I have a DC lvl 4 m2 18 d2 and an american bass hd 3500. bout 1200rms clean. the sub takes 1400 and its underrated. on dc's site they reccomend a 6 cube box. how to i know how much to compensate for the lesser power?

I just put in a new box in my 1999 jeep grand cherokee and I reattached the back battery, In doing so I noticed my voltage is at an average of 12.6 with little bass. My voltage is going crazy and im not sure what is going on. Normally at full tilt on rock, the voltage plays at 12.8, But now its at 12.2...... My Interior lights are now feeling the power drops and dimming everytime a bass note hits.....as before it wasnt doing that......any ideas?? My alternator is working i had it checked today..... Also might i add that with the bass off my voltage goes from 13.6- to 12.8....with no bass...only mids and highs......wtf?!

The other day I was in the drive through at Wendy's and my mids and highs sounded odd so I turned the subs off and cranked the volume higher than I ever listen to my system to try and pin point it. After I got my food I turned the subs back on with the headunit still paused without turning it down Lawl...so I unpause it and KABLOOMBANGNASTYSHITBRIXLOUD....I scared the fuck out of myself and my girl wouldn't talk to me for a while lol...has anybody else had a shitbrix bass moment?

Hey guys... i just went out and bought a new Jig Saw. Mine decided to blow up earlier today while i was working on my new box.... pissed me off cause i would have had it done by now but no it had to die. It was already pretty f'ed up but oh well here is some pics of my new Black and Decker jig saw.

Hi Guys, Having some issues and need some help. I recently found a Audison bit one at $178 and the price was really attractive. The down side is it does not come with the DRC, CD and the USB cable.My worry is with out the DRC would it be convenient unless i don't change settings?CD - i manage to download the software online but will it be able to use?USB - is this the normal USB which we can find in stores?Would appreciate your help to leave some comment and to clear my doubt.Thank you in advance.

My friend has an 02 Mustang GT convertible. He wants to cram a BTL 15" inside. His rear seats do not fold down. The question is...If his seats were not folded down would that affect the bass significantly or only just a little bit. He was thinking of taking out the rear seats but that would expose the convertible motor and stuff. The first task is to see if a 4.0cuft box would even fit back there... Thanks for any help.

So come January ill have all the bits n pieces for my build. What are some things I could do build wise that would make it sound that much better? I read somewhere about firing the sub forward and sealing off the trunk. what is this and what are the advantages? just looking for some ideas of how to squeeze every bit I can from this build. thanks in advance.

Whats the easiest way to hook up your car audio amplifier to a home stereo? I imagine it involves a $200 converter or something but just fill me in a little.

Hey guys. Ok the is my dilemma. Ihave 2 JBL gti mkii 10" and 2 amps. Ihave fused the voice coils together. Well I assume that's what I've done. One reads at 3.5 ohms and one at 7 ohm. So what I am asking is can I link the subs together to even out the ohm load and then run the amps in parallel. And if so how would I run my speaker wire. I really miss my good out put but I don't want to cook anything and have no system. Please help

Is there a way to keep my steering wheel controls with a new head unit in a infinity g37s? Also how difficult will it be and what head unit would let me to do so? (preferably one with navigation)

Hi all, it’s been a while and I want to try SSA again. Had an XCON 15 for 3 years then sold it. At the moment I currently own two Stereo Integrity "SQL" 15, single 15 Adire Brahma, and two 10s RF power T1. I saw the Zcon 12 on SSA website and wanted to see them in action but couldn’t find any vids on YouTube for that model. Anyone in here own that newer model and what are your thoughts on the SQ. I’m mainly looking for a clean SQ driver that can get brutal when want to and doesn’t sound distorted/mechanical noise.

I have a powerbass xs15d2 and I've been hearing a rattle. So I inspect the sub and the basket is loose from the upper plate. This would be a defect not user error correct? Also the sub still plays fine and don't rattle while playing music parked but only rattles when I hit a bump or dip in the road. Should I use it till it get replaced? Any suggestion are appreciated.

Hi Guys, I think some people from SMD might have posted here about this already. Im the one behind the app and proud to get something out there finally Android app for box tuning is finally here...FREE... This is Beta still and can still be buggy. I am constantly working on updates and fixes and new features though. The app is for android 2.1 - 15+ , so hard to test when developing. Currently the app allows to calculate box specs and there is a total resistance calculator. The app can be found by searching "box tune calculator" and can also be viewed here My app If you have any requests of what features you want, please let me know and i can add them. if there are any cr…

(4) 18" mach 5 audio MJ subs all single 4 ohm 2. power it with (2) 2200 power acoustik 2 channel amps note: might get the 2600 3. kicker 4 gauge wire kit 4. custom sealed box with subs facing up this will be going into a 2002 escalade and i have the 3rd row seat took out and my last set-up was a kicker 1200.1 with a 15 inch L7 but do u think if i go with this setup it would out pump (2) 15 inch L7 subs? i know these are SQ subs but they should get very loud knowing im getting 4 of them

I am looking to sell my current setup to upgrade I currently have a Cadence ZRS-8 amplifier (1500 rms @ 1 ohm, 750 @ 2 ohm), and a 12" RD Alpha V.2 in a 2.3 cube box tuned to 33hz. Along with my 6.5" Polk Audio DB615s (slim fit), Infinity Reference 9623i 6x9's, and Pioneer deh-p3900mp H/U. What do you guys think my setup is worth if I can sell it?

Ok, i hooked up a friends new amp, a 10001, to his q. it sounded really good for about a week then started making like a rattling noise and i cant figure out what it is. i have the settings on the amp to gain half and the crossover at 50. does anyone know why it might have a rattling noice. its not the box. im almost positive its the subwoofer.

Just donated my 2 ssa icon 12's to my nephew for his first ever system. Building a new system for my f150 crew cab, debating one evil 15 or 4 ssa f8l's. Space doesn't matter and I have a few amps to choose from in my collection. Just curious if anyone is running either of these setups and can add any input. Thanks in advance

i am new at this whole car audio thing, so i need some advice and guidance. i was ordnally looking into jl w7 12 inch with 1000/1 amps but then someone told me they were over priced and not that great. so i looked into FI's. first off, i was looking into the BTL's 15 inch (probably n2). im not sure if i should get one or two, im not sure if one is gonna cut it. but i also need some advice on good amps, i know which wire kit im getting and i know the high output alternator im getting. and im a little confused on what some of the ohm and what ever do. what does ohm mean and what do they do? i have a choice of either dual 1 or 2. and all i want is someone to point me in the …

Hey guys! got another topic about a new set-up idea i'm looking at Current set-up is an 18" BL on a JBL BP1200.1 amplifier Currently though, i'm looking at picking up another BP1200.1 for a total of 2. this means I would start changing around my subs then. Here's where i'll give you the info and you try to help me decide Limitations: Each BP puts out 1200 watts @ 2 ohms. I'll have two of them and they're not strappable so it'll be two subs i'm looking at. I have around 5.8 cubes of space to play with. Max sub size I can fit in terms of still being able to get the box in the trunk are 2 15's. I'm leaning more towards 12's though just because then i can actually give them a…
