I used to have a competition sound system in my old car and never installed on the new car due to many reasons. So I have all the stuff at sitting at home and decided to try to turn into a nice outdoor system for my backyard for the upcoming parties and summer bbq's.

I have right now in a box 2 12'' subwoofers, 2 super tweeters and 4 horn/loud speakers. I was told by a guy that used to work with me that I need to get a dj/home amplifier to hook it up that stuff since the 2 car ones that I have would be too much work to get them to plug into regular eletricity.

I've being looking on ebay for some amplifiers and I have no clue what to buy with so many options. I don't want to brake the bank and was looking for something around 100-150 bucks.

This is a picture of how my sound system use to look like in the car. May help.

Note: that's not a actual picture of my car, just a concept.

Yes I need something like that.. But I don't know what is the right one to buy.
1000 watts, 1400 watts, 2 channels, 4 channels. 4 ohm or 8 ohms. lot of questions.

Thats all based off the specs of your speakers I believe.
 
did you build the system or have it installed?

Need specs on what parts used, and how they were/are wired... crossovers (active/passive)? etc.

Honestly, for outdoor party's... I picked up a cheap set of "Outdoor Speakers" for under $100 (KLH I believe) from Costco, and just ran them to my home theater that supported two zones... Plenty of sound for Summer parties

the "outdoor" just means they'll hold up better to the weather...


might have to upgrade to these some day :)

I did some research. Car speakers are 4 ohms. Watts is just how much power they gonna throw out. I just need to know how many channels I would need for the amount of speakers I have

Outdoor I mean by it's gonna stay in the shed and I'll roll it outside and hook my Ipod to it. :)

I have speakers, all the wires and also the car amps. But I was told that the car amps would not be good due to overheating when wired to normal outlets through a converter. That's why I have to use a audio amplifier.

Not really... Speakers are rated for a certain power. They can only handle so much and they will state what they can push. Peak, RMS etc.

Your best bet is to either find an amp that is 4 ohm stable so you can run everything in stereo assuming you have 4 ohm woofers and appropriate crossovers between them and the midrange and tweeters, or get a power inverter capable of around 70 amps to run both of your amps off of.

Im gonna check the specs tonight and let you guys know.
 
You can use as small as 18 gauge, it won't matter. Good luck with it!
