Partsrep, did you get a chance to listen to the Scion head unit with the factory stock speakers? I've shopped around on ebay and found that I'd be spending about $200 for the Infinity speakers. Somone has agreed to sell me their single disc Scion HU for $125. I'm also bidding on a Kenwood wOOx subwoofer that's got a "Buy it Now" price of $109.
I figure the whole set up will run me about $500+ with installation. If I skip the speakers for the time being, will the sound still improve over the stock Toyota head unit. I'm getting engaged this summer and really need to curb my spending.
Also, do you have a subwoofer installed. I peeked under my driver's side seat and although the Kenwood wOOx is a pretty compact subwoofer, I'm not sure it will fit under the seat anyway. If it doesn't, I won't add the subwoofer because I don't want to lose any cargo space, nor do I like the look of a box sitting permanently in my cargo area. If that's the case, how's your base without a sub? I don't need booming base that drowns everything else in a song. I like tight base that sounds clear and complements good mids and highs.
Finally, if I do nothing else other than a straight swap of the head units, does the HU cut the appropriate frequencies to the speakers so they don't blow, or do the stock speakers have frequency blockers installed at the wiring points? In other words, do I need to worry about buying bass blockers or some sort of crossover device?
Thanks and sorry for the long questionnaire.
