Racebum,
Who out there makes a good class A/B amp out there besides JL or Audison in your opinion? Just wondering if there are some other good options. To me it looks like for the clams the 300 and 600 slash would be the combo to have without costing a veritable fortune.

zapco c2k and the new Z series along with the older studio are good. the new z series looks really promising.

president of dynaudio was using older ppi power class for awhile in a test car. these are large though.

i can get you the slash 600/1v3 for 425 and the 300/4v3 for 375 new with warranty via my guy. google stereo king clackamas oregon. ask for kevin churchill. say you're a friend of kyle's and mention the deal he gave me which is this. you would be paying shipping from oregon but it's a pretty solid price. haven't seen anything close online, especially not from a legitimate store. you could buy just one or both. that would make the 300/4 basically $400 shipped.

I have not seen prices that you are describing anywhere. That makes it pretty damn tempting!!

Yeah, those do look like some nice amps but looking at the dimensions they are pretty darn big. My old Rockford Power series amps are great big bruisers that seen to have endless supplies of power but it sounds like I can improve the SQ quite a bit with the right amps. I solved my head unit problem and will probably tackle the amps next, then speaks but it does sound good enough that I can at tolerate it for now, esp with the Alpine head unit.

They are not that big. I have the v2 models (silver) in my 2005 C6 and they didn't take much room. Just had a nice little amp rack on the shelf right behind the seats.
Something like this.
****This is not my car but my amp rack look just like this. I have the 300/4 and the 500/1 but for some strange reason I can't find any pics of my old audio setup.
I am pretty sure the v3 models (black) are the same dimensions. I could be wrong.

300/4 and 600/1 are about the same size as the 300/2 on the left. that 450/4 is BIG
i also agree. for the money there is nothing better. you have to go larger and more expensive with the zapco z series to get competitive and a bit more refined on the highs. even still i would have to critically listen. some of the recent zapco amps i have heard don't sound like their older magical ones

Hey Kyle,
What do you think of this amp for a combination class a/b and d 5 channel?
http://www.audison.eu/index.php?page=product&id=71
Looks like around a grand to buy it...

if you google that amp. pictures of the guts show up in images. all quality components inside and a great layout

Check out this tech sheet: file:///C:/Users/jtheis/Downloads/av5.1k_hd_tech_sheet_tech_sheet.pdf
It looks like 75w x 2 of class A, 140w x 2 of Class A/B, and 600w x 1 of class D, and that it would be better suited for up front two way active? I would be tempted to use the 140 x 2 for up front and 75 x 2 for the rear but then you are putting the class A sound in the rear? How much difference between Class A and Class A/B?

Dont know why i was looking but figured boston acoustic would be cleaned out of their G.T. amp's...
WOW they had a GT-2200 2 Channel.. I couldnt resist and ordered it up.
For 200 watts per channel @4 ohm's and under 200.00. Just couldnt resist..

Got the boston GT-2200 in already.... Hard to believe it is 200 watt to each channel after dialing it in.... Seems and feels less...
Makes me wonder what other's had said in old post's years ago..... Are the gut's the same in the indonesia one's ,, compared to the old one's made in Italy, like the gt-42, gt-28,gt-50

run that amp active through a bit one and pick up a clean 2x50 something or another for the rear fill. an old zapco z100 would be clean and under $200 used. they are also small
the morel hybrid and better elate would be thrilled with that amount of power. same with the dynaudio esotar system. by warned if you go dynaudio they #1 are a bit more than elates and #2 the tweeters are large

I only listened to a few song's on my fav c.d. , so maybe its just a diff sound from the older boston GT-42 (made in Italy)
Gotta give it more play time... BUT, BOY is it crystal clear.!!!!

this is one main reason i used the JL slash. they have the old sound and i like that.
if the amps produce the voltage they are making the watts. how dynamic that is; is another story. an old amp with a lot of headroom would set to 27v then on strong notes you may see 60v if you measure during music. that's a lot more uncommon now a days unless the $$ goes up

likely a different sound. the older a/b amps had this warmer more lively sound. some of the new gear. as you say is very clear but it doesn't quite have the same pair of hanging *****

Then i got itch to send out my BOSTON GT-42 to have the right channel whine fixed...which is pretty bad.. But then i never tried a ground loop isol...But i Rather not... because on old audio forum post's i see there were a few issues with the Early GT amp's made in Italy making noise but not all of them did. So it may be a fix....
I work at local chrysler dealer and the local UNITED RADIO that does all the automotive brand misc fixes like radio's/module's/amp's/instument cluster's/ect could look at and quote me..And when i ordered the gt2200 that is where it was shipped from..and they have more..
So long story short, i rather have that GT-42 in the veh...And use that bridged on ch 3-4 for sub until i get my dedicated amp for the sub.
OH,,, If anyone reading is interested in knowing. But Boston has the GT-2200 in their refurb section aval to buy.. Good amp for 200.00 and 200 watt each channel. and clean... I could package mine back up and sell as new by just removing the B stock sticker.

old boston stuff was pretty good. another magic amp from the 90s were the phoenix gold ZPA .3 and .5. brutally overbuilt and amazing headroom. if you ever see a deal on these they will make you grin
