MTMustang7 Posted August 24, 2011 Report Share Posted August 24, 2011 I've been looking at some of your posts about polyfill and I'm wondering if it might work in my application. It seems like it's mainly used in sealed boxes but I've seen some in ported. I'm trying to improve my numbers and wonder if it's worth trying. The box made with 3/4 birch and is 14H x 32W x 26D and the front is doubled. The port is 5 1/2W x 12 1/2H but I don't remember how long it is. The port is in the middle of the box and makes a T at the end. I think it was tuned to about 36hz but I can't be positive without knowing the length of the port. Also the box is firing into the car and I still need to seal it off.

will77530 Posted August 28, 2011 Report Share Posted August 28, 2011 Today i fully hooked up my system. EVERYTHING IS BACK TO WORKING. Except my amp... It plays bass and very well... but my gain has to be maxed along with the gain knob maxed to even hear it being ssorta loud. Everything is maxed and its still not loud enough where i think it should be... Also Before my amp even plays bass the gain has to be close to 3/4 and there its even quiet. The sub and amp is brand new No matter how loud it is or how hard i push the sub on the Gain knob it never blinks clipping Dont say its the impedance cause it is wired directly in parallel Positive and negative to negative already checked that. Any ideas????? My box it tuned around 33 hz.. My subsonic is around 25. and my LPF is around ................. Sub is DC lvl 3 15 on AQ750 at one ohm just wondering how much voltage the rcas from your head unit put out? Link to comment Share on other sites More sharing options...

HatersGonnaHate Posted August 29, 2011 Report Share Posted August 29, 2011 Quick question Ray... My friend has a 2011 Honda Accord, she wants to keep the stock head unit but she wants to have a system too. Do you by any chance know what wire to tap into to hook up the remote wire? 12volt doesn't have the diagram and Mitchell on demand doesn't have it either.

Bumpindemlowzz Posted August 29, 2011 Report Share Posted August 29, 2011 I have question. I have a crescendo 4channel 1000.4 and everytime i hit a bump sound cuts and lowers automatically. I turn the volume up on the deck and itll fix itself. I know its got to be a loose connection somewhere but all connections are good. I already replaced rca's twice to remedy but no luck. Could the actual speaker connections cause the amp to cut to lower volume? Im fearing somethings wrong with the amp, subwoofer works fine as usual btw. Could it be the brand rcas i use? they are just walmart scroshe ones 2010 Silverado 18" DC XL 18 DC 2k XS Power Batts Link to comment Share on other sites More sharing options...
