Hey there guys, I searched on the forum and I could not find a post on this. So heres the story. I have a 1993 Mazda RX7 that has a Alpine CD player. Car was never equip with the Bose bass tube so I went out and bought one. I see that there is a factory amp attached to it and oh course I do not have the factory harness for it to plug into. What I did was tapped into the red and green wires which where the wires to the sub and ran it to a Alpine amp. My question is there anyway I can run the factory Bose amp on the sub? Trying to have a clean look. Also looking to put in the stock cd and tape player but the guy that owned the car before me cut the factory harness. Let me know , Thanks in advance.

I wouldn't bother. As fancy as the acoustic wave system looks, its performance is nothing special. I would go listen to it in another a rx-7 before you do through the trouble.

don't bother. unless you are using the factory amp with the factory "subs" then it's going to sound like regular old speakers and not subwoofers.

when my rear unit's amp died, i replaced it with an alpine amp. i have it hooked up to my head unit's "sub out" channel, but no matter how i adjust the amp/headunit i can't get the rear "subs" to sound like they did with the factory amp. now they just sound like speakers - which is fine with me because i don't really care about having lots of bass.

your best bet is to just use a shallow 8" or 10" aftermarket sub with a small mono channel amp.

anyway, here are some photos from what i did to "fix" my rear unit when the amp died:

the system, opened up:


"subs" removed:


"subs" rewired for use with aftermarket amp:


hooked up to an alpine amp:


honestly, at this point, i'm looking to ditch the tubular unit. i want to get some speaker grills to replace the rear pillar bins and put some speakers there, then put a small 8" sub in the trunk.

i think this is the best route: 1 speaker in each door, 2 speakers in the rear pilars, and a small sub in the trunk.

cheers.

I agree with theorie and ihor. You may be able to hook it up but it will not really sound that great. Mine sounded ok when it was working. Then my door speakers took a dive and I ripped all that out and installed all Memphis audio. Best choice I ever made. I run a small 10" sub and it is perfect. Really if you just installed some nice 6x9's with the right door speakers sound in the car would be great and have a good range. Personally I would never install a sub smaller than a 10 just because the sound range is not where it really needs to be for a real subwoofer. You will pull off a cleaner, crisper sound with the correct addition of mids/highs in the doors and behind the driver/passenger seats.

I hooked up a 200 Watt Rockford fosgate to these speakers and used the sub output on my deck and wow it sounds like actual car subs. I had a smaller amp running the speakers and it sounded like crap. Also if you are running aftermarket amp, make sure that on the first speaker you hook the positiive wire to the positive terminal on the amp and the negative wire to the negative terminal on the amp. On the second speaker do the reverse, so hook the positive wire on the negative terminal and the negative wire on the positive terminal on the amp. Reason for this is becuase the speaker are both facing each other. You will defiinity notice the sound difference hooking it up that way
