Hey everyone,

I need some help and opinions from you guys here. I currently have a pair of kicker 6x9 for my rear stage drivers. They were a cheap pair i got a year ago when funds were tight. They are starting to crap the bed (crackles at 75%). So I need to upgrade my rear stage. I have an infinity kappa four amplifier that powers 125 RMS @ 4ohms. Would you guys go with 6x9's, or would you put 6.5" in there instead. I've heard a few of you before say that you dont worry about the rear stage, but i personally love having speakers behind me. Not sure how much of a difference it really makes, but i definitely hear it and i enjoy it that way more.

I would love some input on what you guys think i should install. I also am struggling to find a decent set of speakers that handle enough power to be matched up with my amplifier. So, any suggestions?

Thanks,
Ben

I left my stock system exactly the same, then added to it. I have a 1600 watt multi-channel amp powering a two Kenwood 6x9s in the rear, and two 12" subs. I think it makes a huge difference, and I love how it sounds now. Stock system was a little weak.

How is the sound quality with that system set up ?
Can you discern the notes of a piano ?

I'll admit, it isn't the MOST high quality, I'm sure the guys following the SQ thread instructions get a much more balanced and crisper sound. But it certainly isn't low quality either. If I turn my sub control all the way down, I'd compare the quality of sound to the stock speakers, just much louder. When I start turning the subs up, it starts to sound more like a rap concert. Lots of bass, and you can still hear the music, but certainly doesn't sound like my sony studio monitor headphones that's for sure. I can hear piano notes just fine but they could be slightly crisper. Overall I'm very happy with it for spending less than $400 on the entire package. And knowing what I know now, I'd do it again.

Note: Here's the thread I was referring to.

Thread Flame War deleted. Let's get back to trying to answer Livingtheforce's question - anyone have suggestions for a good set of replacement speakers for him?

Any speakers in the rear deck are going to sound boomy compared to the same speakers in a air flow controlled speaker box. This includes Drivers and Tweeters. The reason is the rear deck doesn't provide a sealed environment for the speakers to work against.

This is also why some of us actually prefer the base stereo's sound quality over the Pioneer upgrade system - all our speakers are in "speaker boxes" of some sort. Door's aren't high quality speaker boxes, but they're definitely better than the floating rear deck.

Front stage is phenomenal in my opinion. I know that in theory, it could be better. But in practicality, it is perfect for me. I love my current setup, besides my rear 6x9's.

I love my DD. I finally got the top screen to work (ended up being bent pins on the GMOS adapter).
My current 6x9's (as well as front stage) are inside foam baffles that really help drive the sound outwards in my opinion. I love them

I personally have
Hertz Audio (Italian hand-made speakers, same company as Audison) speakers all around: Hi Energi Component in the front, Energi in the Rear door Coaxials, and Energi 6 x 9s.
with a JL Audio 10W1 in custom ported box. Powered by a top of the line (forgot the name) Alpine 5 channel amp; fed to factory head unit via an Audio Control LC6i EQ.
The Coaxial speakers aren't amplified, but the front and 6 by 9s are.

I absolutely LOVE the additional 6 by 9s. I added them after everything else and changed the amplifier to power them instead of the coaxial speakers, and it sounded alot better. Full range. Can hear every piano note and nearly every frequency that the human ear can hear. (the whole system was electronically tuned with an oscilloscope). Incredible depth and clarity. Not too bright at all (a la JL Audio speakers). Car has numerous sheets of Dynamat Xtreme Sound Insulation, in the doors and trunk (this helps ALOT). I can blast it at max volume (very very loud, but clear) for hours and hours without any power lowering, cutting, overheating, or ANY distortion. This is the advantage of an oscilloscope/microphone/computer audio tune.


Thus, I personally recommend Hertz Energi 6 by 9s. Now, Hertz is a hardish brand to find (at least from a certified dealer) and their products are EXPENSIVE.
However, the Energi Speakers are only the second highest up in the lineup, and even the lowest ones, the Diecis, sound great and are not too expensive.
You also cannot go wrong with any of the Audison speakers (although I'm not sure they make any 6 by 9s). If you want speakers that are more loud and bright, go with JL audio (C2 or above) or Focal.
A good compensation choice that you can't go wrong with would be any Kenwood Excelon 6 by 9s.

No problem man, for 6 out I would use the Audio Control LC6i DSP/EQ, Love it. Have it in my G37, for over 3-4 years with no problems at all.

In my Cruize I need 8 out so I have the Audio Control LC8i .. also love it, no problems!! SO i recommend the Audio Control LC6i for 6 out.

You guys really need to check out the miniDSP. 36 parametric EQ bands, time alignment, and crossover slopes up to 48db/octave. All for about a hundred bucks.

I assume you've read my SQ car audio V2 thread, stuck at the top of this section?
