i'm buildign a "work radio" i work at a wood shop and am takign an old 200watt mp3 cd deck, 12volt 450watt power supply and 2 400 watt 6x9 speakers and buildign a box to house it all. now with only 2 speakers, can i wire up 2 positive wires for the 4 speakers that wold be in a car to each speaker and have 100watts x 2 instead of 50 x 4? and what can i do for a makeshift antennae? idk if i can find any antennae cables layign araound. any help is greatly appreciated.

ps, my camaro won't accept the deck, and i won't butcher it cus it's got the workign star wars staulk mounted deck.

 

Ah, a digital dash/radio person. My girl friend's dad just bought a sports coupe with one. It looks pretty funky.

Stereo: general fyi, your head unit is probably putting out closer to 22 watts x 4 for a total of 88 watts vs 200. Also, 400 watts would kill most any 6x9. Not that it matters, just putting it out there

In terms of what you're talking about doing the concept you outlined is called bridging. It's common pratice with amps but I'm not sure how a head unit would like it. NEEDAZ will most likely see this post in the morning and will be able to give you a much better answer than me.

 

So I'm that predictable Gummie?
Any way, NO you can't bridge the output of the HU (make and model is always nice). The HUs internal amp is already 'bridged' inside the amp. See, the HUs internal amp (4 channels out) is made up of 8 single ended amps in groups of two operating in BTL mode (Bridge Tied Load). Trying to bridge the outputs would not make it any louder, but would more then likely over heat the amp IC. Just use the front or rear outputs.

 

No, you just know about a million times more than me when it comes to headunits and amps
