2007 Sedan. Base Audio.
I want to upgrade the system by:
-Adding amplifier
-Leaving existing Head Unit (HU)
-Adding Sub (still need room in trunk so not too crazy !)
-Possibly replace speakers in doors (including tweeters)

Not looking to bounce the streets with my sound but do want to improve the quality of audio......

Any thoughts or similar upgrades done out there? Any recommendations for any Audio shops in AZ (Phoenix metro area) that are reliable and produce quality work?

Thanks in advance !

 

If you want to come down to Tucson I know a good shop. I imagine thats not what you're looking for though.

Good luck.

 

in my car i put a fosgate 300.2 amp, peripheral hi low converter w/ built in remote, 4 ga wire, first i had a 8 inch kicker comp sub that goes in the stock sub place, then i put a 10in arc audio in the same place, then i took it out cause it doesnt sound good in free air, i was just tryin to save some space, then i put 2 12s fosgate p1s, now it sounds good matches the stock mids n highs fine not a overkill in bass. If i were you i would get the new MTX hi low converter is a lot better, n some jl subs n amp, would sound cleeen
