ImLow78 Posted September 15, 2008 Report Share Posted September 15, 2008 Ok guys this is the deal. I had a guy that owed me some cash. So instead of him paying me he gave me his subs (JL 15w0's 8ohms) in a sealed enclosure. So now that the day of me finally getting the bug to finish the system in the Tahoe and I'm thinking about building a ported box for my 2 15's. Here is the dimensions of the box & ports. External dimensions are W=40 3/4" X H=18 1/4" X D= 24". It will have one port in each enclosure (I'm separating the box in half so it will have two independent boxes in one with a dividing wall, hints the 3/4" addition in the width measurement for the box). The port dimensions will be I.D=5" x L= 15 1/16". So what will be the tuning frequency for this enclosure. I will be powering these subs with a Alpine PDX-1.1000. I'm going to wire them in series to get a 4ohm load. Also guys I know that these are not the best subs! trust me if I had the cash I would be buying some TC sound subs and I hope to buys some of them when I get back on my feet. So please don't bust my chops to bad of using these subs. Its all I have and can afford at this time in my life. Thanks guys for the help.

EricM9104 Posted September 15, 2008 Report Share Posted September 15, 2008 Umm... If you wired the subs in series, you'd get a 16ohm load, not 4. If you were to wire them in parallel, you'd get a 4ohm load. Tuning frequency, no clue. Wouldn't 1kw RMS be too much for those subs anyways? 2015 Honda Civic LX 4dr | 24k miles Stock H/U and mids/highs Power Acoustik GW3-12" D2 Sub HiFonics BXX1200.1D @ 1ohm Random 2.5^3' dual ported box NVX LOC Stinger wiring throughout 1977 Chevy SWB Cammed 350 Dual exhaust Cheap Wish stereo Link to comment Share on other sites More sharing options...

I thought I'd try and keep the gains down for now.

ImLow78 Posted September 15, 2008 Author Report Share Posted September 15, 2008 I've also been kicking around the thought of doing a Isobaric bandpass box. (I know that most people are against this type of box, thats why I said kicking it around). Also if anyone has the dimensions of what I would need to do a enclosure like this with port dimensions would be greatly appreciated!
