blaupunkt used to be a decent brand long time ago but now went downhill. as for nakamichi i dont think its made in jpn anymore. brand wise should be better than blaupunkt. thats why i always opted for oldschool stuff usually made in us or jpn. much cheaper than latest stuff made in us/france. but used item comes with reliability issue. nasib la. also i like to diy my own system.

for non diy-er like urself, & summore happy with ur buy, good la. summore can save boot space.

my 1st time into car audio. go kedai accs that ppl recommend, spent 1.5k for HU, front coaxial, 4ch amp & 12" sub. its loud but the quality so-so nia. even the power cable from battery not even pure copper. its the sampah copper clad aluminium (CCA). just recently found out after i dismantle everything.

Yeah sony and blaupunkt went downhill already. Since i am not buying high end stuff, i choose nakamichi je. My iniital plan is cheapo blaupunkt sub, then uprade to blaupunkt gtr110, but the installer said the blaupunkt gtr110 some have issue of sapping the car battery so he no longet take in the stock.

Mine also is sampah aluminium cable huhu. For that price...i dont think can expect full copper la.

Rm200 sounds about right since installation + tuning. installation kuli biasa bole buat but tuning must at least audiophile kinda guy. usually the bos / owner or seasoned staff.  it really took sometime coz need to match the clipping point between the sub & speakers. summore need to tune the sub to sound like its coming from the door speaker/everywhere. if u can locate the subs location when listening to music, the installer fail big time. for me this is the hardest task to achieve. be it in car audio or home stereo system (bookshelf speaker + sub setup).

Yeah tuned by the boss. The anak buah do the installation. And yes the sub sounds like its coming from everywhere hehe.

honestly i cant afford audio grade oxygen free copper (OFC) cable. 1 meter 4awg size already cost rm40-50 brand biasa2 oni. after long research on net, i decided to buy pure copper welding cable 00awg size rm23 per meter. big ass cable. almost like getah paip air. laugh.gif

its not super flexible like the audio cable but the jacket/skin got double layer. can stand high heat. too bad malaysian welding cable not yet move to ofc standard like usa. anyhow, for the size & price, damn worth it.

TBH i dont know how they tune their subs,
i used to have a 1.2kW (yes, 1200W Boston Acoustic amp) with a 12inch matching sub + passive radiator, i can crank it up till the extent that's unbearable and it's only barely audible outside the car

IIRC, you need to double the size of CCA for the same performance on pure copper wire. u also get twice the heat from CCA. every strand of CCA wire made from aluminium. only the outer layer of each invidual strand covered with copper. so CCA is a big no-no for me.

but if ur ears are happy, any wire aso can la.. laugh.gif
