Equipment used before modification: host pioneer DEH-P1; power amplifier: McGuire 4*100W; front speaker: Pioneer C-130R; rear speaker: Alpine 694A.
The purpose of the modification: requires purely vocal, violin, piano, serenade and other works, must have clear and soft high-pitched, sweet mid-range, strong and clear but not very large bass... I have been playing family fever audio for many years. Experience, with LS3/5A as the reference sound quality, at least after the modification to reach the former 8-9 level... This is the front door to the 6-inch speaker speaker seat, made with MDF and polished smooth, use a day, not to mention time Long, poorly polished will affect the appearance of the finished work.

This is the rear Alpine 649A speaker, because I do not pursue strong bass, no intention to install a subwoofer, so this modification did not change the position, just the original double-note input, only to connect the bass, as a supplement to the front door speaker . . . . .
This is the front door that is reinforced and soundproofed, all using German Wooler soundproofing material, the newly opened speaker position on the lower left, the original horn position and other hollows are closed with fiberboard (the upper skein is fixed for easy maintenance), then The surface is covered with soundproof material.
This is the completion picture of the Pioneer C-130R set horn that I used to use in the front door. In fact, the sound quality of this pair of speakers is good, but I asked for it too special, so I have to condescend it... The price is about 1200 yuan. .
The rear 694A speaker is also the most controversial practice. The usual modification shop will say that the bass is not enough, but in my own case, the bass needs quality, not the weight. The price is 890 (wholesale) around 1200 (retail).
This is the photo after the front door is completed, the speaker is KEF KER 160B, the supporting treble is KEF KER 23 high-pitched king, KEF is the British fever factory, but the car audio products of the factory have been discontinued two years ago, I have finally found Chad, the sound effect is warm and sweet, the price is 4XXX yuan.
This is the most expensive part of the conversion process - the rear tail box. The two transparent boxes on the upper left are the crossovers of the front KEF speakers, the lower left is the British GENESIS amplifier, model AUL MONO 2*100W, the brand is super fever Brand, the price is 500 pounds in the UK, plus tariffs and dealer profits, how much do you count yourself, the middle is the large capacitor, the right is the British MACROM 4 * 100W amplifier, the price is more than 3,500 yuan, push the latter two pairs of speakers.
