Recently having the thought of changing my speakers and adding amp and sub to my car. Got the following quotation from a JB HIFI Staff and he offered a discount for the package, not sure whether it is worth it. Alpine Amp - 4 Channel AMP MRP-F300 $335 (Original Price: $399) - Mono Amp MRP-M500 $499 (Original Price: $440) Alpine Subwoofer SBR-S122V $340 (Original Price: $398) Alpine Speakers (2 Sets Front and Back) 6" x 9" SPR-69c $210 (Original Price: $249) 6" x 9" SPR-69c $210 (Original Price: $249) Wiring Kit $120 (Original Price: $165) Installation $420 Total Price: $2134 Does anyone know of any places that i can get all the products for a reasonable price. Doesn't need to be Alpine, i have been to WOW, JB HIFI, Autobarn. I find that generally WOW price is cheaper for Brands that they carry like: Pioneer, Kicker, OnlineAudio and such. DJKOR has recommended me to get the same brand for my AMP and SUB, so does anyone know of a good place to buy and install everything? Please advise. Very much appreciated. I am staying in Sunnybank, Brisbane. Cheers.
