OK. Sounds good. If I were in your shoes, I would be looking to replace the door speakers. The Crystal 5x7s sold
here cost 69.00 per pair. Get a pair for the front and rear doors. ~$150.00 with shipping and power them with your HU.
For the sub in the rear deck, there are some good options out there...here are some of them.
Dayton Thruster 8" from
www.partsexpress.com for ~50.00 is a good budget upgrade and adds some much needed low end. It won't make your hair move, or wake the neighbors at night, but it's quite nice.
The JL Audio 8IB4 is a little better suited to a free air enclosure but has similar specs to the dayton and will cost you a bit more money. It's a good option especially if you can find a deal on it.
If you want to spend quite a bit more money (160.00) you can step up to a Scanspeak 21W/5555A from
www.madisound.com. With a 10mm (14mm max) xmax, it should be able to move some serious air for an 8". It would only take 50 watts to really get this speaker to work well. If you could give it 100 watts, you'd be happy.
An Audiobahn AW831 is another decent option. You should be able to find it in the 50.00 price range.
For an amp, Look into a JBL BP150.1
