Amp advice for a newb

[JunkTitleGolf]

Yes that is a line out converter. Best buy should have one though if you buy the amp there. I think installation is free on basically everything from there. So just tell them what you have and they should be able to suggest something.

I wouldnt suggest any amps from best buy overpriced, and i think its good for anyone to take some time to learn how do an install. My first wiring job was less then average. But its good to learn it first hand.

But if you want to go the way of best buy the sony will do the job.

If the car didn't have to last me a few more years, I might try, but I'd rather not f' up my car by screwing up. Not to mention, I also want it to look nice, which wouldnt happen if I did it. I found a place that will do the install for me, waiting to hear back on some estimates from them. I might buy my amp from them becuase it would be cheaper for the install, just depends on if they have what I need.

Ok, so, one more newb question, showing how inept I am. I was reading something in I think it was the manual, maybe it was a website, about being sure to match the combined ohm's of 2 subs to the ohms that an amp can handle. Can anyone make sense of this for me? I figured it was just I had two 4 ohm subs, so the amp would/should run at 4 ohms to work correctly. The word "combined" in there is confusing me.

combin is the way you wire it you have 3 options;

parrell (to find that will add the ohms up and divid my the number of subs i belive)
series (to find the total ohm you just add)
series-parrell(i think you need at least 3 subs for this)( to find the total ohms you need to divide each section into series and parrell then add the two together

That depends on the amp. Some amps are stable down to .5 ohm, the majority is 4 ohm and 2 ohm though. There mainly saying dont mix the impendance. Such as a 2 ohm load on one channel and a 4 ohm on the other. To keep it simple i would keep the subs matched to the amp at 4ohm. So SVC (single voice coil) subs at 4 ohms each and a 2 channel amp that has such and such power at 4 ohms should be the way to keep it.

Ok, so as long as I have each sub on its own channel (I'm gettin a 2 channel amp), and the amp is 2x100 watt RMS @4 ohms, I don't need to worry?

Let me make that a little clearer since both subs are 4 ohm and the amp is rated at 2x4ohm ie 2 channels at 4ohms=100rms so yes it will be fine. It wouldnt be good if you had one sub a SVC and the other a DVC and you put the svc to one channel and the dvc to a another channel so 1 sub at 4 ohms and the other at either 2 or 8 ohms then it wouldnt be good for the amp.

So yes it will work. Sorry for the length of explanation but ive seen people put 2 different loads to the same amp. And it didnt end good.

K, I'm still working on understand Ohm's Law so I can actually understand it, but I do get what you mean. Thanks.

No problem

Ok, I found this amp, and it seems like a good deal. The RMS is 125x2 at 4 ohms, which is still under the max rms for the subs, it's Pioneer (respectable brand), and it's pretty cheap. What do you guys think?

Oh, and best of I won't need the line-out converter, it comes with speaker level inputs so it will work with OEM head units.

I had one of those once. It was nice. I don't know if anyone else has experienced this or not but when I used the hi input instead of RCA I got feed back. But for subs it shouldn't matter.
