iceman88 Posted June 21, 2007 Report Posted June 21, 2007 (edited) This one is going to be long, i'll try cut it as short as i can. Used to have 2 15's but now i have 4 12's, my thoery was i'd get louder. here is link to system HERE Now I dunno who can help but, when i used to have my 2 15's i could clearly hear it from outside the car but with the new 12's i got, in the Car its LOUD much Louder than the 2 15's how ever outside the car the 15's were louder. The 15's were areo ported. I had ports on the box, but local audio shop said the box is too small to be ported. He also said i have a bit more space than i should so i left the ports in and covered them up now its sealed again. The subs are pushing roughly 400rms each, amps are 787watts rms @ 4ohms, im doing 2 subs per amp. so roghly 400rms at each sub, they can take up to 1000rms each. I want to get louder, what can i do? i know i need to change the amps im working on tht at the moment, but for the time being what could i do? Also last note, they do this tuning thing, which they charge £30 for ($60) dollars and all they do is set the gain, Xover and Bassboost and also check ur settings on ur stereo. i personally think thts too much for like a 15 min job. Ask any questions Required plz! Box is 36" long - 15" depth (from start of boot to seats) and 21" High Guy at audio shop said i had just over 5Cubic ft air space. An help appricated plzzz! thank you.

AI James Posted June 21, 2007 Report Posted June 21, 2007 (edited) 6.5 cubes before sub displacement , doesnt seem wrong for sealed depending on subs Edited June 21, 2007 by James Quote
Coolwazabi Posted June 21, 2007 Report Posted June 21, 2007 6.5 cubes before port and sub displacement , yea the box is a little small for 4 12s x2... that is small... unless there like pyles... Quote
AI James Posted June 21, 2007 Report Posted June 21, 2007 and its louder outside ported because the ports directing the bass essentially into one direction. the sealed is just there pounding Quote
AI James Posted June 21, 2007 Report Posted June 21, 2007 i didnt read that it was sealed until after post so i edited Quote

AI James Posted June 21, 2007 Report Posted June 21, 2007 why do you want louder outside? thats just asking for trouble. only thing i can tell you is port it again and lose a sub. Quote
iceman88 Posted June 21, 2007 Author Report Posted June 21, 2007 why do you want louder outside? thats just asking for trouble.only thing i can tell you is port it again and lose a sub. LoL i just want it to be loud... lol any alternatives without losing a sub? i dont mind porting them again at its current stage, if need be i'll drill 2 more holes and put 2 more 3" ports. Quote
AI James Posted June 21, 2007 Report Posted June 21, 2007 subs wont have enough room in it if you port it Quote
iceman88 Posted June 21, 2007 Author Report Posted June 21, 2007 what could i do if i do keep them sealed? try and get more power? Quote
