i'm in the wrong damn business... i think i'm gonna go to snake-oil school! BWAHAHAHA 10 bux for a pair of non-polarized cheap-ass 50 øF electrolytic caps... !!! also, those frequencies seem WAY high... what frequencies are you trying to block? are you using an amp? if so, why not set the HP crossover on the amp? way better than a "Bass Blocker", with it's PFM description... (and i wish there was a way to let everybody HEAR my sarcasm...)

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

buy a deck with highpass crossovers if not an amp

you should always start with the deck when building a system

that's your source!

lookie here  https://www.the12volt.com/caraudio/cross4ohm.asp  , ,thats a chart for helping you decide, , you probably would want something in the 150hz- 200hz range, ,,then you can get some non-polarized caps for $5 all around at an electronics shop.

the deck is a pioneer deck, not bad...im am just rewiring a friends car because the person who installed it had no clue what they were doing...

i am aiming for 150hz, which caps should i be getting? i am not running this off of a amp, just directly off the deck without a highpass crossover.

the chart is a little confusing so i'm still not sure what to get....

150Hz high pass capacitor...for 1st order 6db/octave:  265 microfarads.  Here's one you can see shown at https://www.partsexpress.com/pe/pshowdetl.cfm?&PartNumber=027-370&DID=7, or this one to filter out below 125 Hz.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

as an electronics guy i can tell you that the cost of non-polarized caps rises exponentially with the value ( uf )....

i can buy a bag full of 10 uf caps for a buck or two.....

but just try to buy a 400 or 500 or 600 uf non-polarized cap... they cost 10-15 bucks each !!!

in many cases i cant even buy them locally and am forced to buy from a couple thousand miles away or buy them from the car audio accessories suppliers.... of course i am stuck halfway between the Pacific and the Atlantic oceans and selections here aren't the best......

Yep, i bought a couple caps (non-polarized) from a local shop, to block bass from two front door 6X8s in a f-150 and i wound up paying $14 for two 260uF caps....So the ones crutchfield has aren't that bad in price....They will work just as well as any crossover to block lows if u get the right value capacitor....150Hz is about right....the X-over on my head unit is a 125Hz HPF and it works just the same as the bass blockers i put in for the dude with the 6X8s.
