so i have the stock premium system in my gen7 and i have a system from my previous car. now my question is i have some jl audio tr 6" coax  speakers 4 of them http://mobile.jlaudio.com/products_comp ... omp_id=242 (http://mobile.jlaudio.com/products_components.php?comp_id=242" onclick="window.open(this.href);return false;). i also have two jl audio 10" w1v2's http://mobile.jlaudio.com/products_subs ... ries_id=15 (http://mobile.jlaudio.com/products_subs.php?series_id=15" onclick="window.open(this.href);return false;). so my question is should i use the jl speakers and the subs or wait and use the stock speakers with the subs. if thats not clear i am wondering if the stock speakers can keep up with the subs  enough to sound good.

You should definitely use the JL speakers with the JL subs. The subs will overpower the stock speakers by a large amount.

Yeah make the upgrade.

At their optimum wattage both of the subs will produce about 250w RMS, and the total wattage of the stock sound system is about 200ish watts peak I do believe.

thats what i figured but the jl speakers seemed under powered compared to the subs but those subs are very surprising. i guess ill just run the coax till i can get some components. my real question i guess was i had no idea what the stock systems specs were and didnt know how to compare

I'd run the aftermarket speakers.

so i think i have decided to run the jl's for now but upgrade the system to full alpine type r speakers and subs. the next question is you guys opinion. 6x9s for the  rear deck or go to another set of 61/2 components. fell free to say anythign you think about this including other sizes and speaker types.

Oval speakers have more lateral cone movement, and that causes distortion.  My vote is for round speakers.

thats what ive always thought but was just getting second opinion. so now the question is do i put coax or component in the rear and what do you guys think of the alpine type r stuff?

The front speakers are more important than the rear speakers.  I wouldn't put too much time or money into the rear.

i disagree . . .  if you want good sound i would recommend changing fronts + rears and adding the sub. After that if want better sound quality that is where you can add and aftermarket radio and a 4 channel if necessary.

Really?  You disagree that the front speakers are more important than rear speakers?  Maybe I just have a different approach to things since I always plan out complete systems instead of just swapping speakers and adding a sub.  I have never been a fan of adding a sub and using aftermarket speakers with the stock head unit.  Of course, not everyone is looking for the same quality I expect from a sound system.  Some people are happy with just a sub and call it a day.  I still stand by my statement that the front speakers are the most important choice you can make when building any kind of quality sound system.  I don't know everything, but I do have enough experience and a decent background when it comes to audio.

I'm going to have to side with Tim here. Since you're going to be the one in the car alone most of the time, its all about staging. You can replace your rears but you should focus more of your funding towards the front. The rule of thumb is 90/10. Everyone has their own tastes  when it comes to sound but if you have too much speaker in the rear, you'll miss a lot of the higher frequencies you'd get out of the front. Besides, Tim's car is a rolling concert. I've never heard an auto sound system set up like his. You'd pop in a live recording and you literally feel like you're in the front row.

I'm not trying to discount Gus' experience.  He did say he is an MECP installer at Best Buy.  I'm sure he's installed plenty of speakers, amps, subs, and head units in his time.  I just make suggestions based on my experience and what I was taught by a MECP certified Master Installer who has built competition vehicles and has had his work featured in magazines.  I'm sure that Gus made his suggestion based on his experience also.  We may have different opinions, but we were both trying to help.

I hear ya man. I've built systems like what Gus is saying and after hearing yours, I was floored. I felt like I was doing it wrong all this time. Again, its all based on each person's perspective.

Well ppl have different taste when it comes to car audio. Alot of people enjoy having a little more bass then voice but at the same time there are alot of ppl that like to have more voice then bass. Not everyone listens to the same type of music, but i agree with Tim. I'm not a fan of having aftermarket speakers with a stock deck because that stock deck can only put out so much. But when it come to aftermarket radios you can have a radio that has 4v or even 5v preout which does make a difference in quality. But I'm not going to lie i have installed several rockford 360's and about two jl cleansweeps and ohh boy do they improve the sound quality of a factory system. 

i dont really disagree with that but i dont think its worth the time to just swap out the front speakers only, i would just replace all the speakers at once. For example lets say if you own a big company business and a light bulb goes out on the top/roof. Wouldnt it be alot cheaper to replace all of the bulbs and only pay for 1-2 hrs of labor or would you rather change the one that went out and pay 1 hr labor for each bulb that goes out? lol its a little of track but you guys should get the point lol 

I think what Tim was referring to was to replace all the speakers at once (Let's face it. They suck donkey schlong). But the 90-10 was to get off the chain speakers up front and decent speakers out back. Can't build a quality setup using factory components.

