WTB: MM6501 Crossovers

unrealii

Shoot me a message if you've got them!

unrealii

still interested if anyone has a set.

cadenceclipse

lose yours?

unrealii

Nope, I want to bi-amp from the factory stereo. The car is a mr2 convertible, so with the factory setup now, the rear channels from the radio are not being used.

Thank you polk for dropping the bi-amp option on your non-sr crossovers >(

cadenceclipse

damn. sure u know, but u could also get HU or processor...good luck..

unrealii

yeah, trying to keep the install very simple. Its a convertible, so dont want to give thieves any temptation.

cadenceclipse

audiocontrol (under the seat)

unrealii

I'm going the HU route. No more need for x-overs.

Systems

Pioneer Premier DEH-P800PRS. I've used the older model, 880PRS with amazing results. Talk to someone who knows this product and you'll be wanting one.

good 4 u real! what'd u get??

Haven't bought an HU yet. Looking at either the Eclipse 5030 or the Pioneer DEH-P710BT. Any other candidate HU's, please suggest.

I'm a big eclipse fan, but I am leaning towards the pioneer unless I discover some flaw in it.

Here's what I'm looking for out of an HU:
-Bluetooth calling. If it can sound clear with the convertible top down, that would be awesome
-some form of a configurable crossover to play nice with the polk audio MM6501 and blaupunkt tha 555 amp. I have no rear speakers so I need to figure out the best way to run a 3-way setup - active is possible. MM6501 are 2.7ohm when using the included crossover and the blaupunkt amp is rated 4ohm in bridged mode. Not sure if it will like the 2.7ohm draw.
-most likely paired with a polk mm840 subwoofer - haven't bought this yet. Funds not available
-Clean looking and easy to use without looking as the radio placement is near the stick shift
-plays nice with nokia 5800 a2dp - a must
-plays nice with 1g zune - nice to have

amp ratings:
-4 ohms: 55 watts x 4 chan. + 200 watts x 1 chan.
-2 ohms: 65 watts x 4 chan. + 250 watts x 1 chan.
-Bridged, 4 ohms: 150 watts x 2 chan. + 200 watts x 1 channel

what r you bridging for? not mm6501s mm840? amp will b fine using ch 1 and 2 for polk mms. bridged at 4ohms for sub will b fine also

i think cde5030 will b fine with bluetooth, xover, and everything else actually..actually not sure about zune, but i think

is that eclipse available anywhere??

unrealii

I would bridge for the mm6501's. I dont think I can run one channel per tweeter/mid unless the head unit supports 3-way x-over. Not sure if between the mm x-overs and the amp I can cover all the cutoffs. Will have to see when the amp arrives next week.

cadenceclipse

how do u bridge for the mm6501s? i thought your main reason for going HU route was to bi-amp among others..if u bi-amp u will b using all 4 channels. ch 1 and 2 for tweeters and 3 and 4 for midranges. guess your right. if amp supports it(bandpass) your ok otherwise u'd need 3-way HU, which u could use anyway, and/or audiocontrol..

unrealii

Hah, I decided to go HU route for a cleaner signal and bluetooth since the car is stickshift. I also like the idea of steering wheel remote as I'm always fiddling with stations. That is why I am leaning towards the pioneer 710bt.

I dont want to spend too much on a head unit (consider $300 the ceiling price), but at that price, I can't find anything which has all the features like bluetooth hands free and a 3-way crossover. I dont want to go the processor route either.

So, plan B:
I scored a great deal on a set of SR6500's. I can either bi-amp them now, or run them in 2 channel mode and bridge my amp to power them (reason i am considering this route as to give my mids more headroom than if I were to bi-amp, of course my ears will be the decider). Since they run at 4ohm in 2 channel mode, my amp shouldn't give me any issues when bridging.

unrealii

Got a great deal on an eclipse cd5030. I was leaning towards pioneer DEH-P710BT, but after reading too many horror stories about noise in the RCA's and other things, I was put off.

Waiting for my amp to arrive on monday.

cadenceclipse

sweet! where?? how much u pay?? i think u'll really like it. keep us posted on what u think. no 3-way, right? ps. no bridging! what u mean bridge??? u run them 4ohm stereo right? biamped or not...

unrealii

I paid $250 for it brand new. I called the shop and they gave me the price, I literally ran over there and bought it. I'd feel bad if that price is under their cost :-0

Yeah, no 3-way. Not sure if I will run them bi-amped or bridge the amp and run the 4 channel part in 2ch mode. Reason being is that my buddy (he recently switched to 3-way active) felt his midbass was much more stronger running his speakers in 2 channel because his mids had more watts of headroom. For me, Bi-amping will give each speaker 55 watts each, or bridging can give them 125w split among a tweeter/mid. His speakers weren't polk though, so I dunno. I'll try both. Bi-amping would give me more tuning options with the EQ on the HU - but I have lots of faith in polk's engineers and the crossovers

cadenceclipse

sweet! and nice price! but how the heck will u bridge?? dont make sense ps i want your MM6501s! live close 2 pa?

unrealii

To bridge the amp, I just connect the speaker wires differently to the amp. Shoot me a PM if you're still interested in the MM6501's. I'm in socal.

cadenceclipse

u can't bridge em. well u can but u'd only get 62.5w x 2(125w x 2 but since not dvc, only half) instead of 55w x 4. boy would i like those mms..

unrealii

No, I'm not bi-amping the SR's. They'll present a 4ohm load, which when I wire to the amp will be 125w x 2.

cadenceclipse

how do u get 125w x 2? don't u need DVCs??
