Ok, im probobly going into the military so i want to plan a full build for when i get back and get my bonus. the car will be a 2003 New Beetle Turbo S. i already know what speakers i will be using for highs and mids(Herz 3 way componant up front and herz 2 way componant in rear), the amp to run that i have no clue.
as for subs im going to go overkill and go with an 8 inch sealed, a 10 inch sealed, and then a 13.5 ported. as for sub choice i was thinking JL 8W1, 10W3 and either 13W7 or 13W6. im leaning towards the W6 as im more of a SQ person and the W6 sounds better to me. the subs will all be in a "seperate" enclosure but the enclosures wil be fiberglassed together into one enclosure to fit my trunk.
now on to amp choice. i have no clue what amp/amps to choose to get it all to work. id like to be able to set seperate crossovers and subsonic for each of the subs(not sure if there is a standalone crossover that can set subsonic, fill me in). i dont want to have to get a seperate amp for each sub as there will not be enough space in my trunk.
Im going to do an upgraded alternator, have all the wiring and such done by a local shop, and i am getting a capacitor, most likley a very large capacitor. HU is still under considearation as well so if you have any ideas throw them in as well.
also on a side note, if you have any subs that compare or surpass the JL subs for the same price or cheaper throw them in. however i do love JL and have always hade good luck with JL, even running the subs at more than double the RMS rating.
