I had a alpine v12 t757 years ago. it was a great amp. I was running a single 10" infinity kappa perfect. I am getting another 10" kappa perfect along with a new alpine mrp m650 amp, 400 RMS into 4 ohms. I was wondering about THD. Some sites including alpine's claim .08% THD, white others claim 1% THD. What's with the difference? I was very pleased with the 757 and am looking for that same quality of sound. I know some of you will say 1 10" is a waste, but I'm not into EXTREME bass as some of you may be, the one 10" will be perfect for me. Can anyone give me a heads up on the THD issue?

Thanks, Matt

 

That 650 is no where near what that 757 was. If the Alpine site has 0.08% that what I'd go with. I'll check the manual tomorrow, if I remember. I would NEVER say one 10' is a wast, if done right.

 

Thanks NEEDAZ. I am getting the Kappa perfect, havent got the amp yet. Is that Alpine m650 a good compliment for that speaker? I am not a car audio god, but am all about sound quality. any amp recomendations apprecialed. I was looking around and it seems the Kicker ZX750.1 is a decent product as well. any advise, otherwise i'm gonna go with the m650.

Thanks, Matt

 

kicker makes veery good strong amps.. im not suure how good the alpines compare.. but i know the kickers will put out a bit more than there rated

 

i got a nice Hifonics BXI1206D some people say there good some people say there **** , mines perfect pushing my type 4's great wired to 1 ohm load

 

new hifonics are 70% effcient i beleive..i was going to go with hifonics.. but found my memphis for only 150 on ebay .. rated at 1000 @ 1ohm.. maybe its pushin a little more :P

 

IMHO pick up an old school Phoenix Gold like the MS275, M44 or something around that era, probably the best amps ever made, I have an M44 pushing 2 6x9 alpines, 2 3.5 alpines in the front and two 10" subs and even with it turned all the way down it hits like a mack truck.
