kickass audio Posted January 9, 2013 Report Share Posted January 9, 2013 it depends on what size bolt you can fit through your mounting holes on your woofers basket. I drilled out my basket a little more to fit 1/4 bolts and i had to get them longer than 3 inches as my subs gasket was about 3/4" thick and the baffle was 1.5" thick so remember the length as well for how much space your subs gasket takes up as well as the depth of your baffle that you mount the sub onto. A 3/8 should be alright for you though. 2004 GMC Envoy1 XS power S3400 batt under the hood and 4 XS Power D3100's battery installed in the rear by the amps0 gauge power wire from front to backAlpine iva-w205 touchscreen dvd/cd/mp3/ipod/am/fm/gps headunitSundown Audio SAX-200.4 amp for my mids and highs8 gauge speaker wire from amp to woofer270 amp Mechman AltRockford Fosgate T1652-s component speakersRockford Fosgate 3Sixty.2 sound processorRca's from Rockford Fosgate and Monster Cable14 gauge speaker wire for the mids and highs1 18" Ascendant Audio SMD Dual 1 ohm with custom Black & Blue carbon fiber and hand signed dustcapBox: 5.66 cubic feet net volume box tuned to 30.13Hz with 1.5" wide wooden dowels and 1.5" thick baffle1 DC Audio 5.0k amp wired to .5 ohms nominal with an imp rise of 1.35 ohms for the single AA SMD 18"Future Vision 8000k 50w bi-xenon projector HID's with 4300k 35w fog lightsLink to my build: Buildupdates/progress Link to comment Share on other sites More sharing options...

kickass audio Posted January 10, 2013 Report Share Posted January 10, 2013 lol sorry i am totally not thinking right. i did use 1/4x3" bolts for my SMD though. I didnt have to drill the basket out too much to make them fit so it wasnt a big deal. I was originally thinking to tap the basket with my tap and die kit i have so that the basket was threaded but when my dad saw me doing that he reminded my dumbass that the threads were more than likely not going to line up and cross thread to try and put the bolt through the thread pattern on my basket and the thread pattern on the t-nuts. 2004 GMC Envoy1 XS power S3400 batt under the hood and 4 XS Power D3100's battery installed in the rear by the amps0 gauge power wire from front to backAlpine iva-w205 touchscreen dvd/cd/mp3/ipod/am/fm/gps headunitSundown Audio SAX-200.4 amp for my mids and highs8 gauge speaker wire from amp to woofer270 amp Mechman AltRockford Fosgate T1652-s component speakersRockford Fosgate 3Sixty.2 sound processorRca's from Rockford Fosgate and Monster Cable14 gauge speaker wire for the mids and highs1 18" Ascendant Audio SMD Dual 1 ohm with custom Black & Blue carbon fiber and hand signed dustcapBox: 5.66 cubic feet net volume box tuned to 30.13Hz with 1.5" wide wooden dowels and 1.5" thick baffle1 DC Audio 5.0k amp wired to .5 ohms nominal with an imp rise of 1.35 ohms for the single AA SMD 18"Future Vision 8000k 50w bi-xenon projector HID's with 4300k 35w fog lightsLink to my build: Buildupdates/progress Link to comment Share on other sites More sharing options...
