mis-communication error. i have an OEM head unit, but obviously not an amplifier... are the head units in cars with the amplified system the same?

Gain control on the camera muted it as the bass came on, but trust me, it came on strong enough to shake my rear view mirror, just like the Zilla:



Everything is in EXCEPT the rear speaker grilles with tweeters. I have to cut my rear deck to fit the tweeties. A simple job for a dremel or strong scissors without removing the rear deck.

This was tonight'* work:

It doesn't matter. The amp samples the front and rear speaker inputs (splice in) has power, radio on signal, and ground, all spliced from the OEM radio harness, and then your standard rear speaker wires power the standard SSEi rear speakers AND tweeters, then you run 4 new wires for the amp output to the factory SSEi subs.

Read my post at the top of this page. It answers your question.

All 8 wires for the factory speakers get spliced to the amp. I did this in the radio harness directly behind the radio. Very easy access.

While wire colors changed a bit from year to year in my case (93 amp in a 95), it doesn't really matter. Wire locations (pin numbers) remained the same.

The most difficult part of the job (no kidding) was running the new wires to the trunk.

Tonight I'll hack up my rear deck for the larger speaker grilles and tweeters, then wire the tweets in. That'* the only 'audible' thing left to do. Cosmetic as well. It'll be completely done by that point.

Done. Finished cutting in the rear deck for the bigger speaker grilles and tweeters. Found that the shape of the 'humps' is a little different, but not by much. Worked out pretty well.

I drove it yesterday without the tweeters, and I have to tell you it makes a HUGE difference with them last night after they were installed. Both cars now sound identical. Components are completely interchangeable between them as well, as I used factory wiring from the ground up.

That'* really nicely done. When I got my 94, the sound was already pretty pooped out by the previous owner. I had no tweeters in the back. :( I love your attention to detail by painting the speaker covers and making it all OE-like. Do your speakers provide in-tune bass, or do they just give you a WHOMF that'* the same each time hard bass hits no matter the pitch? Hard bass specifically.
