[QUOTE="CivicHatch, post: 8249639, member: 660541"] Hello Everyone. So a few months ago i bought an Alpine SBG-1244BP Type G and an MRV-M500 Amp. Everything was working very good had and had no problem, it was wired by a professional. The sub was very strong and you could feel it do it's job the whole car was shaking [IMG]//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif[/IMG] But one day i was trying to start my car and the battery was absolutely dead, so i bought a new battery and after the new battery the sub is not what it used to be.. In the start the sub was EXTREMELY weak you couldn't feel it at all but in a few days it started working ''okay'' but it is still not as strong.. It doesn't have that spark to it anymore. I took it to some car audio shop and he turned some things in the amplifier and he said that he thinks that the sub is giving it all, but i know it isn't. Also off topic but shouldn't the SBG-1244BP be shining blue inside? No light in mine. Not even before battery change. Is there any switch or something somewhere? Could anyone please help me or clarify the sudden bass decrease? The car is an EP3 Type R Civic. [/QUOTE]
