Sonic Electronix Website Down??
ear2ear replied to Tarball's topic in Sonic Electronix - Great Selection Great Prices
Me too. Blank screen - just sits there... -
Admittedly my first post was way off - I thought it might be a trick question. Since it's not (a trick), aren't we just talking semantics? I hope a video can show otherwise. Car on/car off - yes there will be a different return path, but aren't we just arguing whether it's the: a) SOURCE of greatest voltage potential or PATH to the source? In the house wiring example what do you want to call ground/common? Is it the: a) earth = (alternator) the point we access the earth - 6ft copper rod = (alternator case - car running) c) all the common house wiring = (chassis) What's the difference? You're either talking about the source or the path to the source. edit: shut off emoticons

Sound Deadening help Please
ear2ear replied to viper1315's topic in Second Skin Sound Deadening and Automotive Insulation!
Constraint Layer Dampers do not just remove "rattles". It reduces panel resonance. A rattle is where 2 pieces tough/rub/click/slap together. Road noise and other noise is transmitted through the sheetmetal that you don't even realize. My brand new truck didn't have any "rattles", but applying a layer of damp pro sure made a difference. It took road noise from a SHSHSH down to a shshshsh. Now my audio has less to compete with. -
fuse block fire!!! pics up

^^^What he said. How long is that 4ga run? Also do a quick check on the ground for that amp. Clean shiny metal - no corrosion. -
Are those all inside port dimensions? Some of them do not add up.

This is going in the trunk, not the back seat. Since you asked for dims: 17" tall, 37.5" wide, 39" deep. Yes, i've measured. It will fit. My bad - reading > me So even with enough room in the trunk, there's not enough room on the baffle for a port. Anyway, what I meant originally was measure the current box and these guys might tell you why it sounds the way it does. -

12cu ft in the back seat of a Jetta? You should measure it and the port and post your dimensions here. -
how do i get a straight inner port cut ?
ear2ear replied to fx4trucker's topic in Subwoofers / Enclosures
Have access to a table saw? Plunge cuts make this really easy. Then clean up the corners with a jig saw. This is a window brace, but same concept: -
Well your dimensions give you 8.75 gross. I would work backwards from there. Definately not room for 4 12s or 2 15s really.

I ran some numbers through Torres earlier and sketched a baffle in CAD. Assuming 15.5" O.D. woofers and single layer 3/4" all arround. You can barely fit a 15" x 15" square port on a diamond (rotated 45 deg.) That's 225 sq in. The problem is the length of the port. It's length is not much less than the required depth of the box for your 16 cubes. And you would need minimum 15" clear behind it to the back. So, over half the port length would have to be external.

Yeah, seems wierd to have it in the front. But it's a progression of things. I was trying to do the back, but it was screwing with my port area & also I could never get to the fuses. I may build a center console that flows into the battery area. For now I'll make a nice cover. I hear ya. I already filled up the extra battery spot under the hood though.

New box design. It's actually 2" shorter than the sealed box, but takes up the entire rear.

Well, thanks for all the kind words and condolences. That thing met all my design critera except being loud. One of the things I wanted was to be below the window line. It was already borderline so raising it wasn't an option. Cutting some of the false floor out was an option, but so much crap was integrated underneath. Maybe gain a bit, but never what it should be. So yeah, I'm well into my new ported box. 9 cubes net 138 sq in @ 33ish Hz subs up / ports up Anybody see any real problems with those specs? It's another intricate box, but at least a simple concept. Old T1 12's getting ~800 watts a piece. rap, dubstep, top 40, a lil country Thanks
