IKnowImLost224 Posted November 26, 2011 Report Posted November 26, 2011 (edited) I have 2 12" Alpine Type X subs powered by a Power Acoustik BAMF 4000/1 in a 2001 Malibu. I built a box to Alpines listed specs and I dont think they sound nearly as loud as they should. To me, the 1" width of the port looks small but I am not really familiar with box building and what adjustments can be made to get specific tuning and how to get more SPL. I was hoping that maybe someone has built a box to make these sound good and can help me out some! I attached a pic so you can see what I did, I know its nothing pretty. Thank you Edited November 26, 2011 by IKnowImLost224 Quote
TeamHT Posted November 26, 2011 Report Posted November 26, 2011 Well, the other thing is amp choice and possible wiring. I would definitely redo the box. Would you be keeping that amp or upgrading? Quote Tell me...does this smell like chloroform to you?
IKnowImLost224 Posted November 26, 2011 Author Report Posted November 26, 2011 I would be keeping the amp. I have the subs wired to 1 ohm and the amp bridged Quote
miniSPLlancer Posted November 26, 2011 Report Posted November 26, 2011 (edited) 12-16sq in of port per ft3, another thing to remember, you can get these to be really loud but they are SQ subs. To get them be a little louder I would do 1.5-1.75 per with a 3" common port Tuned to 32-35hz Edited November 26, 2011 by miniSPLlancer Quote 2011 Mitsubishi OutlanderSony 712 Soundqubed HDS208 Alpine MRV-M500 Transmission line enclosure Soundqubed wiring Knu rca XS Power battery CNF terminals
IKnowImLost224 Posted November 26, 2011 Author Report Posted November 26, 2011 Now with them being SQ subs and if that was the route I was going, would it be optimal to put them in a sealed enclosure? Quote

Roger that...or a 4th order, now that is an idea to achieve clean bass and still hit them lows!

I don't know the basics of port tuning or how to achieve the frequency i want. Quote

Lol, I probably sound stupid but I have heard of a 4th order bandpass box, have no clue what it is or how to build one Quote
