wait till you all see the mess i am working on now, complete gut...... system was installed less than 2 weeks ago. one of the worse i ever saw, BYC you could not even have done this shitty of work.
Every single thing was done wrong, not one correct item.
under hood, NO fuse on 0 guage to rear batteries, they only had 4 guage connectors so they cut down the wire to fit, smashed and taped, every one pulled out.
thru fire wall looked like a beaver chewed a hole, no gromet nothing,
wiring in dash giant birds nest. front doors, used factory wires connected to crossover that hung so everytime you opened and closed the doors they banged.
rear doors have 2 5 1/4 in them, each suppose to have own crossover, they used one for both. rear deck 6 x9 crossovers hanging,
Now the fun stuff, BOX, build out side car, could not fit in (4 12's) so they cut the car's trunk opening, pealed back metal, pushed box in and rewelded (never in 20 years have i seen this), in box construction they could not cut the speaker opening to get subs to fit, so there was 1/4 to 1/2 of liquid nails under around in on everywhere on the subs, use of wood glue must be a mystery to them, and also predrilling screw holes, as i could pull each panel apart with out tools, open it up and find 2 batteries in the box!
amps we mounted to top of box between subs, the 2 mono amps, only one was hooked up to play, but look like it should, the 2 4 channel amps only 1/2 of each amp used, no it was not bridged, just not hooked up... there are 26 mids/highs in this car. the also wired one amp as the right side and the other the left? there many more mistakes problems, breakage. So i completly took every thing out, rewire front to back, box is being buit in the car, for the 4 12's in 8 cubes tuned to 35hz, with 2 6" aero ports thru rear deck (they just came in they are huge) subs firing back, ported up, batteries were mounted in spare tire well, the 2 4 channels amps & electrontic crossover going on box behind fold down back seats, and the 2 3K mono amps on a floating amp rack in trunk.
i'll take pictures now as it is going back together, i have no idea how loud this will be.