It's all about where you're coming from.  For budget minded people that don't have a lot to spend, I'd rather they spend more money on the front speakers, and get a good set, instead of blowing 1/3 to 1/2 of their budget on rear speakers.  I'd suggest that they keep the stock rears and replace them at a later time.  Another highly underestimated and very cheap upgrade would be to remove the speakers and make a gasket between the speaker and the rear deck to seal it off and reduce backwaves.  For a cheap solution, it makes a noticeable difference. 

true i agree with you there if moneys tight focus on the fronts then work your way to the back,lol we use monkey snot to seal speakers

well i know this was along time ago but bettween work and school i never got around to this. i have an aftermarket head unit the speakers subs and amp from my last car like i said another good question here is should i leave the stock tweets in along with the coax in front and back or should i just take them out cause it would be to much in the treble department.

The stock tweets are absolute garbage. Replace the fronts with a good set of components to get a good, clean front stage. Throwing coaxials anywhere is just straight dookie. You won't get a quality sound out of coaxials. If you must use your coaxials anywhere, throw them in the rear deck.

You can do whatever you like.  If you use the coax speakers in the front, and disconnect the stock tweeters, the imaging is going to change.  You're basically going to be aiming your tweeters at your shins.  I guess the only thing I would suggest is that you leave the tweeters connected, then listen to it.  If it sounds too bright, you can disconnect the tweeters.  If it sounds like shit after that, you can reconnect the tweeters and attenuate the treble on your head unit.

Yeah. That works too.

i know i need components i just dont have the cash for it right now so im kinda stuck and trying to figure out what i should do im wonder ing if i should just wait to do all this until i get some cash for components in the front lol

also to add to that can aftermarket tweets fit in the stock location

Some can and some can't.  It really depends on their size since all aftermarket products are not identical. 

these are the ones im gonna be using whwen i get components will these fit you think http://mobile.jlaudio.com/products_components.php?comp_id=125 (http://mobile.jlaudio.com/products_components.php?comp_id=125)

As in will the tweeters fit in the stock locations

figured id post this here but i do need a little help im good at the wiring part but when it comes to tuning an amp i have no clue. any help with tunning it wold be much appriciated and if you guys need further info let me know.

What do you have?

As far as if the tweeters will fit, I don't know.  I've done installs where they fit just fine in the stock location and other installs where you have to cut the shit out of everything to get enough clearance.  I would only suggest that you choose a 2nd location in case the tweeters you want don't fit there.

As far as tuning your amp, it kinda depends on what you're running.  Honestly, there are no rules for tuning an amp, other than using your ears.  One thing I would suggest is that you tune the crossover frequency of the rear speakers higher than the front speakers. 

To give you an example:
My front speakers are crossed over with a high pass filter at 80 Hz and a 12 dB slope.
My rear speakers are crossed over with a high pass filter at 100 Hz and a 12 dB slope.

These are just general recommendations, and most amplifiers don't have the kind of precision that my audio processor has.  If you post a link to the owners manual for your amp, I can take a look and see what adjustments you have available.

http://www.pioneerelectronics.com/PUSA/Car/CD-Receivers/DEH-P6900UB this is the headunit I am using.


http://www2.panasonic.com/consumer-electronics/support/Audio/Mobile-Electronics/Power-Amplifiers/Operating-Instructions/model.CY-PA2003U.O
This is the amp I am using.

http://mobile.jlaudio.com/products_subs.php?series_id=15
And these are the subs I am using.

I have them hooked up one to each
Channel someone told me to bridge them but I thought it would be a bad idea to bridge it and hook two speakers up to one bridged channel. Also the subs are in a sealed box that is quite a bit larger than what the recommended specs ask for. Hope this helps!!

Okay, here's the problem.  The amp you posted a link for, does not have an owners manual available.  The tech specs do not say that it can be it can be bridged.  Since there's a lack of info there, I wouldn't try it until you confirmed with Panasonic first.  I'm guessing that it can't be, otherwise it would be listed.  The other problem is that you listed two different subs.  It's really hard to say how they should be wired up if you don't know what you're working with. 

The last thing that I will try and make you aware of is that if your box isn't the appropriate size for your subs, you will not get good sound and they will be damaged.  The manufacturers make these recommendations for you to get the best sound quality, but also because if the box is too big or too small, the suspension of the sub will not work properly, the cone will move laterally, causing heat in the voice coil, and it will eventually fail.

I don't see the two separate Subs listed it's the 10w1v2 4 ohm subs though as far as the amp goes I have a copy in PDF format on my computer when I get back from vacation next week I can send it to you if you want to pm me your email. Any other info you need just let me know

Edit( sry I'm dumb I see what you mean by two diff subs it the 10w1v2-4)

Here are pics of the adjustments and connections sry didn't have a copy of the manual anymore (http://tapatalk.com/mu/43b1441f-8746-53ef.jpg)

Also if you need the manual for the head unit I can provide that
