Hello guys, i need some input on a potential setup... I'm considering purchasing an Xtant x604 amp to drive a pair of Pioneer TS-C720PRS. . . I like the idea of a nice front stage, so I'm gonna stick with just those components for now to see how it sounds. T

hat amp kicks out 4 x 75 watts per channel @ 4 ohms, 2 x 300 bridged @ 4 as well. . . Would 75 watts to those speakers sound good? Would 300 be overkill? I wanna keep my options open just in case I decided to add rear speakers.

Xtant amps are legendary and are good clean amps, I had a x603 myself. 75 watts is fine as well as 300 watts if you use caution and cross them over high enough so that they don't break up at the low end.

Incase this is of interest, my 604 blew up a midrange speaker and it took them about 6 months to get the amp repaired. I bought it new and I don't use my car stereo very much and don't crank it up. I can't say what went wrong, all I know is it was professionally installed, although I think I might have a grounding problem in my car somewhere because there's some intermittent buzzing from one of my midbass speakers that increases when I rev my engine. Hopefully it was a one time thing and most likely all brands have one of their products fail on occassion. However I'm suprised it took so long to get it fixed.

It cost me almost $500 Cnd to get a new 4" scan speak shipped to me from madisound. The installer said xtant won't pay for blown speakers caused by their amp unless it's their own brand of speakers. I should email xtant to ask them what happens if the amp blows another speaker,... wait another 6 months for the amp to get fixed and buy another speaker? Well the amp did last a couple of years although I didn't actually use it much, so am hoping it will last a few more years. Next time I hear any strange sound I'll shut the power off right away. The last time I didn't shut it down right away since the noise wasn't very loud, but then as it started to get louder I pushed the button on the headunit but it takes about a second for the power to shut off while holding the button and during that time I saw smoke start to come out around the speaker...so if it happens again I hope I'm fast enough to save the speaker.

as far as i know you could blow them there about 50 rms and 150 peak for the ts-c720prs speakers which when i read it come out to be 25 rms per speaker. if you bought two sets 4 speakers and ran them in a series parallel configure. you mite be able to run them with the gain set so the output is lower. that would be off one of the four channels. you could just run them off the head unit/cd player and attach and buy the four channel for a set of 300 rms subs is how i see it. i did not look up the x604 just did not need to most amps made are meant for small subs. very hard to find the old amps that are like head units amps small and efficient with little power like 37.7x4 etc...

There are people running 200+ wpc to them. Like the other poster said, cross them fairly high(100 Hz would be pretty good IMO).

That said, I love Xtants. Just remember to set your gains right. Search "how to set your gains" and remember, amps do not kill speakers, people kill speakers.

I don't post much, but I owned and X603. Be aware that Xtants use x-over chips, the on-board x-over is not continously variable. You'll need access to the chips in order to change any x-over points if you plan on using the onboard x-over. In all a very solid amp and the additional passive rear outputs were pretty cool in it's day.

I've had Xtant amps since they started way back in 97 or so. I still use three in my current install. I haven't had problems except one that had a whiny power supply which they promptly repaired under warranty. If I could change one thing would be the size of them. They are huge!! As a retailer I had very few that needed repairs and they were always quick with returning them.

Xtant's amps are great, under-rated for their power, but their size is huge. I'm running a X603 now, actually have 2 of them and a X604.

I don't mind the chips for freq. selection, makes them much more customizable for any setup.

I called Xtant to get some chips before I sold my 603, and they had very few. So, grab them while you still can.

I still like a variable crossover better, I think folks tend to get caught up in numbers and not the sound.
