let me start by saying all you guys are awesome here and i have been looking over this board for the past few years (forgot my old account.) Hopefully my plans are logical. (low buget of course)

93 honda accord

1.) front door. need new mid-bass drivers!! I have a set of alpine type R comps driven by a poweracoustic amp with 150 rms x2. have the gain set at just under 3/4 and my mid bass drivers blew! (rms rating must be off. says 110 on box i think) I need a good set of 6 1/2 midbass drivers that will match well with this crappy crossover & tweeter. dont really know what to get besides just matching the crossovers freq's. but seems like there is not much out there. *Also should I buy those baffles??

2.) I want to get a clarion 7 band eq. so what kind of mounting bracket do I get? I know there is room for a second slot but I'm not too familiar with this dept. I am constantly adjusting my levels from each cd so an eq is needed!

3.) SOUND DEADENING. this is gonna be a project from hell but I was just going to maybe get some peal and seal for my trunk. (have two 12's. not a huge bass guy just like some low end.) and maybe get some dynomat for the front door panels because I understand the concept of needing some type of "enclosure" to get any decent mid-bass.

also for items 1 & 2 if there is a website that has almost all that stuff so i dont have to order from 3 places that would be cool. (2 is understandable lolz) I know it sounds crazy but I can only spend just over $200 for all of this. so what do you guys think? thanks

OK 1: If the midrange drivers blew, it was caused by either the gain being set too high (most likely) or the car's inability to supply enough current to teh amplifier(s) due to an insufficient charging system (honda commonly uses tiny alternators) So consider turning the gain down below 1/2 on the amp, and maybe a HO Alternator upgrade.. maybe 130A alt or larger?

Also, consider just replacing the type R components. A new set isn't that expensive, and you can't really just replace the midrange drivers for those with something else, and Alpine doesn't sell just midrange replacements.

the baffles just protect the drivers from weather, like rain getting into the doors. If ya need em, get em.

This look like you?
If so, personally, I'd buy some black ABS plastic and fabricate a dash plate to mount the EQ where that pocket is below the radio.
The cheap way to do this is just remove the pocket, cut the back out of it to run the wires, and mount the EQ to the ceiling of the pocket using the included under dash bracket for the EQ. The ABS faceplate just makes the EQ look flush mounted and professional.

midrange speakers don't need enclosures. they are designed and have the thielle-small aprameters to work in IB (infinite baffle. no box.) in doors. The sound deadening just improves efficiency by preventing loss of energy via resonating metal, and decoupling the driver from that sheet metal. Look at a product called SecondSkin (google it) instead of Dynamat. Mat the doors front and back, and do the trunk (its not really that hard. takes a weekend at home) and if you have things in the trunk that rattle, try expanding foam (SPARINGLY) to put some pressure on metal that vibrates against other metal or plastic panels. things like license plates you can "stick" to the car using dumdum (windshield sealant. that black goopy crap they use to put in glass on cars) between the plate and the car body.

I think you should save up more money and do this job properly. That' as you asked, is what I think.

ouch thats rough! through all this time and research i thought I had midbass drivers for some reason... So if thats the case could anybody recommend me a set of good comp's for around $150? I honestly dont really like the way these type R's sound. good thing i paid $125 for them... So I couldnt get any real midbass in my door huh?

I'll start looking into mounting the eq in the bottom pocket... I dont even know how to wire it. but that should be easy.

So the sound deadening wont make a significant difference huh? BTW im not running that much power to my subs ( 600 rms but rarely big bass hits as i listen to rock) my MAX out-put would be about 700 watts. my alt. wouldnt be able to produce that ya think?

I'll take your advice... I need to just look at the big picture and focus on getting a good ride rather than putting money and work into this car that has maybe 3 years left lol.

so i might just stick with a new set of comps & maybe the eq. suggestions?

thanks alot glasswolf, you are the man with the plan. You have the site that has that info on rear-fill and stuff right?

midbass drivers are typically found in a 3-way component set, and at 7" or 8" drivers. They are spec'ed to produce frequencies between teh subs and the midrange which in a 3-way set is usually a 3 to 4" driver

Before I recommend another set of speakers, what don't you like about the type R comps? What are you looking for?

sound deadening helps, sure, but it's money you could spend elsewhere for now with a limited budget.
600 watts.. 60 amperes.. yeah you may be alright on the stock electrical system.

the sound damping may help with midbass response in the doors. its worth a shot.

yeah that's my site. I just added some new stuff, too.

just read alot of your pages. very good stuff man. I need to look into resonance in sound systems/dc source. I understard inductive/capacitive reactance (& rlc circuits) for the most part. I could easily pick up on this stuff but I dont have the time or mental capacity right now as I am preperaing for my 01 electrical administrators license here in wa. I'm currently in school to become an electrician, at perry tech.

anyways. its really hard to say what I dont like about the type r's besides the ear piercing tweeturs. even have them set to -7 db. the speakers i test out at any audio store sound better no matter what due to the environment (correct?) not to mention they have been blown for a while and the integrity of the driver was probably flawed in its last few months of life leaving a negative impact lol. I understand the difference in watts (twice as loud as 5 watts = 50 watts. twice as loud as 50 = 500 etc.) and I know a silk tweet would probably give me highs that would be alot smoother.

basically i kind of want to test the waters i guess. If there is anything in that price range with similar power handling -that you would recommend, I would be interested in trying them. I have been checking out stuff on ebay listed as new and factory sealed. looked into a polk audio set they are advertising on crutchfield... looked at a jl audio set (I think)

or

http://www.ikesound.com/product-product_id/4656 (2 ohms wtf?)

http://www.ikesound.com/kicker_08ks602

http://www.ikesound.com/product-product_id/8479 (caught my eye, kinda steep)

http://www.ikesound.com/rockford_fosgate_t162s (space age tech.?)

I wanna stick with a 1" tweet. Im pretty sure my amp handles 2 ohm. but dont know what that changes. its a poweracoustic btw haha.

anyways let me know what you think

I understand entirely. The type R is an aggressive component set.
You want something smoother and more laid back.
Look at DynAudio or DLS. You might want to audition a set of Focal polyglass comps as well.
They would fit your ears better, I think.

I personally use DynAudio, and love them, but while they're very silky, they are also very sensitive to power because they use a first order filter network, and with the Q being that shallow, you don't feed them gobs of power on death metal CDs and expect them to like it.

what was that budget range?

for about $300 or less you should be able to find a really nice comp set.

well i have made my decision and i went with http://www.amazon.com/Cl-61a-25-Pro-Classic-Component-Speakers/dp/B001MSPI42

kinda skeptical. either way, sufficient power handling and im looking forward to the silk tweeters. overall i thought it was a good buy.

ok small problem... speakers came in and they dont match up to what they were claimed to be:

http://www.amazon.com/Cl-61a-25-Pro-Classic-Component-Speakers/dp/B001MSPI42

they APPEAR to be the CL-61i...


and thats as far as i got. the installation manual is incorect except the tw-25. HOW DO I EVEN KNOW IF THEY ARE TW-25?? cant find model # on the tweets... the midrange looks just like in the ctd site pic. the crossovers are the only for sure legit part because it says the # right on them.

anyways can someone that has alot of knowledge with cdt prodects help me out? what is the diff. from what i got and what they advertised. it seems to just be an older model. i dont know about this woofersetc. site...

CDT makes a wide range of component speakers. The CL61a set is a good set. Not amazing, but good and affordable. CDT gets recommended a lot as a good brand for people on tight budgets.
