200 watt speakers with dual 4 ohm voice coils as well. You'll also need capacitors for your battery line. The average is 1 Fahrad for every 1000 watts. Good luck with the boom-boom!

So if I upgrade later to 12' JL W7's then I would be ablr to run 1200x2??????Is that right i'm still working all this stereo stuff out and you seem pretty knoledgable...

The big problem of upgrading to 12's is the cabinet volume. The 12's need about double (1.3 cubic ft) to properly function. In a sealed cabinet setup (recommended) that measurement is for sound quality, but it's also the an additional suspension system for the speaker. Those 12's are a little funky being a 3 ohm speaker, and the wiring setup would be a little different, but you have more than enough power. Your problem is getting the speakers in there. You'll probably have to sacrifice your bench seat if you want to do it properly. My advice is stick to one size of speaker from here on out, and because of the space involved, 10's will probably be your best shot. The ones you picked only need around .6 cubic feet to be properly controlled.

The boxes I'm looking at are .97 and should fit ok...Who else makes a real good 10'? I think Audiobahn actually has a 10 that will handle 800-1000 watts right????

Hey Unsane,since you seem to know alot about audio,quick question.I have in my boat now a pair of Infinity 6.5's,70W RMS,210W Peak,and a pair of Infinity 6x9's,100W RMS, 300 Peak.To put some power to thoose speakers I'd need a 4 channel amp that's at least 350x4 RMS at 4ohms????:confused: Please help me out....Thanks

you don't need that much power. Something that makes about 100 to 150 a channel at 4 ohms should be more than enough.

There are several 10's that can handle close to 1000 watts including several by Audiobahn that can hold 1000 or over. Check out Fosgate and Kicker as well.

So if I get an amp the is 100wX4 rms,that means the amp is putting 100w into each speaker,right?How much difference do you think it'll make???It just has a head unit and no other amp...

here is what I have in my 223

2 8" Memphis audio subs
4 Pioneer 6.5's 4 way
2 6x9 4 ways
Fosgate punch 200 for the subs
Pioneer 100x4
Alpine Cd/mp3 (2nd from the best or so)

My subs are placed in truck boxes in the location you are talking about.

I wouldn't think truck style boxes are going to have enough room with the size of the magnet on W6's I doubt the will fit into a truck box that will fit in the storage area you are talking about, I wanted to use my w6 12's in that location and they where way way to deep. Like unsane said wire them in paralell. The w6 10's sound great, if you havent bought them yet you could always go with 4 10" subs with a smaller mounting depth and it would still sound good


Im adding either 2 10" Memphis audio subs in the same location in front of the 8's or putting one of the 12w6's somewhere like where the porta poty goes or under the rear bench, I am using the M-class sub designed for small spaces

I was actually just thinking about that,time to do some real accurate measuring...:( It will all work out in the end though,if they don't measure I have someone ready to take the stuff off my hands at a great price,and I'm actually condidering it anyways because of the offer.I got they stuff at a steal of a price,someone owed money who owed me yada yada yada....So if I do sell,here's what I'll do,I'm picking up a 4 channel amp,I think it's 85X4 rms at 4 ohms for cheap.So i'm going to put that to my 2 6.5's and my 2 6x9's,so that should sound good.Then i'm still doing the truck boxes with 10's,I have a set of MTX 10's 300w RMS,and still do the audiobahn amp.I think either way I go is a great START :D .Hopefully one day I plan to put another set of 6X9's,so i'd have 4 6x9's under my rear seat and then in the middle of the 4 6x9's put a JL W7 :drink: .I'm going to need more batteries...............:evilb:
