In my 1988 Civic DX Hatchback I have a Pioneer DEH-P3900MP head unit, Pioneer 6 1/2" 3-ways in the front doors, Pioneer 6 1/2" 4-ways in the rear deck, also two Infinity Kappa Perfect 10.1 10" subs in the hatch power by a Profile AP1200. Also due to the 3 and 4 ways not handling bass AT ALL I have installed 4 bass blockers in the positive speaker wire so I can now max out my head units volume with NO DISTORTION.

For those of you who may have also experienced the annoying rattle that is given off from the rear of an 88-91 hatch, even when idling at a stop light. There is a QUICK and SIMPLE fix to it. I was standing and looking into by hatch area, trying to find the source but then realized it wat the hook that held the hatch down, so i simply wrapped it in duct tape and VOILA!!! no more rattling!!! I also had a loose speaker baffle in the rear which i simply braced with some furniture felt pads i'd left in my car after a trip to lowes. (I'm really cheap, WHO NEEDS DYNOMAT!!!!????)

BTW I did all of this myself (Even the amp wiring) with out a clue what I was doing. I just like having such an old car because it is SO simple to work on.

 

.... cool ....
