Is anyone a dealer for Xtant anymore? I can't find anywhere online as a source for purchasing these amps. Do they just deal with the local mom and pop dealer/installers?

very nice write up, but if you're using an external amp for your sub, couldn't you just adjust the filter in your amp to filter out mid to high frequencies and raise the gain causing more bass and allowing you to turn the bass down for the rest of your speakers?
I just bought some high pass filters for my headrest speakers (tsunami's that filter out everything below 100hz). I went to install them today and when I took my deck out I noticed that my sub out is hooked to the rear speaker out. I switched it over and now I can keep my rear speakers in full range and turn the built in hpf up to 50hz and everything sounds crystal clear. Now I don't need the hpf's that I bought lol.
Also, running 4ohm speakers in your headrest on an aftermarket deck is safe. Most new decks can handle 2ohms -8ohms safely per channel. It's 1 ohm and more than 8 that you have to worry about.
My setup is Pioneer DEH-P5800MP head unit, 2- Nitro 3-way 4x10 speakers in the dash (100/300 watts rms/max each), 2- AG Audio 3-1/2" 2-way speakers in each headrest (35/100 watts rms/max each), Scosche 250/550 watt two way amp bridged to a 250/750 watt 10" LA sub behind the passenger seat. Sounds amazing and I spent about $450. $200 for the deck, $75 for the amp, $35 for the sub, $115 for all of the speakers.
Again, very nice write up.

The Xtant 1.1i amp is designed as a Class D full range amp. It doesn't have a built-in filter/crossover which is why I've used an external filter. I've adjusted the gain so the bass is balanced with the rest of the system. The best thing about this amp is that's it's powerful for it's size and will fit on the floor under the passenger seat without any interference.

yeah, I wasn't too worried about it all looking stock anymore, so I was able to buy a more inexpensive amp. I don't have audiophile sound quality (almost impossible using stock speaker locations in the fiero), but it sounds great. I'm really satisfied with how well the cheap speakers I bought sound. They're made of high quality material, so I shouldn't have problems with them, and they sound better than some fosgates that I had in my chrysler conquest.
Did you make any sort of enclosure for the dash speakers? I've been told that every speaker should be enclosed to create great sound, I just haven't tried to tackle it yet with the dash.

I just installed the Tang Band subwoofer in the factory housing (modified and filled per your directions). I'm using the factory subwoofer amp with an aftermarket head unit. It sounds AWESOME.

I'm glad you're more than happy with how great this sub works.
People who hear this system can't believe I'm running all the main speakers off a factory deck, and that such a small sunwoofer makes such BIG bass. Now it's NOT going to sound like your typical boom-box ricer driving down the street, but it is MORE than adequate to fill out any sound system in the Fiero.
Did you do something to increase the impedance of the components? The info I saw said they were 2 ohm... isn't that a little rough on the head unit?
No. It seems to be OK - no problems with these. You have to remember it's running through a crossover and that impedance varies somewhat throughout the frequency range. Infinity also says that these are "safe" for factory decks, none of which would be 2ohms anyway.
While I would not personally wire 4ohm headrest speakers in parallel, which creates a 2ohm load, others have done so without problems.
Great write up! With this set up, can you still use the stock premium sound slider switch on the headliner?
Thanks. I have an 84 so it didn't have a slider (premium sound wasn't available until 86?). But someone figured out a way to make the slider work with an aftermarket amp. It's covered here: https://www.fiero.nl/forum/Forum2/HTML/097104.html
