450/4 vs pdx4.150

[BMW Sidewayz 10+ year member]

I'm currently re-configuring the set-up that I've not yet hooked up. My original plan was to run the 165K2p and 165v to be powered by a JL 450/4, but I just purchased the Phoenix Gold Ti6 elite components 150x2 RMS so now I have to sell my 450/4 and get an amp thats 150x4. I'm currently looking into the Alpine PDX4.150. I don't know it seems really small and its a class D. My other option was to get 2 JL 300/2, but thats alot of extra weight and room. So it would be nice to know if anyone has any suggestions, I would really appreciate it.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

What I have so far:

JL 1000/1 1000x1

JL 450/4 100x2 + 75x2

JL 300/4 (broken)

Focal 165K2P U/G 100x2

Focal 165v 75x2

PG Ti6 elite comp 150x2

And yet to come...

Subs:

Don't know yet, most likely a W7 or 2 2007 S10L7s in max rec enclosure for Loooows.

head unit:

Kenwood Ddx-8017

i'd either get the 2 300/4s if you wanna showcase them or the 4.150 if you wanna hide it.

Isn't there a difference in power? how can that small amp do as much as 2 300/2? And besides a class A/B is believed to sound better than a class D in most cases. and the technology behind the slash amps like, power output from 11v-14v, high damping factor, THD, etc, etc. Its Alpine's debut on the PDX amps that have no reputation as a product. I really dont want to have to use 3 amps in my car. I would like to keep it minimal.

You don't have to put rated power to speakers.

I would use the 450/4 and decide from there.

Just because they are rated at 150w RMS doesn't mean they require it....especially if you are using one pair for rear fill.

Isn't there a difference in power?

Yes, probably in favor of the PDX.

CA&E Tested it to do just shy of 500w x 2 bridged.

Size has nothing to do with power.

And besides a class A/B is believed to sound better than a class D in most cases.

Myth.

Its Alpine's debut on the PDX amps that have no reputation as a product.

I wouldn't exactly call it a leap of faith to go with the Alpine.

They've been out for over a year now.....plenty of people have used them, plenty of people have liked them.

I would like to keep it minimal.

Sounds like the PDX is the amplifier for you then......if you feel the need to change.

pdx 4.150 even 4.100 (benched at 135wrms x 4 usually) will be enough to make everyone happy

How much you guys think I can get for the 450/4?

 

[Jdm94Coupe 10+ year member]

i guess u didnt read my post..... u ever thought about a 650.4 or a 850.4 kicker??

 

[BMW Sidewayz 10+ year member]

I've never experienced kicker amps, but also considering them. I know that the kx2500 is very popular among members here.

 

[Jdm94Coupe 10+ year member]

yepp and the zx650.4 and zx850.4 are better then both amps u are considering, lol.......... in my personal opinion

i also have a rare TOTAL T.M.A. 440/4 amp and its a ****ing BEAST!!!

I wouldn't consider them "better"......

"Best" is just what makes you happy. Happiness is just an option though //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif
