Hey guys I stopped by a local car audio shop today and talked with a salesmen for almost an hour. 90% of their products are Kenwood and he swears by them. He had a lot to say and I was just wondering if it was true because there were some things I have never heard. He said that running an amp at 1 ohm is a bad idea because the sound quality drops significantly. He also said that you should spend more on your box than on your subs because the box is responsible for 75% of your bass. He also had very little good to say about Fi or sundown but that scosche is a very well respected for their sub woofers and amps I don't know if any of it is true or not but if you guys have an…

Hey guys, im currently redoing my build. I plan on doing two 8" sundown neo pro along with a good tweeter in each door as well as maybe glassing a 4" component set in the pillars. Also gonna be running 4 DC 15" XL's, but im looking now at a processor. This is my first big build like this and im new to this whole processor thing so be gentle please haha. My headunit is the pioneer Avic-Z130BT if that matters. I just want to clean things up a bit and do everything the right way so can someone suggest what i need to do and just exactly what a processor will do in my setup?

Running a 10" JL (300 RMS) on an Alpine amp at 150 RMS at 4 ohms and I just fried it. Same happened to my last 10" Punch. I thought i had the sub matched perfectly to my amp but obviously I am doing something wrong. Anyone know of any good instructional material I can read to educate myself before I waste any more money? I wanted to upgrade my sub and amp but not if I am going to just ruin another driver. I do listen with the bass boost up and at high volume, I am definitely hard on my subs, but thats why I was careful not to over power this one. What else could I be doing wrong? HELP!

Ok, I have like 3 8'x16'' long boards of 7 layer plywood. i am going to make a box 40x12x12 for two 10 TC7s. Should I go buy MDF or would the 7 layer plywood work just as well? the box will be ported using 3' big 14'' long areo ports.

theres a kinda new song out called Black Mags by: The Cool Kids....i was wondering if there's anybody that wouldn't mind making a video playing this song. ive only heard it on my computer sound system, and it seems like it beats pretty hard and low... i just want to hear what it sounds like in a car wit a nice sound system....anybody want to do it? thanks guys

Today i hooked an amp up to my front stage. Sounds great, except for the buzzing i can hear when music is paused. My amp for the front stage is grounded the same way my amp for my sub is, and yet i still get buzzing. It's kind of a high pitched buzzing, with really high pitched sounds mixed in that kind of fluctuate. It only buzzes when there's a source though. Once i plug my iphone into the head unit, the buzzing starts. And using the touch screen on the iphone, such as scrolling, makes a sound. I can hear it whenever i scroll with the screen. My head unit can't be the problem. I used to have a low rumble with my sub (like this buzzing) and i fixed the ground on my hea…

I am looking into the possible carrer of building speakers and audio equipment. Nick, Jake, Where did you guys go to school after high school to learn how to do all this audio greatness. I dont have a clue where to start looking. I think maybe electrical engineering, but maybe there is a specialty school or something. Let me know anything would be appreciated. Thanks, Steve

I haven't installed anything in a year, but my buddy needs an experienced mind. He's got an eighth gen civic si, and would like to replace the stock, 8" sub. He's up for complete removal, since he knows he won't get a true subwoofer-type sound without an enclosure or sealing the trunk. Now, it needs to be extremely stealth (carpeted box, all black, tucked in the corner, no visible wires anywhere). He's dead-set on a type-r and an alpine 500W amp to match. I'll set him up with some black knu wiring, too. Two options I've thought of for the box: -Sealed, cut to the shape of the rear, side of the trunk, carpeted, with a grille. -bandpass, carpeted, ported up and to…

just kinda curious what yall use to mount your subs, ive used mostly just wood screws but was wondering what other recommendations were? Thanks

I keep telling a buddy of mine to go with Fi instead of a Circuit City MTX Jack Hammer Box with 2 12" subs. Please give me some advice or videos for me to give him. Fi BL 15" vs 2 12" Jackhammer series MTX subs. I am giving him my Hifonics Bx1606d amp so he has power and he has room for both. Any advice would be great. If you have a 15" Fi BL vid please show it off. Thanks.

well my set up is in the sig. i played the three6 mofia song late night tip (slowed down) and my amp cuts out. i can play any other song same vol and every thing just asking if some one knows y it dose that.

