Looking for a 4 channel amp about 1000 watts.

[Pyrofan]

So im looking for a ok 4 channel amp about 1000 watts at 2 ohms. Plan on running 2 pairs of Pioneer TS-A6965R at 2 ohms and bridge 2 channels for a 500 watt sub.

PRICE: $100 or less shipped to Ga.

Haha, my bad. I messed up with the phone. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
Ok, so the sub would on be on 100 watts or would you bridge 2? Also, I cant tell if you mean scrap just the sub and do a cheap sub aero ported or if you mean scrap the sub and aero and just use a sealed 12. Which 12 would you recommend?

scrap your 500 watt sub idea from your first post. Scrap the 12 idea too. A cooler does not have enough airspace to make those thump.

Subwoofer Drivers in the Speaker Components Department at Parts Express | 14 check out some of the 4 and 6" or 8"subs or midbass drivers here. They actually perform really well in a ported enclosure.

i'd bridge the amp if you are getting a D2 sub or two D4. You need to wire for a 4 ohm load if you bridge.

I was not trolling the post. I simply offered what I had. You didn't like it, fine. Don't make it into something bigger than what it really was.

Its fine. Im sorry just thought it wasnt a serious inquiry thats all. Hard to tell what real and fake over the internet.

Why couldnt I do 1 or 2 of Dayton Audio SD215A-88 8" DVC Subwoofer and wire it 2 ohms? Im sorry if its a dumb question.

simple. Your amps will fry or go into protect because they are only stable down to 4 ohms when bridged.

Well then, thats not good. So would you say 1 or 2 8's? Ill try to find a 4 ohm stable amp at 100 watts.

EDIT: Then does that mean I cant run 2 pairs of http://www.sonicelectronix.com/item_63992_Pioneer-TS-A6965R.html wired together so they only use 2 channels since it would be 4 ohms.

need to know how big the cooler bucket is.

technically if you get an amp like the ppi p900.4, you can wire four 6x9 speakers two to each front channel. Then bridge the rear channels and run two 4 ohm dual voice coil subwoofers wired in series or one bigger 2 ohm subwoofer wired in series.

Lets say for example the precision power p900. It does 145 watts at 4 ohms and 225 watts at 2 ohms per channel. Means you can wire two 4 ohm speakers to a single channel and it'll have a 2 ohm load putting out 225 watts split by 2 speakers = 112.5 watts a speaker.

When you start bridging the amplifier, the lowest impedance you can go is 4 ohms. So If you get two 8 inch 4 ohm dvc subwoofers wire each speaker in series which will make them 8 ohms each, then wire them bridged to the amp, it'll split the 8 ohms down to 4 ohms a speaker which is stable.

You can do as much as you want but you have to make sure you are at the right impedance and make sure you have enough cubic feet airspace so you are not suffocating your speakers/subwoofers.

Oh, I didnt know the you can run the speakers and the sub at different ohms. Learn something new everyday. Here is a link to the cooler. Igloo 60-Quart Ice Cube Roller Cooler: Outdoor Sports : Walmart.com

I want to attach the box to the lid so when you open the lid, the box comes out with it. That way you can access the electronics.

Subwoofer Wiring Diagrams

For future reference. That works for both speakers and subwoofers. You can use any amount of speakers and subwoofers as long as you are at the impedance that you amp can handle.

Box is gonna get stuck at the lid if its too deep, and you really dont have much room for a lot of speakers or subwoofers if your whole enclosure is at the lid.

Yea, I know about that website. Used it before. Here is a link to what im trying to replicate ( I promise the site is legit despite the URL) motorboatyourself.com - River Cooler Radio 2.done

looks good, My 2 cents though, subwoofer should be downfiring and box should be at the bottom. When a sub has something to load off of, it hits a lot deeper and gives a more surround type of sound.

Hmmm thats an idea. Would you cut out a hole in the bottom of the cooler or just have room about the sub and box for it to breathe. I like the look of the one i linked a lot though.

yeah thats how you do it. Its just trade offs really. Nothing wrong with the first one, it'll sound more natural and crisp. The downfiring option will be boomier and ground poundy.
