First , let me say thanks...This forum is bad ass.
I am new here and I have not in stalled a system in 15 years.
My young wife wanted some jam in her Suburban, so last Feb I bought some stuff online I thought might mix well and sound good..and said " Happy Valentines Day, baby"..
Last week I dug a box of goodies out of storage and throwed it in the back of her ride..I work out of town, so I called the local chop shop and told the Installer my wife was coming down and hook her up with the stuff I had..."give me the best coaxes ya got in the doors and throw those 12's in a good box"....So this year, I said "Happy Valentines, Baby"..lol...thats bad.
Well yesterday I got in from work and scoped out the install... It sucked..let me just say they had the mid/high right front input crossed , the rear left out crossed out of phase and both amps grounded to the seat frame above the rear of the amps... fuken noisy that way!..I got red in the face, my friends. If I have to pay for it, I feel it should be done right to say the least...any ways I fixed the in, out, ground...and a few other least worrysome probs can wait a day or two.
Enough bichen,Heres the deal, I bought 2 Memphis PR 12's 4ohm svc...This system sounds pretty good like it is, but I am not sure I am getting all I can..I the pre fab slot ported box is tight, sounds good for 85 bucks, but is it right? I calculated using an excel program i found here at SMD that the box net vol is 2.8 cubes
with a tune of 42.7 hz. ( prolly right for a sealed box?)
Ultimately, I want to install 4 of these ( while I can still get them) in a ported box tuned to low to mid 30's
this might help..box dems: w- 36" H- 13" D- 16" Slot Port dems: 3"W x 11.5" H x 13 3/8" L I maxed my amp sub sonic level to 35hz, gain set proper @ 4v input, HU Low Pass x over 63hz 12 db/oct..250 hz 24 db/oct on amp Low pass. I have not intentionally clipped anything since I have heard u can do system damage at freq below the tuning hz...
