maybe its the amp. its not able to go down or be stable at 2ohm bridged mono. your sub is dual 4 right?

**rain18** · March 14th, 2003 01:18 AM

since the sub rating is UP TO 600 watts RMS and your amp gives out 600 watts RMS also, then the sub is already getting evrything it can handle! get it? =)

50-600 RMS watts means it can handle a minimum of of 50 watts and a max of 600 watts RMS.

wala nang headroom sa 600 RMS rating ng sub mo kasi youre also feeding it an RMS rating of 600 watts. 8O

most 2ch amps i know di kaya mag mono below 4ohm when bridged. it does'nt mean it can't do it but its just not recommended coz something might go wrong.

did you link up the two alpine amps to produce 600w? parang 2 rf 500db's could produce 1000w via BD Sync Cable?

i didnt wire it to 2ohm mono naman eh...i have 2 same amps...dual 4 cya so i wired i4ohm bridged each amp...one coil per amp...kaya 4ohm lang..not 2ohm

yeah prolly reaching 600wrtms wid amps..pero bakit pag 1 amp lang tapos naka stereo..(not bridged) pumipitik pa din...hmmm(the sub should only be getting 300wrms...)

i didnt wire the sub to present a 2ohm load to the amp...i did not bridge it while using one amp only...nakastereo...so 4ohms each channel and load (1 coil per channel)

sir MAKI:
suggestion lang po.
u may use Lightning Audio BOLT series model B350.1
it is a mono amp 350watts RMS x1 at 20hms mono.
run ur L5 sub parallel to 2ohms then into the LA amp. Gud nato!!!
boom boom narin. have tried it 4tyms alrdy to 4diffrent customers.
price at 10k. may discount pa naman. call or visit my shop.
ty.

maki:
ndi ganung kasimple gnawa mo e. if u did use 1amp per voice coil, it is safe as long as u use vu meter to check each gain ng amp kng parehas ang out put. ndi kc pwede basta todo gain ng both amps. inaccurate parin kiahit both amps same brand and same model. ndi pareho ang out put ng isang amp to the other. kunyari, ung 1st amp mo naka set ang gain sa half, so vertiacal line ung makikita mong guhit sa knob, then ung second amp ganun din. pag chineck mo yan sa vu meter, may pagkakaiba parin ang power output. e ung dual voice coil ng sub mo, dual coil nt built separatelt but its made in only 1pole piece. pag iba ang output ng amps, imagine mo kilos ng coil na L5 mo... panu gagalaw ng matino? gets? its nt easy just tapping both amps to both coils. i wld strongly recomend u use a bigger amp atleast 400w rms or highest at 600w rms that is capable of bridging to 2ohm load mono. 2ohms kc dual 4ohms ung sub mo e.

choose between:
kx400.1 class D 2ohm mono amp
kx600.1 class D 2ohm mono amp
rf power 500bd class BD amp 2ohm mono amp
LA B350.1 class A 2ohm mono amp
ORION HCCA225 class A 2ohm bridged
ORION HCCA250 class A 2ohm bridged
and more......

i used a 60hz sine wave to simulate an AC signal na nagngagaling sa outlet ng bahay, then i used a digital VOM to meaure the output and set the gain....
