Flat Side Of Glassed Enclosure

[djXternal 10+ year member]

Ok im gonna be fiberglassing and enclosure for 2 JL 10w0's, and the rear of the enclosure is just going to be a flatwall... would it be best to just use MDF for that flat part and attach fiberglass to that, or to make it a one piece fiberglass enclosure with the flatside glassed as well?

I'd use MDF... Cheap and easy...

Use MDF. MDF is stronger than 'glass when flat. 'Glasses strength advantage is only when curved.

alright then what is the best way to attache the two together?

Yes. But just to clarify.....you staple the 'glass mat to the MDF before resin is applied to the 'glass mat.

Sorry, just wanted to make sure you weren't trying to staple hardened 'glass to the MDF.

Thats only 63 wrms per sub, id send those atleast 150wrms each.

hmmmm... If i wire them like the first pic on this page (parrallel i think it is)... wouldnt they be getting 125W each?

and if im completely wrong, then what would a good amp be?

You can add ridges to flat panels to add a bit of strenght... Kinda like they do in flat steel panels on cars (ie floor pans)..

You can wire those subs to 1, 4, or 8 ohm, and im gunna say im sure that amp isnt 1 ohm stable so you would be stuck wiring them seperate at 4 ohms each and therefore losing half your power from the amp, then it has to split that half between the two subs giving you only 62 watts per sub.

alright so i need to find an amp with power of 300W RMS x 1 @ 4 Ohm? and that would give me 150W to both subs? how would i wire the subs together with the amp in that setup?

 

[Moe Lester 10+ year member]

are the subs single 4 ohm? if so, 250w @ 2 ohm will be 125w per sub
