Good day!

Pa suggest sana ako ng magandang audio upgrade for my trailblazer. Currently running stock HU and straight infinity primus. Seps up front, coax at the rear with amplifier and underseat subs. Hindi na ako satisfied sa sound quality kasi nilipat lang from previous car kaya medyo matanda na ang buong system.

I prefer SQ setup. Open budget and any good brand will do.

Thanks
