drive sub off rear speaker pre outs?

[Digitalwave]

He would separate the amp and the subs, but we're not looking for any trades. I can get a price on just the amp if you want.

Find out what amp it is.... I need something with good solid power.... 500+ watts and needs to be able to drop to 2 ohms mono..... if this is a class D I should be good.....

[Digitalwave]

I'll try to find the specs, it does 1ohm and over 500watts and it is indeed a class D.

[marakka]

You da man! Keep me posted as I just worked a deal for 4 15's and need something for em.

4 15's

[Digitalwave]

I would think you need a lot more than 500 watts for 4 15's?

[nickmp0wer]

my friend has a box, 2 subs (one is busted) and an amp that he says he will give me for $30. he thinks the amp is 200 watts but he isnt sure.

[marakka]

I know I'll need more power.... but a class D affords me the flexibility to at least get em goin until I can get a second matching amp to do it right.... or 3 more or what not ;)

I found the specs of the amp. It's the Alpine V12 MRD-M500. RMS power at 2 ohms is 500x1. Go here and click on the spec sheet:

Hell.... for 30 bux you should be able to rawk with that. Just make sure the other sub isn't blown or if it really is then replace it. Find out what kind of amp you are getting too. All you'll need is wires and a couple hours to put everything in and you'll be boomin.




As far as the m500. Yeah... I know the amp. I want it. Tell him to get me a price. Let me know what you come up with ASAP. Ich mochte dammit!

Where do you plan on putting them Max?

Who needs back seats anyway?

[nickmp0wer]

do you guys think there will be enough bass comming out of the preouts if the recievers "x-bass" is turend off to drive the woofer? I guess i have a 50ft rca cable and could hook the preouts to my home stereo to see how much bass there is?

what can i do about a volume control under the seat or something?

also one of my mb quarts kind of makes a vibrating sound when there is some bass going through it. I cant really hear it from my seat but i know its there. the speakers look to not have any cracks or anything. any ideas?

[KenC]

I wouldn't use the "X-Bass." If you want the music to sound as the artist composed it, leave it off. However, if you're pimpin high school parking lots, you may want to leave it on.

Are you sure the speaker basket isn't vibrating against the sheet-metal?

If you're getting vibration from the mids, it's either distortion or you've blown the voice coil. If you're just running them off of the deck, then you either have too little power to them, or you've been keeping them at max volume and the amp was clipping and distorted them.

RCA Preouts = RCA preouts. The ONLY reason there are specific "subwoofer" preouts is for decks that have an adjustable lowpass xover in them specifically for a subwoofer. A deck with only 2 sets of preouts (front/rear) doesnt have that adjustability. You can use whatever set of preouts you want. Those go to your amp. As long as the amp has a lowpass xover, youll be fine. As for power, it depends on which subs you are using and what size box it is. Also what impedence they are. 2 ohms, 4 ohms, dual 2, dual 4, etc.
