Have some crappy oem 6x9 on my car. I'm in the market for a basic 6x9 for the rear. THey will be power by stock HU . I hAVE $100 Budget to work with. I'm not looking for anything mindblowing, just some decent bass and sq.

Your stock HU has no power. 6x9 are for midbass.

Honestly, if I wanted to replace rear speakers using stock headunit power i'd get something <$50~ with low watts and high sensativity.

Those would be my three choices for the sub-100 dollar 6x9s on SE in order of preference. The JBLs are the most sensitive (meaning they'll perform louder at lower power) and the Pioneers are the least sensitive, but we're only talking about a difference of 94 vs 90db here.

I vote for those PPI that Mr neo_styles has recommended, or take a look at some Lanzars,or Polk Audio

If you can lift your budget a smidge, you could also look at this pair:

JBL P963 6" x 9" 3-way Power Series Speakers - Sonic Electronix (http://www.sonicelectronix.com/item_12264_JBL-P963.html)

Basically as sensitive as the GTOs, but you get a better crossover network and I'm a bigger fan of the cone material. For some reason, the Power series was always the punchy member of the JBL family.

Also, talk to mylows10 ; about pricing on this pair which would do fine on HU power, but shines on amplified power:

If he ever plans on amping them Neo then I'd suggest some of which you posted. But he's using a h/u that puts out <10w rms (guesstimate) and is using it as rear fill. I just don't see the point of spending $60+ in this situation.

Ehh fair enough and apparently I skimmed right over the factory radio part.

OP, you'd probably see more gains just from amplifying your speakers rather than replacing them. Try that first, then revisit replacing your 6x9s

OP, try these first with your stock speakers and see what kind of difference it makes. Then consider upgrading your speakers. Just need to be doing this in the right steps...

I've never been a fan of Infinity tweets, so you'll most likely be using the attenuator on those. I think Infinity is being a little generous in its FR response, as well. Otherwise, they are spec'd scaringly similar to each other.

I think he should go with the Lanzar off of the HU power, and get funds up to do a very nice install for amped speakers,and a single sub set up,and not waste money on good expensive quality speakers that will more than likely get clipped to death from distortion.Keep it simple I say, till you get the funds for a entry level set up.I think you will be surprised what the Lanzars can produce for you for your money.Just my 2cents

I'd toss my idea. Morel Maximo 69C coaxial speakers. Morel Maximo have reputation for good sq, specially if you can run them active, and for good sensitivity. I think they will sound ok of head unit power, just don't crank the volume too high.

Think he is just looking for coaxials man...

Well they are both made by Harmon and yes the tweets like my Perfects absolutely have to be attenuated. I have 2 pair of some 7 year old JBL 6x8's P6852(?) from the power series with that same cone material. One went bad so I dissected it. No attenuator on the tweet, cleaner but didn't do lows as good as my Pioneer TS-D6802'S

The TS-Ds are just a great set for the money across the board. the 6.5" comps come alive once you remove the passive crossovers and run them active.

Polk db691 are $85 on ebay and 93db sensitivity which is great for what you need.

What?

The noob responses have been awesome recently, but alas... no fun can be had outside of the dome, lol.



OP, if you MUST upgrade the rear stage first and you have $100....

1)Get a cheap pair of planet audio, rockford, cadence, etc, etc, whatever, 6x9's for <$40(you can get some audiopipe ones for like $25). And do a good job installing.

2)Then get a cheap 2 channel amp with high level inputs (or a cheap loc, too) for <$50(these are on CL, ebay, and here for that, everyday)

3)Get some cheap power wire and terminals with what's left. Should be enough there.

Just to add my 0.02... if i were to upgrade anything first, it would be the head unit. And then, the front speakers. Get that x396 in the classifieds(its $100), or another decent hu. Thats the best way to start, not with the rears. In fact, I uninstalled mine.

That whole line is fantastic for the money.
