A little guidance needed in matching up system

**damarble** · 07-19-2006, 02:40 AM

So far I've read until my head is about to explode and I haven't even touched the tip of the iceberg when it comes to car audio. I hesitate to ask advice from a audio shop because I can tell they either don't know what they're talking about, and/or want to sell me the most exspensive stuff. I'm not trying to build a show winning system just something that sounds nice and clean.

My car uses 6.5" speakers in the front and 6x9" in the rear. So far I have a pair of Infinity Kappa 60.7cs components for the front that are rated at 2ohm, 90w RMS. I also have a older RF Punch 400a4 amp, rated at 4x50w at 4ohm or 4x100w at 2ohm. The rest of the system in still in the air at this point. I'm unsure if I should just use the comps up front and not use rears, just go for a sub(s) (with 2nd amp of course). I'm getting conflicting info on whether that is a good solution or not. It would work out perfect for me mounting the subs, as I could put two 10's under the rear dash where the stock 6x9's were, there is plenty of room, and that would save me a ton of trunk space too.

So any suggestions? I have zero experiance with car audio, just what I've read. I like many people here am a computer geek first, audio afictionado second.

I'd ditch the 6x9s, but I wouldn't mount the subs under the rear deck. You'd need freeair subs and they're not that great performance wise. Also, by bolting a sub to the rear deck you're looking at a great way to find rattles that you'd probably never run into otherwise.

thats what i'd suggest. that's what i did and it sound pretty great imho. save the money on the rear speakers get a better set of comps for the front (4 ohm version) and a nice sub or two in the rear. Image dynamics and elemental designs make some great inexpensive subs that play well with relatively little power.

ditto what scott has said.

whatever product you go with, I recomend staying with well known name brands. None of this Rage, boss, jensen, etc stuff you find at wal-mart or the flea market. ID makes great subs that work well on little power and in little air space.

I have no first hand experience with eD but people seem to love em.

Thanks for the input!

Dammit I should have asked before I bought these comps. (Just 3 days ago

) Why should I be looking for the 4ohm versions? And I really don't want to spend more than I did anyway. I was originally going to go with the Infinity Reference series instead as I thought they sounded damn good for the price, much better than my stockers, but the Kappa's weren't that much more.

easy answer....you'll get better sound from an amp pushing 4 ohms rather then 2. about half the power from your amp though..but you'll notice an improvement in sq.

that's a damn fine place for that jensen...possibly even in the trash compacter

I guess I better throw the jensen 6 x 9's with it as well.

How much of an improvement? Obviously not "double", but if you could put it into numbers or percentage (I know, hard to do) how much better?

So what's the point of making a 2ohm speaker? Just a cheap way to raise the wattage rating?
