Alright, all this time worrying about subs and i have been neglecting my mids and highs. The cars pretty loud now, 4 speakers all running of the HU. Two xplods in the back and these are the ones that i plan on replacing. I just bought some pioneer 4x6's for upfront and they sound amazing for the price. I don't plan on getting rid of those until they blow.
Now with the rear speakers on the deck. I currently have an unused MTX RT 202 amp. I was planning on hooking it up to the back speakers only. Or could i hook it up to all four?
Also, i got to thinking. My subs are in the trunk and the back speakers are on the deck and go into the trunk. I'm pretty sure the subs end up making my cones move and might cause distortion. Anyone else have this problem? Fixes? You guys are the experts.
