Question about Alpine MRP-M450 Car Audio Amplifier
I have a 99 GMC Denali I had a local store hook up all the stuff to adapt from bose system to a after market CD player a Alpine model# cda-9827 and I put a sony 1200 watt amp in to.My problem is I can't get the amp to work or push the subs.I've did everything.I also noticed when I un hook the rca the subs where still leting the sound from the radio come through.It's driving me nuts i really need help please....
Recently had this amplifier and 2 12'' Alpine type E subwoofers installed on my 2000 GMC Yukon Denali at best buy. They don't sound nearly as loud as they should. I know because I've had these subs and the same amp installed in 2 other cars.
The person that installed them at best buy recommended that I get a better stereo deck, but I'm still not entirely convinced that he wasn't just trying to sell me something. Especially since they worked fine on the last 2 cars that they were in, which were both Jeep Grand Cherokee's with only the stock decks. How can I get the thunder back?
Thanks in advance.
My homie had the same problem with his escalade they adapted an rca line adapter from the factory wiring to geta signal to his amplifier and it just wasnt hitting like it should so we installed a new deck and plugged the rca cords right into it and boomboom pow it was hittin like a champ-we figured that the stock premium system that was incoprporated into the truck had some sort of an onboard amp that was filtering the bass from the door speakers and which was limiting the bass output to the rca adapter and thus on down the line to the amplifier- so maybe ya might want to look into getting an aftermarket deck and see if that helps your cause-good luck
