1972 Convertible Amp Makes No Change
The long story is that after starting out with a minor repair to the seatbelt retractor, I ended-up with so many "while-Im'-at-it's" that the dashboard and guage bezel ended-up coming out with the carpeting and I figured I might as well replace the speakers. After buying a set of infinity's for the front I cam across a thread on this site and decided to jump-in with an amp and shallow speakers for the kick panel. But ... after physically seeing how they'd mount in the kick panel with my 6' frame and having a stick shift, I realized there wasn't enough room. I also purchased them at the lowest cost from an internet company that doesn't take returns so I'm stuck with my coaxial & amp choice to use in the rear.
As to mounting, since I have the convertible top and I drive with the top down, I first have to put the top back in the car and then make some kind of custom enclosure so the coaxials sit between the top-down mode and the seats. First I want to get the wiring set, though.
Custom Autosound USA-6 Head Unit: 60watts/channel, 240watts/system. Has the look of an original unit with modern electronics and the I-pod jack.
Cadence TX-1502: 2 channel amp with dials set at factory and crossover mode in "Full". (I have no idea what the book is saying about what these do)
Front Speakers: Infinity 6422cfp 4x6 rated 135w peak and 45w RMS. Says nominal impedance 2.65 but box marked 4-ohms.
Rear Speakers: Polk DB651s 6.5" coaxial rated 165w peak and 55w continuous. Says nominal impedance is 4 ohms.
Wiring is: All speaker connections are soldered. Used a kit with 8-guage power & ground with ground going to the large sheet metal behind the seats forming the divider to the back storage area. Remote amp turn-on is 16-guage from head unit. Both amp and head unit are wired directly to the horn relay terminal with an in-line 60A AGH fuse. I didn't choose the fuse, it came with a wiring kit and I think it should be lower.
