A friend of mine has just sold his 3 sets of Focal 6.5", and he wants to run P A speakers to be louder. He runs an Infinity amp (4 x 125 w rms @ 4 Ohms) and don't want to change amp or to add one more. He was going to get Beyma speakers (the pro series I think) but he wants to know what else can he get ? 2 sets of 6.5" speakers for the front doors. Nothing in the rear, except his 18" Soundstream XXX in a big ported box. He want something that can be loud but with good midbass. The tweeters will be a set of Beyma available locally: they get sooo loud ! He looked at the sundown neo pro, but never listenend to them. Is it a good choice over the Beyma ? What other options can…

lvl4 18" with lvl 5 coil http://www.youtube.com/watch?v=xXtzQCCzTSw http://www.youtube.com/watch?v=Ug3RnLiGn-U

Well I think this is the set I am gonna get for my car. I am getting them for the FRONTS only. Will they get pretty loud and still have decent quality. I wasnt lookin to spend to much money and these seem to be pretty good. http://cgi.ebay.com/BOSTON-ACOUSTICS-SL60-...1QQcmdZViewItem

i am trying to decide between the dc lv4-12 or the new IA death row 12 i am thinking about using a hellboy box or have one custom buil by brian any info would be helpful

which would you choose for a ported box? amp would be a US AMPS MD1D (1200w RMS @ 1 ohm).

Just asking because the port would be to close to the hatch. Any opinions?

been digging in on the system some and have discovered the original plans of the sls 8" isnt going to work just due to the sheer diameter. Need some recomendations on a badass 7" midbass driver to be mounted IB in the front doors with a max depth of 4". These will be running active with Seas W12CY-001 4.5's and Seas 27TFFNC/G tweets mounted in kick pods. looking in the area of 200-250 per driver to be the high end. Front stage is to be powered off 2 Sundown 100.4's to allow for flexibility of more power to the 7's by bridging the one running them for more output if needed. Thanks in Advance

http://www.soundstream.com/subwoofers-ri.htm Look very interesting. Wouldn't mind listening to some, and maybe seeing what their pricetage is.

first off i havent been on this forum in a while but im looking for a new setup soon and getting back into the scene. so anyway i sold my friend my fi bl 15 in a 3.4 cu.ft. box tuned to i think 30hz. i had it in the trunk of my 95 civic running off of a sundown sae-1200D and it sounded good and hit pretty low. once i installed it in my friends late model malibu it was running off a sundown saz-1000D it honestly didnt sound to good at all. so he is looking for more and he wants 2 15's but i told him its not gonna fit, so i suggested a single fi btl n2 12 or maybe 2 bl 12's, hes not rich so his buget isnt to big. any suggestions would be great thanks!

This is a new one to me. So it got cold here and I turned my car stereo on about a week ago. The right midrange in the kick sterted to make a static/crackling sound. I immediatly turned the radio off until I could check it over. I checked my wiring and everything is secure. I turned the radio back on and the problem is not there anymore. The speaker then worked and no static. Two weeks go by and its randomly doing it again. I am at a loss. Ive checked everything but the impedance of the driver. Who knows maybe its on its death bed. Squeak, you do warranties? lawl! J/K I love these Coustic speakers and really dont want to go through the hassle of finding another …

Anyone know what the cutout is for the 22" baskets?

I just built this box for 2 first gen dcon 12's but cant figure out the cuft3. Need help. Thanks for any and all replys

I'm looking into redoing my system and I am having a tough time choosing. What would be the best combination for a daily setup no comps just loud daily: (2) 15" AA Havocs 320 Amp alternator 1 Sundown 3000d 1 kinetik 2200 or 2400 or (2) 15" Fully loaded bl's 320 Amp alternator 1 Sundown 3000d 1 kinetik 2200 or 2400 or (2) 15" Fully loaded btl's 320 Amp alternator 1 Sundown 3000d upgrading to 2 later 1 kinetik 2400

I just purchased a pair of SEAS tweets and was wondering if I wrapped them with grill cloth over the metal mesh grill if this would affect the sound.

As the topic says I just got my first SD12 and had 2 questions First: rms is 500 watts is that total or per coil? Second: do I have to break the sub in or just fire it up and go to town? Thx for the input guys

At the moment i have a JBL GTO 1514. But thats not good enough (for me) so i was thinking of getting 2x12 inch woofers. They have many deals and brand names i haven't ever heard. Like: BassX BW-500X Boschmann V1240XYB (my friend has one, sounds pretty good) Mystery MJS 12F Ground Zero GZTW 30T (i have heard something about that) Fusion EN-SW12ES Anyone can tell something about these or has any suggestions ?

what do you think of this as a midbass silver flute very flat from 50-500hz incredible senstivity and i cant complain about the price.

My friend has an older Mag and I have a newer one. I wsa thinking of getting the older one and running it with the new one. Will this cause a problem, especially if they're in a common chamber box? Also how much power will it need...how does a Concept CC-D1200 sound?

Looking towards the Audioque SD2.5's.. 2 subs that will be a very loud daily driver/competition Street B quality off an ED 9.1 1350-1500watts @1ohm Any other suggestions? looking for $350 or less

So I'm thinking of getting the Lvl 4 12" for my single cab and have designed this Downfiring Enclosure with Port up enclosure. Box is 2.00 Cu. Ft. tuned to 35 Hz. (After Wood & Port Displacement).26 Sq Inches of Port, 21 inches in length. The Website says it recommends 1.5^3 Ported and 2.0^3 For SPL. Does this box look alright.?? Do you guys think 2 Cubes is enough?(If not I think I can squeeze out more space somewhere.) I also wanted to know what the sub displacement is for the Level 4 12"? Thanks, Danny

I am Looking to buy Fusion PP-FR6920 and i was just wondering if anyone has dealt with fusion or knows if there a quality company?

I want these: http://cdtstore.com/cl_series/cl60.htm Do I have to buy 2 sets? I'm a little confused as to how to purchase this. If I choose quantity of 1, does that mean I just get 1 6.5, tweeter and xover? So would I have to choose a quantity of 2?

Rec'd my Xcon 10D2 back in October and finally got the car install done yesterday and all I can say is ....Damn . I have the Xcon in a 1.2cuft^3 sealed box and it sounds amazing. I know it'll need some time to break in, but this little monster sounds tits . I replaced a Phoenix Gold TIElite12D to reduce some weight, but the Xcon actually weighs more than the Elite and seems to be more efficient as I was running the ELite off a PG TI1200.1 and the Xcon is currently runnin' off a JL Audio 500/1v2. Great sub for the money and couldn't be happier, thanx again SSA.

I have an 01 dodge ram extended cab and I am debating on wether I should wall it with 2 18 BTL's or do a 4th order blowthrough. im leaning more towards the blowthrough for the comfort level but im afraid to cut!!! plus i have heard a few 4th order blowthroughs but none in a cabin space as big as mine (only in minis). What do i do
