I am a Basshead from the Mid 80s,.. Ive had so many systems and installed ,worked in shops on weekends and all kinds of stuff as one of the Hobby portions, and held a 40-80hr weekly job for years with a pension coming soon. Ive had some really large build outs and loud ones even.Expensive, Dirt Cheap and just a plain HU and 5.25 coax at times. LOL. i will do my last Large buildout to try for the 150DB crowd and at least to say I have made it on paper . Then Ill go back to more of a SQ/SQL type sound system. I have the gear.. its been TIME that Ive always needed. Im finally about to have that time and utilize my tools and see if I still have any patience left/Learn some more. LOL. I want to do my 20014 2500HD 4 dr. with a nice sound system in it.Just need the time. Have everything with exception of a DD HU, though I could use an older SDin HU I have on hand. All my vehicles are older.. but paid off and in mechaniacly excellent shape as i take care of them in that respect.
