i used 2 channel for tweeters and 2 channel for mid bass.. means tat i cant use this amp to push my woofer anymore? i havent buy my woofer yet la.

i need buy a 2chan/mono for my woofer now?

The answer is yes! you need another amp for you woofer...unless u want to use passive crossover for ur mid+tweeters with 2 channels and another 2 for woofer..

I prefer ur current setup and get another amp ..can tune better with e-crossover.

nice amp u got there..the original V12.

what HU or xo you using?

my HU is pioneer DEH-P6850MP, and i guess the HU can support passive setup only..

my setup now is plan to do a 2 channel for front comp set and bridge the other 2 channel for my woofer lor.. something like a 2.1 setup..

Gimme ur comments.. thanks..

bridge u only get 130w rms

what kind of woofer you want to use?

What type of car are you hooking it up to? sedan or hatchback? type of music? SQ, R&B or techno? If have budget go for 1 more additonal amp & run a full 2 or 3-way setup.

RF punch p1 woofers lo.. 150W/300W Max.

@MobyDick. Sedan, my Wira lo. SQ only. im playing passive, still can 2 way or 3 way setup?

2 way passive or 3 way passive also can wat.... but not active...

can explain 2 way and 3 way passive meaning ka..? ahha..

go google it la.....

mean u use the passive crossover come together with ur component set

im using the passive crossover tat comes with my comp set now lo..

im using the same amp never let me down hehe

depends on ur component set then. compare its rms / nominal power is under 55W, then u can juz use two channels for the set n the bridge the other to for ur sub. like that of course u're not using ur sub at its potential, but you do save some money

if ur comp needs >= 55W, then i suggest u get a monoblock la since its a pity if ure not using ur component's potential

stratos, mind to share the price of ur V12 amp and HU? since we are from miri.. just want to know current market price

btw, where did u buy the pioneer HU?

well im from miri hehe... i got the v12 amp for rm900 at union audio near emart there... other places around 1k

where to get rockford fosgate punch P1 and P2 woofer?

u know the price?

i bought it at RM750 only.. its used for a month plus only.. lucky me lor.. the previous owner bought it at Singapore after conversion is rm 1300. My pioneer HU i bought it here in LYN.

@dvlzplayground.. wow so many people from miri here.. ahhaa.. its a pretty good amp.. i always support alpine V12 and V-power amp.. the new PDX amp sound is superb but lack of bass. i tried it oredy ar Megashine tat day.

@athlonxp.. so far Miri only selling P1 12" woofer.. RM 600 for the woofer only and RM1k for the woofer and ori enclosure, with the cool silver air outlet design.. tats the price they gave me la.. confirm ori and not AP warranty. for AP warranty is RM 450 like tat i think.. not recommended tho..

may i know is your alpine v12 and the new PDX uses which class amplifier? Class A/B or Class D?

For Wira sedan you can maintain your current setup for your existing 2-Way front passive component setup with some slight tweeking of your build-in active at your amps. Go for a single 12" woofer with full enclosure bridge matching your current amps output; tuned well & you should attain your desired SQ level in relation to your hardware. You can hook-up the rear speaker directly to the HU to provide some sort of staging for the rear passengers but keep the levels low so as not to 'cross' for the front listening pleasure.

Class A/B for my V12.. the PDX i not sure.. Its class A/B also.. coz i remember see-ing the other PDX series is Class D mono.

this is how i was planning to do as well.. 2.1 setup lo.. the shop i went too recommend me a full closed enclosure for my woofer box as well..

Go for a ported enclosure which I'd think will complement your current amp.

why not sealed enclosure le?

quite expensive..almost same price as alpine type s

or can get a pegasus PG1225 already and got some change left..

have u ever listen to that RF P1? how is the sound?

sealed box require extra rms to get it sound decent..like your woofer is 150rms, your amp must be more than that like 200rms to push it

of course this is just rough estimation, it is up to u

i listen to Punch P1, P2 and P3 b4.. P1 is very nice.. enough for entry level SQ.. P2 more to SPL and P3 also SPL oredy..

and the RMS not necessary need to be over the woofer RMS.. i ever see my fren go competition the amp after bridges is just around 160RMS can push a 200RMS woofer nicely..

icic..

too bad never see people sell RF punch P1 in kuching

ice ppl said if amp rms bigger than woofer will sound nicer wor..but i duno la..i ever try to use a 400rms woofer with 280w amp..it sound like shit and weak

coz tat really under power already i think.. i not sure also.. dun too low the the RMS differences.. i think mainly is more to the settings as well la..

The Punch P1 got 2 models ler.. 1 is the old type 1 o.. and another is the new 1 i think.. different design..

In-Car listening pleasure, In-Car techno, Jam-Zone Outer Car Techno or Competition SPL requires completely different setup procedures for amplifier Ohm-Bridging & Woofer-Flex to maximise application weather for listening or competition.

like me if listening the amp setting will record down de.. coz when unplug the battery for more then few minutes the amp setting will be reseted..
