I have roughly $1000-1200 to work with for a relative's car audio system. The auto is a 2003 Chevy Silverado HD Crew Cab. The only place I saw room for a sub was in the limited space under the rear seats that flip forward. I'm looking for suggestions on subwoofer driver and amps. Here's what I had in mind: Dual Dayton Titanic 10" MKIII in separate 1.5CF or 2CF sealed box. $140ea Powered by dual 200W MTX class D amps. $89ea Koda 6.5" component car audio speakers from Adire Audio $350 Powered by 2ch MTX amp $120. 1 farad cap $70 $100-200 for wires, fuse, ICs, distr. block etc. I know I'm getting expensive speakers with inexpensive amps. I found that I just go over my budget if I choose amps by like Phoenix Gold. I'd prefer to get everything from one place like partsexpress. I'm pretty sure the amps will need to be the same brand for cosmetics. There's an existing DVD receiver with LCD and that stuff already installed, I'm just doing the sound. The speakers will go in the door, and I'll remove the factory rear speakers since 4x6" speakers will probably not go well with a high quality component set in the front. Whatever the speaker route is, it has to be component so the tweeters are separate. (For looks) I suppose the Q-form enclosure for the front speakers could be an option but it will add $150. The audio requirements are from an 18 year old boy.. I assume he wants Loud and clear, with rock music/hip hop etc + DVD movies and bloated bass... etc. Do you think higher quality amps with lesser quality speakers will be better? Oh, and I'll be making the install look real nice with 3/4" custom MDF enclosure, scribed in, carpeted, with in-set amps and hidden wires, you know... the works. I suppose I could model the Dayton drivers and see what I get with ported, or perhaps 1 sub is all I'll need. I don't know if I'm allowed to install sound dampening materials or bass shakers yet. Any advice?
