my bad... both sets should play the same range.

confirmed

two pairs of comps can be hard to tune.

my approach would be to keep in mind how the human ear localizes sound. ITD, IID and HRTF are terms you sound reference. allow the speakers to play within...

haha, wellll.... it's a bit more expensive to maintain.
the new DSG gearoxes re fantastic. havent had the opportunity to actually drive one but the review with ace driver/drift king keiichi tsuchiya...

lol.. yes, bigtime star wars fan. but loosing faith in the jedi. i dont trust yoda.

the sti is a great car, dont get me wrong. the few i've driven (GC8, GDA) have poor interiors but perform well....

the built of these amps look cheap.
i need to see a proper whitepaper from polk.
i need to see some reviews if i cannot review one myself.

i've been always impressed by polk's other products.

1. keep civic. save $$. USA is in for a tough 2 yrs
2. evo - more of a driver's car. more comfy inside.
3. sti - nice agressive nature. poor handling. cheap interior
4. vw - nice inside. great...

drool... bit ten.. ummm...

i have the 9887 with imprint... i would prefer the bit ten or the three sixty v2. why?
imprint locks you into that specific model. yes, there is the PXA.. but both the...

if you are running the SIGNAL wires from one amp to another, you can do that for as many amps as you have.

you cannot daisy/join anything on the output side of things tho. but there are other...

all the guys here are correct.

dont discount the use of the door. closer to the mid range.
dont rule out using the kick panels for both either. the deepest stage i ever had was when i placed them...

i would push the envelope and go with an iPad

wears out?
if you meant "less power over time" i would say no.

you may get problems being introduced over time. as the OP said, a good amp would last years on end once installed and treated...

i tried my usual default settings:

midsbass: bandpass xover. highpass 63hz with 18db slope, lowpass 3.2khz with 12db slope.
tweets: highpass 3.2khz with 24db slope
sub: lowpass 63hz 12db slope...

unfortunately... and a big embarrassed smiley goes here ... i did this:

re-tuned the imprint for two seat. then it wasnt as loud
so i stupidly screwed with the gains and made it worse.
i then...

hi, my sr's are 2 yrs old or more. i did a rest on my system (alpine 9887 with imprint, alpine PDX400 amps, active. tweet on one pr of channels, mids on the other, 2nd amp runs subwoofer)

the mids...

there are many guides for proper gain setting on the net.
you can do it by ear and with a test cd. simplest.. and it works.

break out the scope n stuff if you're OCD :-)

you cannot tune the "imprint" manually. the use of imprint sets BOTH eq and time alignment for approx 500 points of correction.

the HU can be tuned manually, using the 5band eq and time alignment....

i use scosche efx wire. no problems. try to get the oxygen free copper. the copper-aluminum mixes arent good in any brand.

hi, the recommended power wire sizing chart is what you need to see:
http://www.the12volt.com/info/recwirsz.asp

the two main considerations are:
1- length of run
2- how much current (amps) you...

threaded aluminum spacers.

suspend the amp, facing up and allowing adequate air flow above it, using threaded aluminum spacers.

a threaded spacer is like a hollow tube but with screw threads...

3M double-side automotive tape. the grey one.

or super glue.

the FG is lighter. a 12" SR should be housed in a strong encl. built of and braced with 1" MDF. or HDF if u could find/afford/lift.

the FG encl is good for irregularly shaped location and for...

kicks

set tweet gains properly. if tweet still blows, check amp for fault

generally rear fill is a waste of ur time and $$ to setup.

but u can use it as ambient fill but only L-R attenuated would sound good. a regular L,R config would pull ur stage back... which iz bad.
