Stereo upgrade choices

First off I live on the Big Island of Hawaii, so there are not a lot of choices in car audio shops..
I went to a shop yesterday and the guy recommended an all alpine set up. I like the slim sub woofer an

$250 Alpine SBR-S8-4 Slim Box Car Ported Enclosure with One 8" Type-R Under Seat Subwoofer 1000 Watts Power

Alpine SBR-S8-4, it fits behind the passenger seats. He recommended the Alpine SPS-619, 6 x9 3 way speakers, Alpine tweeters and the Alpine MRV F-300 amp 50 RMS 4 channel. I'm leaving the rear speakers alone, so he is bridging two channels for the sub.

The shop does not have any demo spot for listening, so I have to take his word, that this will sound great.

I have been looking online and like what I have read about JL Audio. The 6 x 9 C2-960TX , is rated very well, with great reviews. As is the JX 400 70 rms amp and the micro 8" sub box.

Looking for some advice from anyone out there, with any experience with these products and I'm open to suggestions. I don't want to try the install myself and I'm keeping the head unit.

 

Cant go wrong with Alpine. I have an Alpine head and Alpine pdx series amp. No problems what so ever. JL sub and Focal speakers. Very nice set up. I wanted alpine speakers , but the Focal had crisper highs. Almost to high at times. I thought the alpines were a bit softer sounding , which isnt bad. Sometimes my tweeters are to much, when the cymbals are hit - it hurts my ears and they wash out. I think you will be happy with an all alpine set up. I also opted for a single 10 " sub , I wasnt trying to impress people out side of my truck. On e in the right box will provide a nice sound inside. 6 x 9 's will be cool. Thats what I was going to grab , but I went with Components up front and 6 .5 " 2 way in the rear. Happy happy....
On a side note - I first got the JL amp and it gave me problems. it ran hot and one of the channels would cut in and out. Swapped it for an alpine. JL fixed the amp free of charge, but I didnt trust it after that.

 

I opted for the OEM Audio+ Reference 450Q. Installed it in a few hours yesterday. All plug and play. Incredible crisp sound.

 

I was watching the oem audio installation video yesterday. It looks pretty sweet. I have the jbl in my truck and it sounds good for what I use it for but the oem audio would be my install if I didn't have the jbl. It looks stock with the aftermarket sound. Kind of pricey though.

 

How did this turn out?
