I have a 92 lebaron convertible with a factory Infinity am/fm/cd player...I just replaced the front 5 1/4 speakers with some new Pio9neers. I just find the volume is too low..I LOVE the look of the factory one in the dash but would like to boost the sound a bit...not rattle windows just a little louder to cover wind noise with the top down. Can I do that or do I have to go aftermarket? What size amp should I use if I stayed with the 5 1/4 fron't and rear. I also need to replace the 3 inch ones on the dash..Are they still available ? These do absolutely nothing!
