Post your speaker set up.

[kingkilburn]

How would I go about doing a freq sweep? I understand why I should do it just not how.

[repda916]

what brand/type of speakers would you guys recommend for my vert? when the top is down i wat it to be clearly audible.
as of now im in the mids of my build so i have no front or rear speakers.

[kingkilburn]

It would seem to me that even with the top up quality sound out of a convertible would be hard to come by. I guess we'll see what Jeff has to say.

If you don't have a frequency generator function on your laptop or Iphone (iSweep is old, but works), you can record/download a PCM/WAVE (not MP3!!!!) file with a sweep on it.

Naturally, being able to control the start/end frequencies as well as the sweep range is awesome. Next you need a really sweet mic setup so you can graph your response. Then you do the same thing, but while you're driving at constant speed. Then you do it at many different speeds.

Then you realize that it's a 240sx and not a Bentley, and that it's never going to be perfect, and /wrists.

Top down you're going to need some power. It all depends on budget ~ the best bang for the buck to me is CDT, as I put together custom component systems with their parts for about half of what a comparable component setup costs from Focal, Rainbow, Dynaudio, Seas, MB Quart, etc.

Post up a budget and what you're willing to put up with sound-deadening-wise, and I'll give you an idea.

[kingkilburn]

I changed the phase of the sub and it's made quite a difference in the sound. It doesn't have quit the punch it did before but it feels like there is more sub bass(it's hard to explain). I think I need to play with the crossovers again.

It definitely got ride of the flat sounding kick drum though.


Update: I adjusted both crossovers down. That with swapping the phase of the sub has made it sound like a whole new system. Now I'm worried about cooking the amp. lol I'll see how that goes.

Thank you Jeff. Great advice.

I had the same Zapco 4ch amp and components in my last car (MIATA) and as was stated prior. it does take a lot of power to overcome the inherent flaws of a convertible but with the set up I used, it fukn rocked. and sound quality was great (with top up and not moving lol). Now, with the top down, all bets are off. Sound quality is out the window. But if you want to sound good and hear it at all, it needs to be loud at speed. And, it better be clean at those volumes and power levels or shit gets blown fast. At 50+ mph, you cant hear distortion that would normally kill a tweeter or woofer.

im runnind a pair of 5" idk brans in the front and a 10" infinity sub... just dont know wat to use for rears in my hatch

[ki_JDM_ds]

S13 Hatch

OEM Tape Deck + OEM Optional CD Deck
Alpine Type-R Front and Rear
eBay Speaker Adapters Front and Rear

Looking for some OEM Tweeters so I can sell my Front Apline Type-R coaxial's for some Alpine Type-R Components.

[imnotmatt1189]

S13 Coupe

Eclipse AVN30D Double Din
Unknown brand mismatching tweeters (came with the car)
Kenwood 6.5" Speakers (F)
Pioneer 4x6" Speakers (R)
Koiiler 4-Channel 400-Watt (not sure) Amplifier

My double din is outdated... runs kinda slow when going through the menu and such... and my speakers are cheapy. someday I want to redo my whole system with better quality stuff... but what i have does the job so it's at the very bottom of my priority list for my 240.

[240Z28]

s13 hatch
absolute atv860 hu
im runnind a pair of 5" idk brans in the front
hifonics 400w amp for the front speakers
10" infinity reference series sub
nitro 1000w amp for the sub... just dont know wat to use for rears in my hatch

[pornosquadz]

alpine cde-102 head unit
alpine type s 6.5 fronts and backs
alpine mrp-m2000 mono power amplifier
and one 15 inch alpine type r sub.

total cost $1000 all new from west coast audio authorize dealer(my cheap ass bargain with them)

does anyone think its worth it or what??????

[S13shaka]

thinking about the cdt audio EF-80 bc I cant find a good price on the EF-100, will the single 8" be loud enough?

[Nick_]

My budget setup

Alpine Iva-w205 ($250 used)
Alpine KTP-445 (micro amp - $99)
JL XR Series 6.5 - up front (gift)
Kicker 6.5 - rear deck (came with car)
Infinity Basslink - Refurb from infinity $135

Total: $485 - And for that price I think it sounds damnnnnn good. Ive had quite a few relatively high end systems in the past, and this is the best bang for the buck system ive built.

[musikjunkie]

does anybody know of and 12in sub boxes that are really compact or relatively small in size because i need one for my coupe and prefer to keep a spare and not have to hammer down anything just to make it it

[repda916]

shallow mount?

[Persona]

I made a box that fits a 10"(vertically mounted) with out covering the spare tire well. I'm 100% positive that I could make a 12" fit by angling the front of the box back. I posted pictures of my box a few pages back.

If you are willing to build a box it shouldn't be to hard to make something work.

Haha sweet I'm not the only one, i have some $2 dollarama speakers hooked up to my ipod, i can barely hear them over my exhuast. Chicks love it

[kingkilburn]

What the chicks dig is the rumble of the bass in their nethers from a good sub while listening to dubstep/electro. lol

[crozzover69]

I have a 1990 240sx coupe and some aight Pioneer headunit.
On the sides, in the quarter panels I have some 6x9 Infinity Kappa 693.9I
speakers.

I'm wondering, How can fit an Infinity KAPPA perfect 6.1 component
system in my front passanger doors. I know how to install
the tweeters but was curious about the mids and was
wondering if anyone else had experience with this set up.
I mean Is this totally ludacris?
I already have a 6 1/2 adapter but am unsure of the speakers mounting
depth. The website says the mounting depth is 2 3/4 inches.
