Please help me figure out what I need

[mimcgl]

I have a basic understanding of car audio, but this will be my first system and I need som help figuring out what I need and how to wire it. BTW, this is for a regular cab S10. I will be getting infinity speakers for the doors, can't remember the model number but they are around 50 watts rms each at 4 ohms and I'm getting an 8" RE sub which is a 4 ohm DVC. I understand that you can only wire a 4 ohm DVC at either 2 or 8 ohms so I need to figure out what kind of amp woud be best for this system. Can you have 2 channels at 4 ohms and the other two at either 2 or 8 ohms? Thanks for any suggestions.

I doubt that there is any 4 ch amps that are 50w rms and can be bridged into a 2 ohm load.

Your better off buying 2 seperate amps

That's what I was afraid of, trying to avoid that due to more complicated wiring and lack of space. Should I just power the speakers off the head unit (which will be 4X25 RMS) and get a mono amp for the sub? Is there a small enough amp that I can power a 4 ohm DVC sub at 175 RMS that I can wire either 2 or 8 ohm? Thanks.

get a 5 channel amp or somthing similar. you dont want to run your door speakers under a 4ohm load (i think) and then the 5th channel goes to the sub. if you only have 2 speakers and a sub, just dont bother with the other 2 channels or bridge them @ 4ohms to the door speakers and keep the gain down. (these can be expensive though)

otherwise, get a cheap 2channel amp that puts out 100w, and then a mono amp that puts out 100w, and run 4awg wire from the battery, get a distrobution block that goes from (one) 4 guage wire -> (two) 8 guage wires, and power the amps this way. its really quite simple. the amps wont be very large, i assure you. i bet you can mount them under the driver\passanger seat. then make a PORTED BOX (please?) for the RE8 in the back somewhere.

its not really that hard =)

get a cheap mono\2channel 100~200w amp and leave the gains down for the sub

and get a 2 channel 100~200w amp for your mids\highs

easy.

Soundstream Rubicon 404 (50w x 4 @ 4ohm, 200w x 2 @ 2ohm bridged,

100w x 4 @ 1ohm) //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif Or step up to Rubicon 604 for more power (80w x 4 @ 4ohm, 300w x 2 @ 2ohm bridged).

Problem is finding them......they stopped producing them a while ago //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif But if you can find one, they are killer, killer amps!!

Would this sub sound better in a ported box? I'm more interested in sq but it obviously won't make any difference if I can't hear it in the first place. Also, the sub is rated at 175 rms, but its a DVC so does that mean 175 total or each coil? Thanks.

It would be louder with the same amount of watts

SQ ported is probably what you are looking for

175-200w RMS to the woofer is enough