I have 10 polk audio mm651um ,1 300 watt 10inch soundstream sub, deck is 50x4 watt ,and 1 100x4 sony amp do I have enough power to maximize speakers without doing any damage if so how do I hook them all up. Thanks for any info.

If anyone decides to go with FI - Your choosing to have the BEST. just my2cents Then again there havn't been to many top stereo's to listen to music on at SBN in the last 10 years. Some but not alot. FI showed up with the QUAD all day and I, an oldskooler who thought SPL had killed our sport, have witnessed the second coming. I was very excited to say the least at the best Daytona SBN's in over 10 years thanks to everyone reppin FI. You made the difference. It woulda been the same old thing - we find that one truck hear it walk around until we're back at the same truck. FI brought back the old days where you actually have something to do all day besides charge bat…

This is the problem... I ordered about 6 weeks ago 2 Kinetik Audio HC1800 batteries on Ebay at IndoAudio (yes, my own stupid mistake). And since then I didn't receive any batteries. Now I am looking to get my cash back from Paypal / Ebay. Anyways, I still need 2 good brand batteries, which can feed my amplifiers. Amplifiers in use (or soon to be used): - 2x (strapped) SAZ-1500D - 1x SAX-100.4 (bridged) What brands (and preferably what types) can you recommend. I am on limited space in my trunk for the batteries; so smaller in size is good, but bigger in size is a no go! Thanks for your help. /edit I currently own 1 Optima Yellow Top in my current car hifi configuration, b…

This seemed like an appropriate place to put this, sorry if its not. I would like to get recommendations on good installers in the central/north central Ohio area. I want to talk to someone about my custom glass enclosure I plan to build, see how feasible it is or possibly have the shop do it if I think it's too much for me to handle. I really want someone who can teach a bit here. Not just looking to make a sale, someone I can talk to. Any ideas?

I have a couple questions about setting the gain, and the settings I should be using on my head unit. My setup is a IDA-x100 headunit from alpine. (Pre-Amp is 2volts) My subwoofer is an 15" Q, and amp is a SAE-1200 Sundown. On my headunit, I heard that the subwoofer level should be set to full, 15. But I didn't know what to set the base level at, so I just set it to full, 8. Then I tuned it to 36volts using a dmm, (Thats what the tuning instruction sheet that came with the amp said to tune it too) It sounded good, but I feel with that much power, I should be getting it a little louder. So I put the bass to 0 on the headunit, but then I could turn the amps gain up to maxim…

so when i was growing up.. im 24 now so what ever... anyway everyone that had a bad ass audio set up owned a epicenter, so of course when i started gettin biger in the game..( ya know a the big 3 with 2 batts, 2 jl 500/1s 2 w6 15s and 4 jl w3 12's).. i got a epic center.. i but it in and it sucked! i donno if i just could never get my stuff tuned right with it but any song with an 808 beat sounded like trash..... but any old school song like i donno old from the 92 or 93... those songs were at there best more beat more knock then ever before. but now! i have 2 15 FI bls fully loaded, 3 yellow tops the big three and a sun down 3000 on the way....... whats your take..…

When a person puts 4 12's rather than 2 15's what are there goals? What are they trying to get out of it?

I will be soon upgrading some components in my system. I have a new SAZ-1500d v.2 that will be paired up with an Xcon 12. I will also be getting a DC Power 180 amp alternator and will do the Big 3 also. I just have some questions. I haven't ever worked on a system dealing with this much power, and just want to make sure I have everything that I need. First, my current setup is a dual amp setup using Rockford 1000-1bd amp and alpine pdx-4.100. I used a 1 Farad capacitor (Ya, I know ) basically as a distrubution block for those amps. Electrical is stock. The capacitor will go away when I upgrade, so I have been looking at distribution blocks. I know I will need a…

I know a lot of people have built their own sub boxes or have had one custom done for their needs. For the people that have built their own. How hard would you say it is? also are there any diy's out there?
