92' Sc400 Nakamichi New Woofer

Recommended Posts

Hi, my name's Cody and I know this is my first post here, but I'm really having trouble with the nakamichi stereo and I hope someone can help.

I'm looking for more bass in my 1992 Nakamichi SC400 and here's the thing. A few years ago I knew nothing about stereos (and probably still don't today), I had my cousin come and switch out all the speakers/tweeters and subwoofer in the car, thinking it would sound much better. We kept the stock HU and amplifier because I want a stock look and I like the equalizer controls in the stock HU.

Now, I'm thinking to add an aftermarket amplifier to drive the subwoofer to increase the bass, will I be able to just drive the new amplifier using the output signals from the stock amplifier? Or is there another method? I haven't encountered such a complicated system before. I've changed stereos and added amps before, but they were on more straightforward cars like ford contour, acura rsx, honda accord.

Thanks for your help!!

I have a 2006 GS300 with the Mark Levenson stereo. I also wanted more bass so I put a sub-woofer box in the trunk with 2 JL-Audio 10" subs and a Polk Audio Class D subwoofer amp. I had a car stereo shop hook it up. It needed a thick power wire to the battery and a HI-Low adapter. The Hi-Low adapter clips on to the existing sub woofer wires and sends the audio to the new amp (and auto turn-on).

The bass is awesome and the stereo sounds much better. If you do the same, get a good quality Hi-Low adapter as they vary. I really like my Polk amp. I had a JL-Audio amp with more power, but it ran very hot and would shut down after 45 minutes of hard use and eventually went bad all together. The class D Polk amp from Frys sounds better (to me), cranks, and barley gets warm at all.

good luck.

Thanks!! But I dont need a separate subwoofer from the one in the stock location (already aftermarket). I only want 1 subwoofer which is currently running off the stock amplifier to run off an aftermarket amplifier instead. My problem is where to connect the input of the new amplifer from? Can I input the new amp from the output of the stock amp? That sounds weird.. Thanks for your help.
