I kno theres tons of new install threads, ive probably read through all of em and finally understand what i need.

I just want opinions on my build, see if i can change things around. I want to keep budget around 2000-2500. Full dynamat.

Alpine PDX-1.600

Alpine PDX-2.150

Alpine CDA-9885

Alpine SPR-17S

Alpine SWR-1022D

Alpine SWR-1042D

Whats the difference b/w 4 ohm and 2 ohm for the sub?

Im more than willing to switch out brands, i just want the best sound.

 

hmm on crutchfield, it says those type r 6 3/4 wont fit on the '02 model...is this right?

 

contact me , I sell all of those and i'm clearing out my inventory. I'll give you a damn good price.

 

oh and the OHMs is the resistance rating , depending on what amp you go with will match up the sub the best.

 

ok, so ill need to get the 4 ohm sub cuz that pdx 1 outputs in 4ohm right

 

welll yes and no... it works at 4 ohms , but gets the most power output at 2ohms , so the 2 ohm sub is better for you since your doing only 1 sub.

 

But those are both dual voice coil subs, so to get a 2ohm load, you'd want the dual 4ohm sub, wiring the VCs in parallel. otherwise, if you wanted a 4ohm load, you'd want the dual 2ohm, wiring in series.

I've read in magazine reviews that the PDX subs do in fact produce more than stated power at 2ohms, but I question why Alpine would put in the product descriptions on the website that:

 

PDX amps will... it has the same techniolgy as the JL slash series amps with the R.I.P.S. tech... regulated internal power supply... meaning that between 1.5ohm to 4ohms it puts out the same power... PDX has a type of the same technology but 2ohm for the PDX will be better , although at 4 ohm the amp will run cooler.

 

i just had a better sound test for those type r's. they dont sound great at all. thinking bout going with MB Quartz instead now, will have to goto some shops and listen to em

 

Check out JL , yes everyone says there over priced but i've gotta pretty decent prices on those. I've got an open box w3v3 12 for 170 which is a steal.
