So I recently decided to sell my old set up and buy new. My dilemma is that I can't decide wether I should go with 15 inch subs or 18's. This will be going in the back of a 2000 extended cab gmc Sierra. I'm going to be running a soundqubed 3500.1 on 2 subs for now at 12v. My plans are to buy 2 more and another amp by the end of summer and build a wall. I've decided on PSI platform 2 subs in box tuned to 30Hz because I love that low end bass. I need some input from someone on this.

Hello, I want to run 2 PSI platform 1 12s on 2k, my voltage does not dip below 12.8 so i will be getting right around rated. I have a screenshot to show the upgrades, Biggest box i can fit is 34"wide 15" tall and 23" in length I would like for the box to be tuned so i can play slowed bass songs about as low as 26hz if the small space i have will allow it I would like a slot port design with the subs and port on the same side (center port) Thanks for looking and hopefully you can help me out! -Mike-

Hello guys I am in need of some good advice, I am currently saving up for a new system, and it will consist of two PSI 10 inch subwoofers both at a dual 2 ohm load, and they both will be hooked up to separate amps. The amps I am pairing them with will be sundown saz2500d wired down to one ohm. So I will be hoping to push about 5k watts daily. I am going to get a yellow top optima for under the hood, not for sure which model i would need. I drive a 2012 Chevy Cruze 1LT with the pioneer upgraded sound system. The batteries I am going to put in the trunk will be xs power d3400's, I am putting two in there, not for sure if it is correct. So I was wondering if I should get an ho alt. and get the a yellow top optima and would I be fine with the two d3400's in the rear? Please help me out it would be greatly appreciated if anyone could. Thank you for reading this.

looking to start a junkyard of subs

Nothing really to this post i'm just proud of myself and wanted to show off my work ?

Hi everybody! This is my first build and I figured I would make a build log since I joined the forum. Here is the list of what's coming up up: - PSI Platform 2 HP w/ fancy colors *purchased* - Kenwood KDC-BT555U *purchased* - Sh**** Saturn *Purchased* - AQ2200d *Purchased* - Pink SHCA 1/0 *Puurchased* - Polk MM6501 Comps ....other stuff!!! stay tuned

I'm in search for a decent 12" sub preferably under $150 that can handle 500 watts or more. Thinking about getting a Soundqubed HDS2 or S3. Any other suggestions?

Hey everyone, i just sold my Sa-12. looking to get a build going, just got a new job, so ill have money, i have a hifonics hfi-1500d already. Ive been looking at several different subs for around 500, such as sundown z series, psi platform 3, DC Xl, etc. But then i was thinking about multiple subs, 2-4 sa-8's. Any suggestions on a setup with multiple subs to get loud. I want to be louder then my single sa-12 on 1k watts. i kind of want multiple subs. Please post any ideas you guys have, or any links of good subs for good prices, thanks in advance!

I want to make a box for my explorer for 2 platform 2 15s subs firing up and port to the back width between fenders is 40". thanks in advance

Welll, when i got my car i thought this was going to be easy, well...turns out NO ONE has an install video or pics or ANYTHING about 2005+ model Volvo S40's. SOOOO i AM the only person in the world who has made a video on it and pics on how to do it. Its all at our audio team channel. LABaudio502 Check us out on youtube. I would start off by saying this is NO WHERE close to being a clean install. Its messy as hell so dont judge on that. i will be redoing it next year when i have ALL of my final equipment. (Sometime in the fall) But, this was just the starter, temp. system i installed. Im thinking about doing a custom amp rack and box in the back but i cant think of any ideas. Comment if you have any deas! Thanks! First Box: T1 when i first got it in This was some UGLY wiring Car when it was stock The blown Fi SSD 12 i aquired! Punch Pro 6.5's Installed in doors Stockk Volvo door speakers, NOT BAD AT ALL! FTW http://www.youtube.c...ser/labaudio502

ok guys heres a couple pics of the truck. nothing great but it runs. dont i wish i still had my dc here is the box build. all wood cut all wood together making sure it fits i know non of the subs are the same. but its all i got. the truck came with a cheep sony headunit that i traded for the dual the silver cone/emblem and the concept. old amp new amp im borrowing i know wiring needs cleaned up. amp was tucked underneath box. but it got kinda hit. got knukoncept 8 gauge i had laying around. and a run of some unbranded 8 gauge. headunit

Hi so I thought I would share a box design I came up with and try to get some feedback and/or recommendations. This is for a single 15" PSI Platform 2 with HP option. I'm shooting for 4.5 ft^3 net with 65 in^2 slot port area. The box would be tuned to 33 hz and what I would do is make both of the sides of the port double baffle so that in the outer #/4" mdf baffle I could press and glue in threaded inserts. This would let me make and easy attachable port extension that would bring down tuning so that I can experiment and see what I like. If needed I can probably throw together a drawing and upload the picture if needed. This is my first build and I'm trying to make it a lasting good set-up. At first it will probably just be rear facing in by trunk but I plan to seal of my trunk fully and face the box into the cabin so that I don't have trunk rattles, I can use my trunk, and I can look at my bad-ass custom sub while I'm in the car. I'm open to any ideas. Thanks.

I'm curious to know, as far as LOWS go (23-30hz), what would be best position for a dual 18" enclosure's port? i love low notes but dont want to sacrifice the mid 30's either. To really FEEL the lows would having the port+subs forward be best? Also, what would a recommended tuning for the box be? 28hz? would there be a point in building a wall for 2 18s? appreciate any help guys.

Alrighty guys I am planning a trunk wall build based out of a 00 ford contour svt. I already have a 220 amp alternator dual big 3 on it, interstate batt up front, a kinetik 1200 blu and a kinetik 2400 in the back, 2 runs of 0g to the back batts (i don't drop under 13.8 usually), the amplifier is a soundstream t1.6000dl, i have 2 massive audio gtx 122 @ 2 ohm in a prefab (i know) its 1.8 per chamber at 35 hz it does pretty well for what it is but i wanna drop the amp down to .5 and i cant make a decision on what drivers i wanna get, my price range is 300 per sub (give or take) and i had quite a bit lined up but cant make a decision and I'm down to a couple now. soundqubed hdc3.1, psi lvl 2, dc level 3, massive audio hippoxl, ctsounds meso, dropin hz hotel, someone pleas persuade me into making the right decision!

Been breaking in a psi platform 2 18" for a few days. Now its blown and I'm sure it has to be a defect. Upgraded to 1800 watts. Running off a crescendo bc 2000. Batteries are two shuriken 4500's. No voltage problems what so ever. Straight out of the box the sub got warm at medium volume. Slight smell of adhesive/maybe coil? Day 2 Ran up the volume a bit higher. Played half an hour. No clipping I have indicators in the amp. Then it smoked not locked up but the coil is trash. Emailed the company twice now with no response. Funny they don't take calls. Is this sub garbage or what.

Does anyone know of any good Alpine Type R recones I could buy for my 2 12s? Ive heard PSI makes a good recone for it, but I dont know where to find them. Any Help would be much appreciated.

Im looking at getting 4 15" subs and building a Wall in my Tahoe, but not sure which brand is best for clean + low music. Im leaning towards 4 PSI Platform 2 15's, but now I've researched DC's Lv4 15s, as well as several of the Fi 15s. Call this stupid but I need a system that can play my favorite DECAF track (August Alsina - Downtown 36, 29, 27) as clean loud and low as possible; well, obviously not JUST that song, but I love it. Thanks guys.

Having some questions on a dual amp setup.. I'm wanting to run 2 Soundstream ta1.3000d on 2 PSi platform 3 15. The amps are rated: 3000 rms @ .5 ohm 2500 rms @ 1 ohm Subs are the dual 2 ohm direct connect PSi 15s rated at 3000 watts rms. I've never personally installed two amps before so my question is how would i run the rca's and then how to wire the voice coils to the amps? Any help is appreciated!

1 - 18" tc sounds lms ultra 5400 with psi recone. 2 - 18" psi passive radiators. Alright, so let me start by saying a few months ago I had got into contact with psi about my passive radiators really reaching their limits in terms of excursion.. they confirmed with me that things were alright and.. hey, they recommended 2 18" PR's would be good enough, so obviously I believed them & continued about my business.. Last week-ish, I heard some distortion with the reconed lms and got into contact again.. thinking it was blown and wanting a fix because i had told them it was going to receive 2400w rms.. they assured me it was able to handle the power and told me I was probably clipping and burnt it that way (I just I installed a new alt) and didnt retune the amp. Alrigjt, they offered me a discount of the subwoofer recone & i was gonna upgrade to the high exvursion PR's.. we started an order form and all that jazz.. Obviously, since I'm buying a new recone.. I might as well turn this one all the way up.. 10sec into the bass drop one of the PR's explode and rip apart. Now, these are out of warranty.. But shouldn't my email months back count for something?? When I said they were being stressed too much? So, I pull the sub, remove the magnet and find something surprising as well.. theres a bubble or void on the coil thats rubbing the motor. The copper wire isnt discolored or burnt. this doesn't look like a blown coil to me. Please correct me if I'm wrong, but this looks like a manufacturer defect that could be covered under warranty(I hopeeeee)
